Direct sunlight can cause a thermostat’s temperature sensors to heat up, so it may think that the ambient temperature in the room is higher than it actually is. When this happens, your thermostat may not keep your home the temperature that you want, making things uncomfortable for you. Google Nest thermostats use Sunblock to compensate for direct sunlight and keep your home comfortable.
When Sunblock is active, a sun icon appears on your Nest thermostat's display and on the Nest app’s thermostat screen.
Sunblock availability
The Nest Learning Thermostat and Nest Thermostat E can use Sunblock. |

Sunblock isn't available on the Nest Thermostat. |
How sunblock works
How Sunblock decides when to turn on
When you first install the Nest thermostat on your wall, Sunblock will start learning the sun’s patterns in your home. After a few days, Sunblock will be ready to turn on. If it senses that your Nest thermostat is in direct sunlight, Sunblock will automatically activate.
Ambient light isn't enough to trigger Sunblock, so you should only see it if your thermostat is heating up in direct sunlight.
When Sunblock is active, a little shining sun will appear on your Nest thermostat's display, where the Nest Leaf would usually appear. You’ll also see the Sunblock icon when looking at the Nest app.
