    Meh Review by James

    For what this one does (or doesn't do), get the Ecobee 4. It's nice to have the sensors in multiple rooms and areas around the house to monitor the system, but this "lite" version just makes it a typical thermostat that you can change the temp with using your phone. For more advanced functionality, you have the 4. I wish it was more intuitive to be honest, and I wish the sensors were better quality. I've had one replaced already, and the others aren't up to the minute with regard to whether or not people are in the house. I find the functionality to be a little ridget, and it's not yet set up for real life situations that I'd like it to deal with and report. For example, I'd like to have different schedules based on season and current weather. Here in Galveston it's been 45 on one day, 80 the next, 50 at night, 70 during the day...all over the map. If I could program different programs for different temperatures and different HUMIDITY levels, this thing would be POWERFUL for me. It doesn't which sucks. Hoping it's on its way soon! Until then, I can live with this. This feature I'm talking about for ALL ecobee models would also make these units more efficient in resource use and cost.
