My wife refuses to use the HA since she says Alexa doesn't understand her!
Main issue which turned her off was replacing 3 hallway light switches with an Insteon micro switch. I had to have the Sparky basically disconnect one of the switches as it caused the Insteon to have issues. The Insteon is supposed to be able to detect if the switch is powered or not so you can control the switch either via the wall switch itself or via the Insteon app and hence Alexa. Could be a wiring issue but the switch does nothing at the moment which annoys my wife. So without talking to Alexa she could not turn the lights on or off :-(
In the end I gave up and bought an Insteon remote (!) which I mount where of the switches is. So she can turn the lights on an off using the remote which surprisingly if what she could do with the original wall switch. To be fare the remote can control up to 3 Insteon devices and I do have an Insteon smart wall plug which the remote can also control.
HA is a work in progress for me. I have a Harmony Elite (?) which one day I will install and plan to control the HT with it. I can just imagine what my wife will think when she can't turn on the TV without talking to Alexa.
