Setting up a schedule is easy and convenient. It’s nice that you can change the temperature any time from the app. Say on a cold night you need more heat, just grab your phone and crank it up. Or if you’re in the middle of a personal summer you can adjust the heat/air from whatever you are in the house. Mostly I enjoy the scheduling because I make sure I’m not using as much energy when I’m not at home. And it has brought down my gas and electric bill.

A ver decent upgrade
My new Sensei was installed through our local utility service. As a senior, I was reluctant at first due to the connection to Wi-Fi and app, but after I learn to set up schedules and control the temperature through my eye through my cell phone it was a breeze. The Sensi thermometer also changed the performance of my furnace, making it more quick to react when you reset the temperature best thermostat I’ve had in 20 years. It looks more modern than the others also.

Best thermostat I've ever had
This thermostat was installed about 6 months ago. It works perfectly. I get messages on my phone with any issues...high humidity, etc. it's easy to read, make selections and trust.
From Sensi
Multiple zones, three thermostats.
We had our entire HVAC unit replaced and the contractor used the Sensi smart thermostats. We have three zones in the house and are able to access and manage the system through the Sensi app. My only beef is the ability to connect via 5mhz or 2.4mhz as most modern routers automatically assign ip address based upon signal. Easy enough to make the change in the router but would be nice not to have to. Highly recommend these thermostats.
From Sensi
Easy to install and works great!
I installed mine about 9 months ago and it works great. With the app it is easy to change the temperature in the house just before we get home. If we forget to turn the heat down before we leave the house, we can use the app to turn it down. We joined the flex program with Puget Sound Energy and don't even notice when it gets turned down a few degrees.

Great features!
I bought this 12 months ago and I’m so happy that I did! Even as an older woman that’s not very techy I was able to figure out all his functions and features easily. I love all the smart features that save energy and It is so convenient when I’m away from home to set the thermostat with one little touch on my phone. I love it!
From Sensi
Best smart thermostat!
We have 2 homes, with a total of 3 a/c units. We’ve had other smart thermostats on each of the 3 units. Each of Those other thermostats were troublesome, undependable, constantly offline, and difficult to reconnect to WiFi. All 3 of our Sensi Smart Thermostats are just the opposite - easy to use, easy to reconnect after the few times they’ve been offline. I highly recommend Sensi!
From Sensi
Great features
I received my thermostat a little over a year ago through my energy provider and it has been a great addition to our home I love the WiFi capability and how I’m able to control it from my phone and I also love how it send alerts about high humidity overall the product is a great investment
From Sensi
Great Thermostat
I have had this thermostat for over a year and I love it. It is convenient because I can control it using my mobile device or voice activation Alexa to control it. I used to hate getting up out a cold bed but I can turn the thermostat to an optimal temperature before I even get out the bed.
From Sensi
Great features and very simple to use.
I purchased it 6 months ago and really appreciate the simplicity of operation. We are gone for a period of time and are able to keep track of the temperature and change the settings on my smart phone.
