Review: Fantastic deal for $$, EASY to DIY install w/ great video & app instructions. - I am impressed. First of all, watch the installation video in the item listing in desertcart. It is the first video for this Sensi Lite Smart Thermostat and it could not be anymore thorough than it is. If you want step by step it is that and logical. Then the app itself does the same thing, step by step as well. These folks actually cover all the bases. I know a lot about a lot of this but not AC and heating. It went off without a hitch, I have an old 4 wire system with no C wire and what is really cool is BEFORE YOU EVEN BUY you can d/l the app, go to the step as if you are installing a new one, go where you identify the wires on your old thermostat and it will tell you if it will work for you if you are not sure. I had this thing on, up, and connected to wifi and running in about 10-15 minutes, no issues. The only thing that concerned me was I was reading reviews before buying it and some people complained about it losing connectivity frequently. Only 3 minutes after installing that happened one time, and as I was reading the re-connect instructions it prompts you to, then it reconnected on its own before I could do it. For all I know that could have been my wifi burping, it does sometimes. >>IF<< I have that as a recurring issue I will be returning it because my router has plenty of reach and several devices further from it than this thermostat never lose connection. We shall see. I am just trying to give a full picture, I have no complaints but that was the primary reasonable one I saw in the negative reviews. So far I love the thing, the display is very cool, most of the time I will be bumping it manually walking by and that is a piece of cake. I have old eyes and appreciate the large numbers on the display too. I also like I can adjust it remotely from 4 states over as well. Honestly if you just want a remote app and basic functions with a schedule (I won't use) I don't know about all these others that cost way more why you would buy one of those. It is also nice looking. Oh yeah, it works on Alexa and other voice control things I also do not use. I think you get a lot of bang for the buck on this.
Review: The best thermostat I've ever used - it's a very capable thermostat with all the modern features including geofencing which can optionally setback your thermostat when you are more than 3 mile from the house. It's a very attractive and easy to set up but don't forget to install the batteries even if you use a "C" wire. WiFi won't set up without the included batteries

## Questions & Answers

**Q: How does the auto changeover work? can i set it to keep the temp between 65 and 74 degrees and it turns a/c and heat on as necessary?**
A: Yes I wasn't sure how it would work.  I have my account set to 78.  AC came on when it go too hot.  Hope this helps.

**Q: Hi. My old thermostat has the red wire connect to RH which then jumps to RC. With the Sensi lite, do I just attached the red wire to R? Thank you.**
A: Sensi claims there is an internal jumper which means you only have to connect the red wire which now goes to RH. However, I had to pigtail the red wire and connect to both RH and RC

**Q: Will this thermostat work on a split unit meaning natural gas heat**
A: It works on my natural gas central unit (if you need emergency heat then no this touch lite will not work for you)

**Q: Does this have a child lock?**
A: Yes, it’s called Lock Thermostat Display. It’s located in the system settings.

### ⭐⭐⭐⭐⭐ The best thermostat I've ever used

### ⭐ Poor connectivity
*by B***D on July 22, 2023*

I have a home that was built in 2006 and I work in a technical field (engineer) so I am familiar with troubleshooting hardware/software problems. Anyway, my problems with this unit started immediately. During installation, one is supposed to note the letter codes that the existing thermostat is connected to so that the new thermostat can be notified (via wifi and on app on your phone) how to program its terminals to match the original thermostat's functionality. Unfortunately, my existing wire connection was not recognized as being valid by the app (even though my home is relatively new, has a C wire and works properly with the original controller). I didn't let the this deter to me as I was sure I could fine a setup that would work through a little trial/error and voltage measurement. I was able to program my thermostat the first time without any issues; however, the setup I entered didn't work (system produced heat when it should have been cold), so I tried to reprogram the thermostat for a 2nd try. When I searched for my wifi network on the app, I was informed that no networks could be found, which was strange since all my other devices (computers, tablets, TVs, etc) had no issues connecting to my wifi. No problem I thought because I was given the option of entering the name of a network manually, which I did. After entering the name I was asked to enter the network's password twice, which is also strange since double entry is typically required for setting up online accounts, but not for connecting to your own wifi. Anyway, I entered the password twice and things seemed to be okay for a short time, but then the app kept informing me that it was losing its connection to the thermostat. I put the thermostat in "setup" mode by pressing the mode button for 4 seconds, but the thermostat would only stay in setup mode for a few seconds, and whenever it popped out of setup mode, the app would lose its connection again. What was really frustrating is that every time I tried to change the setup, I had to enter the network name and the password twice, which is pretty dumb for a "smart" device! I fought the system for about 2 hours and I was finally able to get another setup programmed, but that one didn't work either. At this point I decided I was done fighting the thing and I returned it. Again, I'm a competent technical person and my heat pump is relatively new and in good working condition. If I can't get it working smoothly, I don't think many others will be able to either. Perhaps I just had a lemon, but my advice is to steer clear of this finicky little monster.
