my first deal posting, so be gentle (searched and didn't find this posted yet)
Microsoft store has the Glas thermostat by Johnson Controls on sale for $129 (MSRP $319)
if you are looking for a new thermostat, this seems like a good deal. has a beautiful oled touchscreen. it used to have Cortana voice controls but my understanding they took that away in a software upgrade (but seems to work with Alexa and Google home)
seems like the lowest price I could find ever for a new one.
