Hi is the rpi B+ compatable with HomeGenie?
All my sensors and switches etc work fine in my rev 2 rpi. When i switch the breadboard header to rpi B+ rev3 things act strange or just dont work. The IR and DHT11 work, as does the csi camera when i2c is disabled but doesn't when its enabled. But the mcp23017 refuses to work even when i2c is enabled and working. I get this error message
"18:27:45.724   Runtime.Error   CR: Board revision 3 is not supported   71   HomeAutomation.HomeGenie.Automation"
I thought the gpio was backwards compatable i'm confused.

I also ran into another issue when setting up my rpi B+. Which stops the csi camera working when i2c is enabled. To save people time if they run into the same problem there is a fix discussed here:
