There are many resources available, some of which are listed below, but several points deserve mentioning in this document: compatible properties are the link between the hardware description and the driver software. via PRs or maintain these changes in a fork for the time being? Do you think it might be possible to move all this into the main RaspberryMatic repository? If you changed any of those, raspi-config will ask if you wish to reboot now when you select the <Finish> button. What would be the exact process of that additional container? Alongside the dtoverlay and dtparam commands is a utility for applying an overlay to a DTB - dtmerge. What does this kernel_modules: true option do in HA? This is the file to configure wireless network settings (if the hardware is capable of it). Boolean parameters are declared like this: where label and property are replaced by suitable values. If desired you can add something after the final "/" to add a prefix to each file, although this is not likely to be needed. This sounds like some additional lighttpd config tuning within RaspberryMatic could help to actually solve these reverse proxy problems. Already on GitHub? One is private, and one is public. The resulting new wireless network is entirely managed by the Raspberry Pi. You can mount your storage device at a specific folder location. CCU/HomeMatic service changes: updated OCCU version to 3.65.6-3 which comes with the following changes: updated ReGaHss logic engine to… Read more, This is release 3.63.9.20220625 of RaspberryMatic which is a maintenance release with the following bugfixes and feature changes: Hier klicken für deutschsprachige Version des ChangeLogs/Diskussionsbeitrag Changes: For all changes, see the full commit log. I already thought about permanently forking the HAos project just for HomeMatic purposes. War es nicht mal so, dass die Firmware beim Backup mit übertragen wird ? If secure-boot is enabled then this bit-field will be non-zero. Don’t create a node within a fragment that will overwrite an existing node in the base DTB - the kernel will rename the new node to make it unique. Failure to adhere to this may cause some or all of your fragments to be missed. The ACPI kernel driver for Thinkpad devices is enabled. The config parameter “valve switchover value” can now only be activated/changed for a. Meanwhile, I was able to make the switch to xmlrpc and Raspberrymatic after a couple of issues. Put this file onto the boot folder of the SD card. I assume this is how you issue CL commands. Now select the Option named, Audio (Currently option S2, but yours may be different) and press Enter: Select your required mode, press Enter and press the right arrow key to exit the options list, then select Finish to exit the configuration tool. But the new HA 6 RC1 64Bit itself cant find the devices and cant connect the raspberrymatic proxy. IP address for the container instance (e.g. If you prefer to install all prerequisites, dependencies manually on your docker host system as well as prefer to create the docker container manually or if you are using docker solutions like docker compose, please make sure to following the following procedure in a step-by-step manner. Make sure, however, to update the script over time (in case you downloaded it) because we might introduce changes to it as we move forward. I have some updates/questions. Enable/disable the experimental GL desktop graphics drivers. IMHO this issue should be better reported to the Homegear developers/project because they should actually make sure that the used rf module will carry the firmware version they require, thus perform a firmware downgrade if required. DT overlays allow optional external hardware to be described and configured, and they also support parameters for more control. with an NTP server. If the primary UART is ttyAMA0 then enable_uart defaults to 1 (enabled), otherwise it defaults to 0 (disabled). It is possible that some USB dongles may need slight changes to their settings. Ralink rt27xx/rt28xx/rt30xx, as well as Realtek 87xx/88xx devices, are now If you are using a Raspberry Pi 4 with more than one display attached, then tvservice needs to be told which device to ask for information. Now I need to pair all devices again, but that's not tragic. This addon can be used to easily up- and downgrade the RaspberryMatic system. The firmware loader (start.elf and its variants) is responsible for loading the DTB (Device Tree Blob - a machine readable DT file). The secondary UART is not normally present on the GPIO connector. Compatible kernels manage a stack of overlays that are applied on top of the base DTB. Wie auch immer, jetzt weiß ich ja bescheid. You should click on "RESET TO DEFAULTS" and restart the add-on. allow to think about moving towards using HAos as a complete new base system for RaspberryMatic (while calling it "OpenMatic") since it has a better UI, integration, etc. really. The mini-UART has