ecobee3 Smart Thermostat & 3 Room Sensors, Compatible with Alexa (Renewed)

I bought a 100 year old house in which the dumb thermostat was placed right next to some leaky sash duplex windows. There was no way to just set the thermostat and forget it. As the Texas heat rose during the day the thermostat location rose along with it. If I didn't turn up the thermostat, the AC would simply run all day and freeze out the rest of the house. So three or four times a day I would turn up the thermostat to turn off the AC unit. I actually talked to someone about moving the thermostat, but fortunately he declined.Fast forward to receiving a mailer from a warehouse club with the Ecobee thermostat and sensor. As I read up on this device, I realized this could potentially solve my problem! I watched an online video of the installation, and checked my wiring to discover that I indeed had a C-wire (which made the install easier). I ended up buying the Ecobee3 with 3 sensors from Amazon. Although I watched the installation video, I was still nervous about the install. Semi-pro tip: Take a clear picture of your current wiring before you take it apart. This will help you rewire with the Ecobee. The installation was actually pretty simple, and I did all of it after watching one video. Still, there is always that trepidation where you worry if 1) you did everything correctly and 2) is it going to work?Ecobee has done an excellent job with their guided software interface. I just followed their prompts and created an online account etc. I did have a little difficulty figuring out the online interface and how to get the unit to follow the schedule I created. The schedule I created allowed my to choose the temperature for AM and PM and to select the sensors I wanted the thermostat to use. Semi-pro tip #2: If it says "xx and hold" or "Home and hold" under the temperature, you aren't following your schedule. You are overriding your schedule. Click on the "X" on the "on hold" notice and the thermostat will follow your schedule.I am no longer chained to the thermostat sensor by the leaking window. The schedule I created allowed me to focus on the sensors in the bedroom, TV room and kitchen. I can now literally set the thermostat and forget it. I wish I had done this sooner.

Powered up but would not turn any of the units on. Wires were checked and rechecked. I ended up returning and ordering a new unit that was not a reburb.

Do not buy refurbished!!! Everything has to be reset with ecobee and not easy to set up!!!

I love it, it controls the temperarure better than the standard, controls separated rooms, the schedule is easy to setup.
