The Maestro Wireless dimmers are non-system dimmers that won't work with the Amazon Echo. If you like the look, then the Radio Ra2 dimmers will work with the Amazon Alexa, as long as you have both a Main Repeater, and a Connect Bridge for the Radio Ra2 system. I would suggest contacting one of our Residential Dealers in your area.
Go to the following "Where To Buy" website:
