How to read your Nest thermostat’s Energy History
Your Nest thermostat’s Energy History shows you how often and for how long your system has run, so that you can make smart choices about your schedule and temperature preferences.
Your thermostat’s Energy History is a detailed summary that covers the last 10 days. You can view it on your thermostat or with the Nest app.
Note: To see Energy History, your thermostat must be connected to Wi-Fi and be added to the Nest app.
On your thermostat
You can find your Energy History by selecting Energy in the Nest thermostat's Quick View menu.

Domestic hot water won't be shown in your Energy History
If you have a 3rd-generation Nest Learning Thermostat, it can also control your domestic hot water. However, you won't see the times when your domestic hot water was on and using energy in your Energy History. The Nest thermostat can still help you save though – you can create a personalised schedule to control exactly when your hot water is on, and Home/Away Assist will help by turning off your hot water when you're away for extended periods, such as when you're on holiday.
How OpenTherm can affect your Energy History
If you have a 3rd generation Nest Learning Thermostat installed with an OpenTherm-compatible boiler, when True Radiant is enabled, you might see long heating times in your Energy History and Home Report. As your 3rd gen Nest Learning Thermostat will tell your OpenTherm-compatible boiler how to modulate when True Radiant is enabled, your heating can run for long periods of time – but the heating water will be at a lower temperature to control your home's temperature more precisely. This type of heating control can be a more efficient way of keeping you comfortable.
