It shouldn’t. My electric company offers rebates and discounts on any approved smart thermostat, and my heat isn’t even through them. My Honeywell one ended up costing me $50 because of the rebate.

It’s a state-wide thing for participating utility providers, at lest here. They had about 20 models on the shared store (no markup as far as I could tell, but not really a deal either) or provided a list of models that would qualify which contained dozens upon dozens of models.

It’s not just that one single one that has rebates/discounts. That would be silly because those are some of the most expensive.

I hope you went investigating and found a good discount on a smart thermostat for yourself as well.
