How to control your Nest Thermostat using your Wemo App


You can now control both your Wemo® devices and your Nest Thermostat using the Wemo App.  With your Wemo App, you can control your Nest Thermostat manually setting Home and Away modes, changing Heating and Cooling modes or adjusting the temperature.

Before we start, there are a few requirements that need to be checked:
    
1.  Your Nest Thermostat is installed and working with the Nest App.
2.  Your Wemo devices are set up and working.
3.  You are using Wemo App v1.18 or higher.
4.  You have Wemo Remote Access enabled on your smartphone or tablet.
5.  Your Wemo device is set up to work with your Nest Thermostat.

If you are missing one of these requirements, do not proceed with the setup and use the links below if you need assistance:
 
 
The Nest Thermostat device tile

After connecting your Nest account with your Wemo, any thermostats that are associated with your Nest account will show in your Wemo devices list along with your other Wemo devices.

NOTE:  Custom device icons are not supported for Nest.  

The device tile for your Nest Thermostat can give you basic information about its status:
 
1.  Device Icon:  This shows the current status of the device.  You can see what heat/cool mode it is in along with the current temperature/target temperature.  The icon will change colors if it is heating or cooling at that point in time.

1.  Home:  Home mode is used when you are at the same location as the thermostat.  It is indicated by the button being highlighted green.  When in Home mode the thermostat is on and active.
2.  Away:  Away mode is for when you are not at home and do not want the thermostat running.  The thermostat is still ON but is not actively heating nor cooling.  It is indicated by a grey button.
3.  Off:  You can set the thermostat to completely OFF.  When the thermostat is OFF it will show as OFF in the device tile and there will be no power button to control it.

When the thermostat is set to Home mode the Device Icon will show the operation mode that the thermostat is currently in.  In each mode you will see the temperature the thermostat is set to (Large number) and the current temperature (small number).

3.  Standby:  The status icon will be grey to show it is neither heating nor cooling.