smaller FIFOs. Set the behaviour of a GPIO connected fan. To me, this looks like all *.cgi scripts are causing this exception. To add them to the sudo group to give them sudo permissions as well as all of the other necessary permissions: You can check your permissions are in place (i.e. Command variants that change kernel state (adding and removing things) require root privilege, so you may need to prefix the command with sudo. Each pins_* section can contain pin_config and pin_defines sections. For example: There are some differences between PL011 UARTs and mini-UART. Add consoleblank=n to have the console blank after n seconds of inactivity. Find the disk partition from the list and note the UUID. route-string - 32-bit integer The private key should never be released, but the public key can be freely shared. On the Raspberry Pi 4 and Raspberry Pi 400 to specify the HDMI port, add an index identifier to the hdmi_group or hdmi_mode entry in config.txt, e.g. If no port identifier is specified, the settings are applied to port 0. some children for node1: child-node1 and child-node2. What you'll need Raspberry Pi with Raspbian Network and internet connection VNC Server and VNC Viewer Step 1: Enable VNC First, make sure both your Raspberry Pi and the other computer you're going to use are connected to the same network. ↳   HomeMatic Zentrale (CCU / CCU2 / CCU3 / Charly), ↳   HomeMatic Aktoren und Sensoren (klassisch), ↳   HomeMatic IP wired Aktoren und Sensoren, ↳   Softwareentwicklung für die HomeMatic CCU, ↳   Softwareentwicklung von externen Applikationen, ↳   Hardwareentwicklung und Selbstbau von Aktoren und Sensoren, ↳   HomeMatic Apps und Desktop-Anwendungen, ↳   Externe Steuerungen und Visualisierungen, ↳   Sonstige Steuerungen und Visualisierungen, FHZ-, FS20-, HMS100-, FHT-, KeyMatic- & sonstige Hardware, ↳   ELV FS20 Sender, Empfänger und Aktoren, ↳   ELV KeyMatic Funk-Codeschloss & Türschlossantrieb, ↳   Sonstige Hardware (Vellemann USB-Board, IRTrans, ALLNET), ↳   homeputer Studio / Standard: allgemeine Fragen, ↳   homeputer Studio / Standard: Programmierbeispiele, ↳   homeputer Studio / Standard: Bugs & Updatewünsche, RaspberryMatic 3.41.11.20181126 - downgrade nicht möglich (edit:doch), Re: RaspberryMatic 3.41.11.20181126 - downgrade nicht möglich, viewtopic.php?f=65&t=36361&p=472431&hilit=crRFD#p472431, Re: RaspberryMatic 3.41.11.20181126 - downgrade nicht möglich (edit:doch). If you are using a hidden network, an extra option in the wpa_supplicant file, scan_ssid, may help connection. If nothing happens, download Xcode and try again. You can have greater control over the settings by editing config.txt. pins_bplus1 Raspberry Pi 1 Model B+ rev 1.1, including the full 40pin connector. If no errors were detected, the file will be saved and you will be returned to the shell prompt. Note that you should only do the generation process once: if repeated, it will overwrite any previous generated keys. /proc/device-tree exists, and contains subdirectories and files that exactly mirror the nodes and properties of the DT. If not, check your password and ESSID are correct. A derived configuration can then include that .dtsi and set the status for the devices which are needed to okay. von Mac_ » 08.12.2018, 15:04, Beitrag My setup: • Raspberry Pi 4 Model B; 4 GB • Home Assistant OS 7.2 • Addons installed: File editor (5.3.3), RaspberryMatic CCU (3.61.7.20220115) • Telekom branded Wireless Stick What I have tried: use Google Coral Mini PCIe Accelerator or M.2 Accelerator on all boards If for some reason you want to suppress the loading of the HAT overlay, put dtoverlay= before any other dtoverlay or dtparam directive. I only run a CCU instance as an addon in Home Assistant. The rpi-bootloader-key-convert utility can be used to convert the data into PEM format for use with OpenSSL. https://github.com/home-assistant/operating-system, https://github.com/jens-maus/RaspberryMatic/wiki/Installation-HomeAssistant, https://github.com/jens-maus/RaspberryMatic/tree/master/home-assistant-addon, https://github.com/jens-maus/operating-system/releases/tag/rm-testversion, Support for RPI-RF-MOD/HM-MOD-RPI-PCB for HomeMatic/homematicIP communication, https://github.com/home-assistant/operating-system/releases, https://github.com/jens-maus/ha-addon-raspmatic, https://github.com/jens-maus/RaspberryMatic/wiki/Experten-Features#hb-rf-eth-anbindung, https://github.com/jens-maus/operating-system/tree/rpi-rf-mod-support, CONFIG_RT_GROUP_SCHED=y leaves docker with no available cpu.rt_runtime_us resources to share, preserve /usr/local in Home Assistant - binding to /data, https://github.com/home-assistant/addons/blob/master/homematic/rootfs/etc/nginx/nginx.conf, added a dedicated nodejs based http proxy that will proxy http requests, https://github.com/multiarch/qemu-user-static, https://github.com/angelnu/pivccu-modules-container, https://developers.home-assistant.io/docs/add-ons/configuration, ZHA can't connect to