We have literally had 2 clients ask about it in the last year. I've had several that automatically bring it up during a consult and then proceed to tell me that they are not interested in it in the slightest. Privacy seems to be their concern. I could fight that battle, but I enough battles to fight.

Until it's very reliable, we won't recommend it. Of the 2 clients that asked about it, one didn't go with us because they were "not sure if they really need a full smart home system." The other had an echo and we could not get alexa to see the Heos amp on the network. And by network, I mean Comcast Gateway. I immediately pointed to the fact that we spoke about installing a proper network during the consult. Short story, both clients were cheap. I'm starting to think that I should weed these clients out as soon as they mention "Alexa" or "Google Home."
