I had a Braeburn 7205 that worked pretty good. I had also purchased an Emerson Sensi st55 on Amazon, at first thinking I needed two thermostats, because I have two geothermal heat pump systems. I posted on this site that I would like to have only one thermostat running both systems. I got a reply on how to combine the two into one thermostat using relays. I elected to use the Emerson Sensi because it has a larger screen. It works well with my 3 stage setup and gives a usage report that actually shows the usage for the 3rd stage (Aux) as a separate item in the report. Also I like having the cell phone and Alexa features, mostly for showing off to my wife and friends..
