If your Google Nest thermostat is on the Nest Stand and it's not switching between the Eco Temperature and heating when you think it should, there are some simple fixes.
In general, it's especially important that your thermostat is located on a flat surface at the recommended height between 0.75 and 1 meter above the floor.
Before troubleshooting
If your thermostat is set to switch between Eco Temperature and heating automatically when you leave and come home, it will wait a while after everyone leaves before switching to Eco Temperature.
How long your thermostat will wait depends on where it's installed and what it's learned about your home and your habits. In some cases, the delay can be a couple of hours, so be patient.
If your thermostat hasn't switched to Eco Temperature after a few hours, you can manually set your thermostat to Eco Temperature if needed, then follow the steps below to troubleshoot.
Note: The troubleshooting steps in this article generally apply if you don't have a phone helping with presence sensing. If your phone is helping with presence sensing and you're having trouble, troubleshoot automatic switching for your thermostat.
Troubleshooting steps
1. Make sure that automatic switching to Away uses Eco Temperature
|
Presence-based automations (Google Home app) or Home/Away Assist (Nest app) settings may have been changed, preventing your thermostat from switching to Eco Temperature. Check that switching to Eco Temperature is enabled with the app or on the thermostat. |

2. Check the Nest Stand location
Your thermostat's location impacts how well it automatically switches between Eco Temperature and heating based on whether you're home.
First, check the location of your Nest Stand to make sure your thermostat can sense activity. Adjust its placement if needed.
Important:
-
You should only move your Nest thermostat if necessary.
-
Even if you've moved it a few inches or to a new room, it will need to re-learn in its new location.
-
If you've adjusted its location, you should reset what your thermostat has learned about your home and your habits.
Tips:
-
Your thermostat should be placed between 0.75 and 1 meter above the floor.
-
Placing your thermostat too far back on a shelf or table can block its sensors, preventing it from accurately sensing if you're home or away. Move it closer to the edge to try to fix the issue.
-
Placing your Nest Stand on a low surface may cause the thermostat to detect pets, keeping it from switching to Eco Temperature. Move it to a higher location to try to fix the issue.

3. Check that Routines aren't adjusting the thermostat
Occasionally, Google Home or Assistant Routines can prevent your thermostat from switching to Eco Temperature.
If you suspect a Routine is adjusting the thermostat, check its recent activity:
-
Open the Google Home app
.
-
Tap Activity
.
Tip: To check your Personal Routines, go to My Activity. Other home members might also need to check their Personal Routines. You must have Web & App Activity turned on.
Learn how to create and manage Routines in Google Home app.
Change the settings of a Routine:
-
Open the Google Home app
-
Tap Automations
the name of the Routine.

|
Normally, you only need to reset thermostat learning if you recently changed your habits or moved your thermostat to a new spot. After you reset what your thermostat has learned, it will relearn your habits and temperature preferences. It will be ready to automatically switch to Eco Temperature again in a few days. Follow these steps to reset Away:

5. Add a phone to help with automatic switching to Home and Away
Presence-based automations and Home/Away Assist use your phone's location to let your thermostat know when you're home and when you've left. Phone location can help your thermostat switch between Eco Temperature and heating without your thermostat having to sense you.
