Nice to have articles like this to break down the features of each thermostat. I wasn't interested in Nest's learning feature, I was put off by the poor reviews of the Lyric's geofencing performance, and wanted a do-it-yourself installation. I ended up making the same choice you did with the ecobee3. I've been totally satisfied with my purchase and would go this route again. I love the remote sensors (though you may not want to confuse people with the word "zone," which implies independent HVAC response for each section) and the data collection ecobee offers!
The remote sensors and temperature averaging make Ecobee3 the best hands down. Innovation aside the company, their tech support, and customer relations make Ecobee the clear choice for the discerning consumer who wants an outstanding HVAC solution.
I think you have it right. The ecobee3 is so awesome for keeping multiple room the correct temperature. I found that I have 5 degree temperature variations in my house. This thermostat has fixed my problem, and I save big money and the save the world with green energy savings. You can have your cake and eate it too.
I was about to go out and buy a Nest but decided I would do some research first. I had no idea there were actually more competitors in the smart thermostat arena and found out about the Ecobee3 during this time. The remote sensors are what sealed the deal for me. The temperature averaging has really helped keep my bedrooms from being too cold in the winter, eliminating the need for space heaters. I expect similar results in the summer for the heat.
From my experience, there has been no comparison to the ecobee. The amount of data given to the consumer allows the consumer to actually make intelligent choices about heating and cooling, while providing the convenience and comfort of remote access. Absolutely love my ecobee!
I've had the ecobee3 since it came out and it is hands down one of the best purchases I have ever made. The remote sensors actually help to make intelligent comfort decisions and the data you get out of HomeIQ is very informative.
