The flip side with the heat is that I can’t help but feel I’m introducing another failure mode into my heating system with an internet connected smart thermostat which is a whole lot more of a problem in a sub freezing area than forgetting to turn the thermostat down.

You're not wrong - you are introducing complexity here, and you need to be aware of the failure modes (and the fallback paths available to you).
