Anyone used a smart thermostat? I find that the temperature in the bedrooms seem significantly cooler than at the thermostat itself. Seems like this is causing the ac system to run longer trying to obtain the desired temp at the thermostat due to no vents being anywhere near the thermostat itself(in a hall). Considering the ecobee with room sensors to place in frequented areas of the house but would take any input from anyone with experience with any of the smart thermostats. Thanks in advance!
