Such a waste of your time. Get paid up front and let them know that you are not responsible for the Alexa recording everything they say and sending it to Amazon. "Alexa, tell Crestron to recall the evening scene" If she gets it on the first try. I tested one for a month and then threw it in the garbage.

Tell your customer that EVERY SINGLE SERVICE CALL IS NOT WARRANTY AND WILL BE CHARGED. You'll be back many, many times.
