I actually have never sold my used rigs. My friends children just get really good machines to do their homework on. :lol:
Yes, the new heat works quite well, although I keep a cool home so it doesn't work too hard.
The voice control is limited but the thermostats, which were already here, do respond to my voice, via Amazon's Echo. I can't turn it off/on but I can change the temp with just a voice command. The capabilities continue to grow. I can now make phone calls using the Echo, which annoys the hell out of the dogs since they don't know where the other voice is coming from.
If I can ever find wall plates that look good but aren't made out of metal, wood is my next option, then I will have complete control over the lights. My copper and brass finished wall plates interfere with the WiFi connection so I am not where I want to be.
Btw, satellite (Sirius/XM) radio is now integrated with the Echo system. No commercials and awesome music is a major plus, for me, since I run music throughout the house 24/7. Marantz based audio, coupled with a Synology multimedia server, throughout the house is nearly complete.
