Great plugin. One thing though: I expected it would be possible to ring the bell from Indigo, but this seems not possible. Am I missing something? I could of course wire the relay output parallel to the bell output and use the relay to ring the bell.
about a year ago I had some interaction with Doorbird regarding an API for their chime - it has a library of sounds so could be useful for sounding alerts (not sure if his is the use case you are referring to)...at that point there was no support for this in the Doorbrid API.