ConBee 2 stick when RaspberryMatic addon is running in HA OS 6.0.RC1, https://homematic-forum.de/forum/download/file.php?id=87959, "not enough real-time shares" on HomeAssistant OS, Recreate Supervisor container on OS upgrade/downgrade, https://www.home-assistant.io/integrations/homematic/#detecting-lost-connections, https://github.com/jens-maus/RaspberryMatic/wiki/Installation-HomeAssistant#home-assistant-integration-setup, HA Addon Anzeigefehler und Backup/Software lässt sich nicht hochladen/installieren, Jan 2021: First working technology preview. The Screen Configuration tool (arandr) is a graphical tool for selecting display modes and setting up multiple displays. Maybe there is a way to prevent this. The author can usually be found on Raspberry Pi forums, particularly the Device Tree forum. One such aspect is dhcpcd, the DHCP client on the Raspberry Pi, automatically requests an IP address for every active interface. ... mit Charly hatte ich tgl bestimmt 3-4 Fehlermeldungen, manchmal mehr ... IP Geräte FW Updates... lange her. For nodes added at run-time there is the further limitation that the bus must register for notifications of the addition and removal of children. The system can be easily connected to a WiFi network. This is the bootloader, which is loaded by the SoC on boot, does some very basic setup, and then loads one of the start*.elf files. Default: "" (will be automatically determined or interactively requested), time allowed to stop the container before Docker kills it. von Holger76 » 08.12.2018, 23:05, Beitrag Finally, we need to disable password logins, so that all authentication is done by the key pairs. A bridge network device running on the Raspberry Pi will connect the Ethernet and wireless networks using its built-in interfaces. The contents don’t matter, it can be empty. When this file is present, SSH will be enabled on boot. If possible, I would like to have all this in the main RaspberryMatic GitHub repository so that it can directly act as a home assistant addon repository. device_tree_end What do you mean by "does not work with HA nginx!"? So sorry if this affected your downgrade to homegear after your endeavor with RaspberryMatic. If you prefer, you can choose to skip the routing by skipping the section "Enable routing and IP masquerading" below, and run the wireless network in complete isolation. The localisation submenu gives you these options to choose from: keyboard layout, time zone, locale, and wireless LAN country code. I am curious how it goes when you propose to PR to the HA code - they are very careful on what code they add there... You mean for the required kernel modules changes in the HAos to support this RaspberryMatic Add-on? In order to allow traffic between clients on this foreign wireless network and the internet without changing the configuration of the main router, the Raspberry Pi can substitute the IP address of wireless clients with its own IP address on the LAN using a "masquerade" firewall rule. Installing a Homematic IP radiator valve using RaspberryMatic on Home Assistant Phillip Home Assistant, Home Automation 05/08/2021 5 Minutes In this guide I'll try to explain how to use the HM-MOD-RPI-PCB on the same Raspberry Pi as Home Assistant without using the Home Assistant provided Homematic CCU container. Heimautomation mit ELV HomeMatic und FHZ Funk-Hauszentralen, Beitrag Gaps in security leave your Raspberry Pi open to hackers who can then use it without your permission. By hiding the details of this mechanism behind commands the aim is to insulate users from changes in the event that a different kernel interface becomes standardised. For more information on each Linux command, refer to the specific manual page using the man command. I'm running the Conbee II with deCONZ addon instead of ZHA without any problems next to the RaspberryMatic Addon (HassOS 6.0.RC1 / supervisor-2021.05.dev1204 / core-2021.5.3). If this is the case and the script notifies to do so please re-run it with sudo rights accordingly: In addition, this script might request some additional information from you, like specifying a reserved ip address () which will be assigned to the container as well as a so-called auxiliary ip address () which will be assigned to the host system itself so that it can communicate with the started docker container. Second bug is, that the Hinzufügen-button is not working (green). Are you able to repro the problem? After you have finished modifying your audio settings, you need to restart your Raspberry Pi in order for your changes to take effect. Davor hatte ich den online update 3x probiert, nach 30min dann abgebrochen. Selecting this option shows the following warning: Be aware that overclocking may reduce the lifetime of your Raspberry Pi. Set to 1 if the tryboot flag was set at boot. Wireless connections can be made via the network icon at the right-hand end of the menu bar. In fact, the mechanism is so similar that when resolving