I'm looking to buy a new thermostat to integrate into my system. The thing is that I don't really need a lot of the features like learning or wifi. I just need one that I send basic commands. The one feature that I do need is the ability to turn only the fan on for a set time at different periods throughout the day to air out the house. I have a cat and this clears the box smell from the home. I can do the fan via smart apps I just need to make sure that the fan only control is exposed in the UI for the thermo. Any suggestions?
