HM-MOD-RPI-PCB & Raspberry Pi 4

Hello, I’m struggeling with new RPi4 (4GB) and Homematic HM-MOD-RPI-PCB module. I come from the same OH 2.4 setup on RPi3. I followed the installation process as on RPi3 (explained here). Did anyone get the module working on new RPi4 4 GB model?
Thanks for any hint!

If Homegear is using WiringPi then try this one:
http://wiringpi.com/wiringpi-updated-to-2-52-for-the-raspberry-pi-4b/

It seems that WiringPi is outdated on Buster.

Thanks, Christian. I used the recommended serial connection via /dev/ttyAMA0. I guess there ist no WiriPi involved since I would find more issues about that problem.
I’m not sure if the openhabian-config setup of homegear works on the RPi4 at all, because I get a lot of error messages without doing anything apart from the documentation.

Is anyone successfully running OH 2.4, Homegear (and HM-MOD-RPI-PCB module) on RPi4 4GB?

Hello,

any update on this topic? Does it work right now?

Best regards

Hi, i also agree with this problem. My plan was to move from RPI3 to RPI4 and start there with an fresh OH installation.

After installing Homegear over sudo openhabian-config homegear runs without issues but the HM-MOD-RPI-PCB will not connect. And its not possible to connect any device.

And before the question is asked: Yes, adjustments to /boot/config.txt and /boot/cmdline.txt were made. Used instructions: Instructions for RPI

In my old installation (RPI3) this all still worked

NOW RPI4

Additionally I have also done a firmware update without FHEM: Update Steps → successful

Is the current version perhaps not mature for buster or does one of you have a tip ?

Please double check the configuration file for errors or misconfiguration. I forgot to uncommend one headline, that solved my issue.

In general in can confirm: The module works fine with RPi4 and same setup as before.

Are you using the new 1.5 openhabian with Buster ?
Somehow the installation of homegear only creates problems… and i just cant get it to work.

I made all updates incl. Buster. But I’m not sure, if all that was entirely necessary.

Thank you. But there is still no solution for me. The new openhabian (Buster) changed authorizations.

I refer to this thread Faulty homegear installation over openhabian
and one thread in the homegear forum (in german) Openhabian homegear error

I will pursue these and hope for a quick solution.