symbols, the Raspberry Pi loader will search the "aliases" node in the absence of a __symbols__ node. The country code used used by PiWiz - Pi400 only. Please note that with the current Raspberry Pi OS distribution, there are some aspects that require the pi user to be present. If you are running the Raspberry Pi desktop then rotation is achieved by using the Screen Configuration Utility from the desktop Preferences menu. If you changed any of those, raspi-config will ask if you wish to reboot now when you select the button. As I figured out, CUxD is trying to connect to the conbee. plymouth.ignore-serial-consoles: normally if the Plymouth module is enabled it will prevent boot messages from appearing on any serial console which may be present. This flag tells Plymouth to ignore all serial consoles, making boot messages visible again, as they would be if Plymouth was not running. If your storage device uses an exFAT file system, install the exFAT driver: If your storage device uses an NTFS file system, you will have read-only access to it. Once again, this is something you can change using the raspi-config tool. Work fast with our official CLI. In usage it is largely equivalent to dtoverlay with an overlay name of -, but there are a few differences: dtparam will list the help information for all known parameters of the base DTB. In some rare cases you may need to increase the HDMI drive strength, for example when there is speckling on the display or when you are using very long cables. The following HOWTO is highly experimental. You will probably want to use 'e' for '(e)dit sudoers file again', so you can edit the file and fix the problem. Aliases are similar to labels, except that they do appear in the FDT output as a form of index. Sign in true for the OVA image for virtualized environments (when using hardware For me, it looks like the "api/hassio_ingress"-part of the request URL is missing. The names of child nodes should be qualified with their addresses in hexadecimal, using @ as a separator: When assigning to the reg property, the address portion of the parent node name will be replaced with the assigned value. Parts of the Device Tree are only used at boot time - changing them using an overlay will not have any effect. You should then see a blue screen with options in a grey box: Use the up and down arrow keys to move the highlighted selection between the options available. Connect your Raspberry Pi to the Ethernet network and boot the Raspberry Pi OS. So can you give this nodejs-based proxy a test and see if you can spot some obvious problem compared to the nginx proxying the homematic occu add-on authors are using? The Raspberry Pi can be used as a bridged wireless access point within an existing Ethernet network. Enable or disable predictable network interface names. Note the line country_code=GB: it configures the computer to use the correct wireless frequencies in the United Kingdom. If non-zero, turn on some extra logging for the firmware’s device tree processing. You can download it from GitHub. See this page for more information. display_hdmi_rotate is used to rotate the HDMI display, display_lcd_rotate is used to rotate any attached LCD panel (using the DSI or DPI interface). The two most useful overlays are disable-bt and miniuart-bt. Enable/disable remote command line access to your Raspberry Pi using SSH. If the status is ok, okay or absent, then the device is enabled. updated RaspberryPi kernel+firmware to latest 1.20210527-1 tagged version. A tag already exists with the provided branch name. After experimenting a bit, I found a few bugs. reinstalling. Just wanting to let you know this problem. It worked fine, in it's isolated environment, without urge to upgrade. It's the Pi3 which requires some work due to the Bluetooth &WLAN interfaces. Note that on Raspberry Pi devices that support the 5GHz band (Pi3B+, Pi4, CM4, Pi400), wireless networking is disabled for regulatory reasons, until the country code has been set. These are binary blobs (firmware) that are loaded on to the VideoCore GPU in the SoC, which then take over the boot process. There are many firewall solutions available for Linux. Changes usually take effect immediately, but may require a reboot. You add a line to the config.txt file to apply a Device Tree overlay. It should include the name of the base CPU, its memory configuration, and any peripherals (internal and external). Under the hood, the OS was updated to the latest upstream Linux 5.10 kernel But if not (or as an alternative strategy?!?) When you have the required setup, click the Tick button to apply the settings. The IP address or hostname and port of your proxy server, A username and password for your proxy (if required). I also added the dev documentation for building both the Add On and RaspberryMatic inside a container. This option will expand your installation to fill the whole SD card, giving you more space to use for files. Reflection