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It seems that WiringPi is outdated on Buster.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?
