    Great Thermostat with a clean look.
  

*by J***N on Reviewed in the United States on June 29, 2017*

This thermostat paired easily with my Z-Wave.Me usb stick connected to my Raspberry Pi3 running Home Assistant (0.45.1). I am able to remotely control and monitor the thermostat. I have not setup a schedule or any home/away automations yet but I have confidence the thermostat will do what it is commanded to.I did not have a live "C" wire at my old mercury thermostat, but there was a spare wire in the bundle. I climbed into the attic to look at my carrier air handler (CAUTION - TURN POWER OFF FIRST). The other end of this spare wire was available there which, with some googling for wiring info on my unit, I hooked into the "C" wire of the air handler. I went back down to the thermostat wires after switching power back on and confirmed 24v between the "R" and "C" wires with my multimeter. This will power the CT100 Plus without the need for batteries. Powered the Air Conditioner off at the panel one more time. Wired in the new thermostat. Threw the breaker back on and it fired right up with a little beep.Went into Home Assistant and put it in inclusion mode. Walked back to the thermostat to put it in pair mode. In about 10 seconds it showed that it was linked up. Restarted Home Assistant and I had all the entities related to the thermostat. I grouped them together and made a nice pane to keep it organized (see pic).All in all I'm very happy with this thermostat. The install and pairing were easy once I got my "C" wire squared away. It can run on battery as well so don't let the absence of a "C" wire deter you. In the event that the smarts of your home go down, this thermostat still functions as dumb programmable thermostat. Clean look on the wall with a white backlight when touched, although the touchscreen is not very sensitive once the cover is installed. You shouldn't need to interact with the physical unit once it's up and running though.a couple features I like- temperature AND Humidity sensors- screen can be locked to block unauthorized access- swing temp is adjustable- flexible to multiple HVAC system types- still functions if your smarthome controller goes down- no cloud connectivity- decent size so it should cover up where your old thermostat wasn't painted

    So far, so good.
  

*by T***M on Reviewed in the United States on July 7, 2017*

So far, so good. I have been having trouble with my older z-wave devices but all of my newer "Z-wave Plus" devices are working. Sometimes it does not show the correct temp on my Vera Plus, but I have always been able to control it. Oh, also has humidity display on my Vera UI7 software that seems to be accurate. Looks good too. I'll update this review later if anything changes......I purchased a second one for the bedrooms. I had trouble including it in my Vera Plus UI7 system at first, but then I decided to exclude it and then do a factory reset. After that it included just fine and communicates so far without errors to a controller that is a good 60-70 ft. away. Still a fan...

    Can not return a defective thermostat
  

*by W***S on Reviewed in the United States on December 12, 2017*

I ordered 5 of these thermostats for new construction of my home. They were installed after the return window as contractors had not finished electric/HVAC.  When installed I saw that one unit was a CT100 but a different model from the other 4. This thermostat will not work remotely and the touchscreen does not work either. I have changed batteries twice and had the HVAC technician look as well. It simply does not work. Now I can't return a $100 item that was defective from the box because it was not able to be installed until after the return window.
