Hi Neil, no worries for these 'problems', it is expected as you are developing the plugin !
first problem you are right, I change the device and saved, error message gone.
problem two remains, even with AC turned on, see below:

About the behaviour, I would go with point 2, I would expect Indigo to reflect the state of the AC at every moment, like the app does, so there is no discrepancies. And it will also be useful if Indigo is informed that a changed occur because someone changed a parameter using the app or the remote. Point 3 also works for me, I don't see why someone would prefer point 1 though...
