Worst price ever. Do not waste your time II purchased two of these units. I had them professionally installed. Both units keep loosing the wifi signal. This is very annoying when trying to manage the heat from the app when not home. In order to re-connect the wifi , I must detach the unit take out the battery’s and re-install them. The units do not allow me to connect to wi-fi from the menu option on the unit. This is a very frustrating unit and 50% of the time it is off line. I cannot get the ap to switch modes from heat to cool. No options given on ap. No product support.

I managed to get this working with my old brivis gas heating unit. This thermostat need C wire for gas heating.
Old thermostat had only two wires. But the heater unit had C wire built-in which I rewired to connect to this thermostat to make it work.
Setup is very straightforward. It’s being one month since I installed and working perfectly.
Happy with thr product so far.
Note that this is a US product and it has US units and location/ weather information is only related to US or Canada.
But I use Alexa and Google Home to align with my location in AU.

Was looking for a thermostat that has no need for c-wire and has a fan-circulate function, I was searching for Honeywell thermostat but stumble upon this Emerson model while looking, this model fits the bill. I was hoping it qualifies for rebate from utilities but it was not, that is not a deal breaker. The setup was very easy, it does occasionally go offline and disconnect from my router, I resolved that by setting a longer DHCP lease time. After almost two months using it, I am very satisfy with its performance. We’ll see how long the battery will last before it needs changing.

Very very pleased at ease of installation. It started working right away and the ability to control with the phone app while away from the house is just spot-on and fantastic. Very good software and integration ability. Plus the alerts of high humidity and other texts I get get are right to the point and superb. I love this device.

This thermostat is very uncomplicated, but does everything a person should want out of a smart thermostat.
You can pay hundreds for other smart thermostats but none will heat/cool you home better than this Sensi Lite.
The app interface is clean and easy to understand. You can set multiple heat/cool scenarios and activate whichever one needed at the tiime.
One feature that I like in particular is the “Early Start” that will start heat/cool early to achieve your target temperature at the specified time.
For many people who do not have the C-Wire, this thermostat will work perfectly without it. No need to worry yourself and suffer sleepless nights over C-Wire. With or WITHOUT C-Wire this thermostat will do the job for you. Enjoy your sleep with no C-wire nightmares.
I have owned other smart thermostats and some (more expensive than this) have had unreliable connections to wifi. They would be offline as often as ONLIINE. This is very annoying when you want to check the temperature or wish to change settings when you’re away from home.
The Sensi Lite has been ROCK SOLID in its’ online connection. In the months since installation, I have never, even ONCE, observed it being Offline.
I have recommended this to other family members.
If you want to keep your home heated or cooled to a specific range of temperature and don’t want to worry if you will freeze or boil in your home due to a rogue thermostat, then the Sensi Lite is for you.
Check around and you will find almost all other smart thermosts to be MUCH more expensive than the Sensi.
This is reasonably priced and will do a great job for you.
UPDATE: After 2 months of use, the touch sceen on the thermostat croaked, so I was only able to adjust temperature in the app. I purchased this a “Used: Like New”, but as you may know you’re out of luck after 30 days. Fortunately, Amazon gave me a grace period and agreed to refund. But, don’t count on a refund past 30 days.
I repurchased this SAME thermosat, but NEW this time an added a 36 month warrnty, to be safe.
I am still sold on this thermosat, but anything can malfunction, so I don’t believe I’d buy this thermostat as refurbished. I would buy this NEW.

I’ve had this Sensi light thermostat for two months now and it has worked perfectly. Easy to install myself, simple interface and a convenient app to control remotely.
I tried other smart thermostats such as the ecobee and Nest, but they would not work without the C wire. This Sensi(though not as feature packed as Ecobee and Nest) works well and maintains stable WiFi connection and even shows battery status. I would recommend.

The only thing missing from this thermostat’s app is an “away” mode – if you’re using it for a vacation home, you just have to tap the temp down to 52 or whatever when you leave. No big deal.
Other than that, the app works great and comes up quickly. Much faster than the Nest thermo it’s replacing, which I hated – the app is a complicated mess, the “automatic” occupancy detection was worse than useless (it liked to randomly detect people and turn up the temp when no one was there).
Great, simple, remotely accessible thermostat. Let’s hope the app developer sticks around.
