Common Sensi Smart Thermostat Problems and How to Fix Them
1. No Wi-Fi Connection On Sensi Thermostat
It is not unusual to see the thermostat going offline from time to time. When this happens, an error message pops up, reading, “thermostat is offline,” showing that there is something wrong with your network. This can sometimes happen due to low batteries on the thermostat or poor network signals preventing the device from connecting smoothly with the mobile app. Here’s how to fix this issue.
Replace batteries if low:
To fix this problem, first, check that the batteries on your thermostat are okay. If you notice the battery indicator in the top right corner of your Sensi thermostat is half-full, you might need to replace the batteries. When the batteries go low, the Wi-Fi radio turns off to preserve power, hence sending your thermostat offline.
Fix network problems:
If your batteries are okay, then you want to check your internet connection to ensure it works properly. A simple way to do this is to browse on a mobile phone connected to the Wi-Fi network.
If the fault is from the internet connection, restart your router to fix the issue. You may also consider moving your router closer to the thermostat if the distance between them is much. That will help improve signal strength and help your device connect better to your mobile app.
Check system compatibility:
Does your Wi-Fi turn off after about two hours of turning on the device? If so, chances are the network issue might be due to system compatibility or a c-wire issue. Users who have a cool-only, heat-only, or heat pump system would need a common wire (c-wire) to maintain a Wi-Fi connection.

2. Sensi Thermostat App Not Working
This is another common problem Sensi smart thermostat users face. The app may suddenly stop working, meaning you can’t control your device remotely at the time. This issue can happen because of a minor bug in the app, and it is not something difficult to fix at all.
To fix this, go to the app settings section on your phone and find the Sensi app. Once you find the app, click on it and then go to the storage option. There, you will see an option to either clear the app cache or clear all app data.
First, try to clear the app cache and then open the app again to see if that resolves the issue. If it doesn’t, then you will need to clear all the app data. That should fix the ‘Sensi Thermostat not connecting to the Sensi app bug’.
3. Sensi Thermostat Display Button Not Working
This is a common problem with Sensi Thermostat (the display button not working) and the good news is you can easily fix it without calling an HVAC expert.
To fix this, first, check if you have not accidentally enabled the keypad lock feature on the thermostat. Some users enable this option without even knowing it.
When the feature is enabled, your keypad won’t function correctly until you disable it. So, before you assume something is wrong with your thermostat or its keypad, check to see if this feature is enabled so you can turn it off.
However, if you try that and the display buttons are still not responding, you might need to reset your thermostat. Though that is always the last option, you can be sure it will fix the issue for you. To reset your Sensi smart thermostat, simply remove the unit from the mount and remove the batteries.
The screen will go blank after removing the batteries. Now wait for about 5 seconds and then put them back in. Put back the unit too and wait for a few minutes for the thermostat to reset. The display buttons should be back and active again now.
Note: Resetting your thermostat may erase all previous settings. So be sure to reprogram it after performing a factory reset.
From Wi-Fi connection issues to display buttons not responding, Sensi smart thermostat users may face any of these problems. However, most of the problems are things that you can fix yourself.
If your thermostat won’t connect to Wi-Fi, you might need to replace the batteries, check system compatibility, or restart your router.
If your Sensi thermostat display button doesn’t respond, you might need to disable the keypad lock feature. We covered more details about this and other issues in this post, hope it helps!
And lastly, if your thermostat still doesn’t work after trying some troubleshooting tips, contact Sensi support or get an HVAC expert to check it.
We strongly advise that you don’t handle any electrical problems yourself if you have no prior experience.
