I have that exact setup for control, and there’s 1 thing I want to control, and that’s the start time of warming up in the morning depending on outside temp. It’s less efficient at lower temps so takes longer to provide enough heat, and my house loses heat faster at cooler temps, so needs more heat at those lower temps. I want to say “make it 72 at 8am” not “start at 6am to try to get to 72 at some future time”

I’m also concerned about what happens when their online system stops working. Technically I can program some on the connected unit, but it’s not ideal

Oh, it also can only use the temp from 1 remote thermostat at a time. My last 3rd party one allowed, for instance, the night temp to be the remote in the bedroom and the daytime to be set by the living room remote - Trane doesn’t support that in the schedules at all.
