I've been able to get MySensors working with HomeGenie using the MQTT gateway. It doesn't have two-way communication or software-based pairing yet, but I'll work on those in the future.
@evb Still haven't had a chance to look at your PR, sorry.
Yes, the database tends to grow I have about 80MB after a year of use. Just added a function to delete all messages older than, say, a year.
I can nothing say about OpenHAB or PiDome but:
Started!
0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
0;0;3;0;9;version mismatch
0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
0;0;3;0;9;version mismatch
Does not look good, it seems an error from the gateway.
