I purchased the Mira module from Vegatouch directly and installed it myself. Very easy to do and it allows me to control everything the Firefly panels control on my smartphone. Cost was about $550 so it is not cheap. There is also a different module that will allow you to control everything while away from the coach as long as it has an internet connection and the cost goes up to over $800.
Really didn’t need it but I am a gadget guy plus I can mess with my wife when she turns on the lights or the fan and I can turn them off without her knowing it.
