so you want to have the temp go up or down based on song selection?
I didn’t know that.This isn't as strange a question as some of you think. Ecobee4 can already play music/podcasts etc. using Alexa. Sound quality is reputable garbage though.

I have an Ecobee, but one without Alexa. I think it is the Ecobee 3 lite.
While none of the smoke detectors support AirPlay 2, the new Ecobee (the one with glass front) has Bluetooth so you could stream audio from other devices.
As for people criticizing OP for wanting to stream audio from thermostat, I think it's fine for non-music contents like audiobooks and podcasts.
