I just recently purchased a home and would like to incorporate Smartthings or a similar home automation system into my new home. In my previous home I had a 3M Filtrete thermostat and liked it, but would like something a bit more capable. My home has two complete HVAC systems with two thermostats, two A/C systems, and two gas forced air units.
I am open to all options. Though it seems the most popular are Ecobee, Nest, and Honewyell. My question is two fold. Which system is best for integrating into Smartthings? Which system, if any, works best with two full systems? I realize that I will need two thermostats, but I’m curious if there are any systems intelligent enough to allow the two thermostats to communicate with each other and work in conjunction to work most efficiently.
