I'm an Ecobee user as well, what I really want is better vent control room-by-room and I want it integrated into the thermostat. There are companies like Keen selling net-connected vent baffles, but the price is still really prohibitive. Like $1500 to do a house prohibitive. And then it's still not integrated with the thermostat. An Ecobee-compatible vent baffle for $30-$50? That would be a no-brainer.
