Learn about Sunblock and how to change settings
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 👁 Sunblock icon
appears on your Nest thermostat's display and on the Nest app’s thermostat screen.

Sunblock uses the Nest thermostat's built-in light sensor to track the sun’s patterns and its temperature sensors to detect the heat spikes that occur in direct sunlight. If your thermostat is connected to Wi-Fi, it’ll also take into account sunrise and sunset time. Sunblock then uses all this information to set your Nest thermostat to the correct temperature whenever it’s in direct sunlight.
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 👁 Sunblock icon
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.
