Hi, just an update to this. Thanks to this Community forum I have managed to get my devices to work. All the answers are in this great forum, it just takes the patience to read it through. So to answer my own question - the unhandled commands can be handled by creating a “device handler” for the unsupported Fibaro Dimmer 2 device and then altering the code (in my case a single digit) to get it to function the way I needed it. It’s not as scary as it sounds - all the help is over in this thread, so apologies for my newbee question above, and good luck to others that have this experience. Fibaro 2 Dimmer (212 not 211)
