[Shop-talk] Smart thermostat ?

[David Cole]

I'm looking to upgrade the thermostat in my new-to-me home.   They claim to
reduce heating and cooling costs.

What brands have the list members used with success?  Lots of different
choices out there for programmable units .  7 day, 5-1-1, 5-2, wifi units,
self learning, brands, etc.

The Honeywell units seem to be common at the local big box stores.  Any good?

For hvac I have a heat pump.  American Standard 4 Ton split unit

Thanks