can be one of 'normal' 'x', 'y' or 'xy'. Now I am in a rush to set up Raspberrymatic (with XMLRPC) to get my Homematic gear working again. USB boot using the BCM2711 USB host controller. x86-64”. Perhaps this is a lighttpd conf issue within the RaspberryMatic docker. using docker pull) so that you retrieve the very latest version of the RaspberryMatic docker with the next execution. And if you could point me at resources and provide a quick howto and show how I can get your current Addon going, that would be highly appreciated! String parameters can cause their target properties to grow, shrink, or be created. The overclocking you can achieve will vary; overclocking too high may result in instability. Already with OS 5 the "Intel NUC" image was usable for most UEFI capable x86-64 systems. answer 'No', At the prompt Would you like the serial port hardware to be enabled? Save the file to complete the IP configuration of the machine. This means that it can be read on Windows, macOS, and Linux devices. If it works then yes, it would be good to keep it in a single place. One you may have noticed already - status - which will convert a boolean to either okay for true and disabled for false. The WIP repository already looks quite promising. Europe, then selecting a city, e.g. You must also enable 4Kp60 output by setting the hdmi_enable_4kp60=1 flag in config.txt. Select your local time zone, starting with the region, e.g. Back in section 1.3 it says that "the original labels do not appear in the compiled output", but this isn’t true when using the -@ switch. There are some differences because of the moved I2C pins. 1 - Disable remote GPIO, Setting is one of: E.g. CCU/HomeMatic service changes: updated OCCU version to 3.69.6-3 integrating full compatibility to the CCU3 3.69.6 firmware which comes with… Read more, This is release 3.67.10.20230225 of RaspberryMatic which is a maintenance release with the following bugfixes and feature changes: Hier klicken für deutschsprachige Version des ChangeLogs/Diskussionsbeitrag Changes: For all changes, see the full commit log. bootcode.bin is not used on the Raspberry Pi 4, because it has been replaced by boot code in the onboard EEPROM. used on some newer Intel NUC devices. The dtoverlay and dtmerge utilities have been extended to support the map file: dtmerge extracts the platform name from the compatible string in the base DTB. Power-on — pins default to inputs with default pulls; the default pulls for each pin are described in the datasheet, Setting by the GPIO command in config.txt. It is kept up-to-date with additions and changes. If nothing happens, download GitHub Desktop and try again. On almost all models, i2c1 belongs to the ARM and i2c0 to VC, where it is used to control the camera and read the HAT EEPROM. Note that DTS requires semicolons after closing braces: think of C structs rather than functions. You can either upload these files using the WebUI-based update mechanism or unarchive them to e.g. The locations of nodes and properties within the tree can be described using a path, with slashes as separators and a single slash (/) to indicate the root. CCU/HomeMatic service changes: updated OCCU version to 3.67.10-3 integrating full compatibility to the CCU3 3.67.10 firmware which comes with… Read more, This is release 3.65.11.20221218 of RaspberryMatic which is a maintenance release with the following bugfixes and feature changes: Hier klicken für deutschsprachige Version des ChangeLogs/Diskussionsbeitrag Changes: For all changes, see the full commit log. aspect_ratio should be one of the following: For the Raspberry Pi 4 and Raspberry Pi 400 to specify the HDMI port, you can add an index identifier to the config.txt. Store the password in a text file and input it to wpa_passphrase by calling wpa_passphrase "testing" < file_where_password_is_stored. The addition of embedded literal assignments allows a parameter to write arbitrary values, regardless of the parameter value supplied by the user. To install all necessary third-party dependencies on the docker host system for the RaspberryMatic container to work correctly the following step have to be performed one after another: Install pivccu-modules-dkms kernel modules (required for RPI-RF-MOD, HM-MOD-RPI-PCB or HmIP-RFUSB use) by executing: If you are using a RaspberryPi and want to use a RPI-RF-MOD or HM-MOD-RPI-PCB connected to GPIO (NOT necessary if you want to use a HB-RF-USB, HB-RF-USB-2, HB-RF-ETH or HmIP-RFUSB): Install the necessary device tree patches: NOTE: If there is no /boot/config.txt, you may put these changes under /boot/firmware/usercfg.txt. The utilization of quotes around the ssid - psk can help avoid any oddities if your network ssid or password has special chars (! to attach a keyboard to login. It will then search for parameters foo and level, and assign the indicated values to them. as GitHub blocks most GitHub Wikis from search engines. The current supported platforms