And so here is my serial gateway with 3d printed case:

Ah I found it using:

sudo systemctl disable mysgw.service

Now when I reboot the pi the gateway is working and my sensor node is reporting correctly.

Thanks for everyones help, it's been 2 years since I last played with openhab and mysensors, and what I learned back then I had mostly forgotten. Also with the openhab and mysensors updates that have happened in that time it's been a struggle to get back on track :grin:

@mfalkvidd Ahh ok, so it seems that my openhab setup is the problem here. I will continue to try to understand the problem, since the whole purpose of the raspberry pi upgrade was to upgrade openhab to version 2.2.

I'll hop over to their forums and try and understand what has changed since my upgrade.

Thanks! :)
