I tried using a Pro Mini 3.3v@8Mhz for the homeduino plugin, but every command came back as ERR unknown_command.
Switching to an Uno 3.3v@16Mhz worked fine with no other changes. Unfortunately only have one pi at the moment, and alrady loving pimatic more than the tellstick.net stuff I used before so slightly reluctant to keep digging at the moment. But figured I’d make a post if anyone else tries the same and fails as I found no hits when searching.
