I have a unused homecenter v2 module with a raspberry pi compute module. I replaced the pi with homecenter on it with one with openhab. I already installed the velbus binding and snap tcp and it’s online.
The only problem i have is that it don’t connect to the bus, so it don’t find any of my modules. I think that the problem is the link between the network bridge and the module hardware interface. This is serial i think. I also know on which gpio the bus is connected.
I hope that someone can help me with this
I want to use this module because it only requires bus connection and network, like the signum.
Would be usefull to share the gpio connected pins (and how ic-type), maybe serialbus like you suggested.
Quite expensive rpi solution…
yeah, but a yearly renewal of the homecenter license is also expensive
I found this in the config file:
#Overlay UART0 (/dev/ttyAMA0) to pin 14, 15 for Serial FTDI
#Overlay UART1 (/dev/ttyS0) to pin 32, 33 for Velbus connection
You got all you need for openhab connection “/dev/ttyS0”, look here:
Don’t forget to activate serialports in rpi config, look for “Disable Linux serial console”:
However, you can keep the debug serial active. SSH is more common.
The snap “Auto discovery” manual asign mode:
Success with this!