are bcm2835, which includes all Raspberry Pis built around the BCM2835, BCM2836 and BCM2837 SoCs, and bcm2711 for Raspberry Pi 4B. The default for this is the default for the chip, so it is a useful source of information about default pull ups/downs on the chip. PS: In step 3 you have to change the entity_id with yours (like homematic.raspberrymatic) two times ;). First bug is encoding errors with umlauts and degree values (red). This can be done by using raspi-config: At the prompt Would you like a login shell to be accessible over serial? This won’t include overlays and parameters, but it also won’t include any other modifications by the firmware. Properties are simple key-value pairs where the value can either be empty or contain an arbitrary byte stream. Each item in this section must be a named pin section, such as pin@p32, meaning GPIO32. In order to work as a bridged access point, the Raspberry Pi needs to have the hostapd access point software package installed: Software installation is complete. Now, for persistence, I did not find a way to map /data which is the folder passed by HA for add on persistency to /usr/local so I will have to add an env variable to tell Raspberrymatic that is running in HA and use that info to bind or symlink /data to /usr/local. You will be prompted to create a password for the new user. The Raspberry Pi Zero, 1, 2, and 3 each contain two UARTs as follows: The Raspberry Pi 4B and 400 have an additional four PL011s, which are disabled by default: The first generation Compute Module, together with Compute Module 3 and Compute Module 3+ each have two UARTs, while Compute Module 4 has six UARTs as described above. If you are still unable to unmount the storage device, you can use the lsof tool to check which program has files open on the device. - Turbo - Overclock to 125% of the maximum, 0 - Enable overlay filesystem What kind of hardware/operating system are you using for OH? It will also route between the wireless and Ethernet networks, providing internet access to wireless clients. As said, I do have very less experience with HA and especially regarding development for HA. Instead, every label results in a property in the __symbols__ node, mapping a label to a path, exactly like the aliases node. The main router will see all outgoing traffic from wireless clients as coming from the Raspberry Pi, allowing communication with the internet. This is indeed a good hint. We would not need to expose the modules to the RaspberryMatic container -> once they are added to the host by running the new "install-modules" container then they are automatically loaded once of the devices is detected. How to construct a Device Tree, and how best to use it to capture the configuration of some hardware, is a large and complex subject. But of course also thanks to all testers in here! You could also install an older RM Version, which brings an older Firmware and it will downgrade automaticly. This includes the additional codec pins on P5. Sign in Download the file rmupdate.tar.gz and install the addon in the HomeMatic WebUI of your Raspberrymatic. passthrough mode as well. WebUI… Read more, This is release 3.65.11.20221005 of RaspberryMatic which is a maintenance release with the following bugfixes and minor feature changes: Hier klicken für deutschsprachige Version des ChangeLogs/Diskussionsbeitrag Changes: For all changes, see the full commit log. We could also use it for the deployer.sh so it avoids downloading each time from apt. SSH allows you to remotely access the command line of the Raspberry Pi from another computer. Generally speaking, raspi-config aims to provide the functionality to make the most common configuration changes. I indeed was thinking in a "plan B" -> they support passing the kernel modules (and I think headers) to the add-on. Overlays loaded after this one can then refer to &public. On all models of Compute Module, the UARTs are disabled by default and can be explicitly enabled using a device tree overlay. They are defined like this: Note that a property is assigned the value false by not defining it. On easy mode connections between a HmIP dimm/switching actor and a HmIP motion sensor the type of retention time can now be selected. I have to see if there is an option to also make the kernel sources available to the add-on since it is so limited what folders can be provided to the add-on. Addon for RaspberryMatic to (auto) update system Support Quality Security License Reuse Support I expected that Raspberrymatic would not alter my hardware or at least ask me before doing that. The latest Bluetooth firmware for When switching back to the SD card with Homematic I slowly realized that the setup stopped working due to the HM-MOD-RPI-PCB firmware having been replaced and now being incompatible with Homegear. The default username and password is used for every single Raspberry Pi running Raspberry Pi OS. But I got an information to downgrade my device.
