Dit product is niet geschikt voor gebruik in de EU. Probleem begint al bij het registratie proces, daar loop je vast omdat registratie alleen voor USA en Canada mogelijk is. Het alternatief (Apple home) beschikt niet over alle functies voor optimaal gebruik en functionaliteit. Programma’s (schedules) maken is onmogelijk. Door registratie problemen werkt deze thermostaat (zonder schedules) alleen binnen je eigen netwerk omgeving en niet buitenshuis. (Middels Apple apparatuur geprobeerd het draaiende te krijgen)

So far this thermostat is working very well as a replacement for an old-style analog Honeywell. The touch screen is easy to use, setup and home network integration are a breeze, and it easily connects to Apple Home. The Apple Home app functionality is very basic, but I like having the ability to run automations or use voice commands with Siri. The Sensi app on the other hand has a lot of features, and is well-designed with a pretty intuitive user interface. It’s only been a couple of months but I’m very happy with it thus far. UPDATE: It’s now been over a year. I have had no issues at all. The only time it drops connection from wifi is when the power or internet go out. The app is just amazing. You can do a lot but it’s not clunky or confusing. They just keep making it better and easier to use. One of the best smart home device apps I have ever used. I hardly ever use the touch panel.

I worked in HVAC for some years prior to entering the new field and have installed my fair share of thermostats. Recently purchased a house and it came with an Ecobee 4. Had nothing but issues with it. Would crash randomly and take up to 25 minutes to reboot, and in general does not carry ease of use. Now onto the Sensi touch. Amazingly simple to install and wire, the app even gives you a guide so you can designate what your previous wiring was at the terminals of the thermostat and it will automatically reconfigure and give you a 2-D diagram of positive wire up the Sensi using your existing wiring. Once wired up, I finished registering in the app and was able to control my thermostat remotely on my phone. Both of the app and the thermostat itself are quality, sleek, simple and is incredibly easy to use. I know there are a lot of high tech options out there, but if you are looking for something that is easy to install, reliable, and really offers most of what you would get when spending several hundred dollars on a thermostat for a flat $100. I highly recommend it.

I installed this today by myself. I took a pic of my old thermostat configuration to show you all. Took maybe 15 mins for everything except the WiFi. I followed the instructions on the app which was a very helpful tool. I can't say enough good things about that bc whenever I install a new thermostat I am puzzled when the letters don't matchy matchy. This app took that guesswork out for me. Thank you Emerson. The wifi I was stumped on for a but bc it said my password didn't work. I figured out either me or the app was adding a space at the end of the password... So just be aware of that. This thing works amazing. If it blows up or stops working down the road, I'll update my post but so far, so good. Both the touch screen on the device and the app work great. I love that you can lock the touch screen so your kids can't increase the temperature. Installed my second one in the house where I only had R W G wires. Followed tutorial on changing G to C wire and I got it up and running. Wasn't a problem. Added 10 mins onto the job. Easy peasy.
