Where Does Nest Store Thermostat History?
Where the Google Home and Nest apps keep thermostat history on Android and iPhone devices. Full paths are listed below.
Last updated
Nest thermostats report to Google cloud under your home. The phone shows temperature, schedules, and history from that account. Hardware keeps running its schedule even with the app deleted.
Moves are login affairs. Same Google account, same home structure. Exact cache names vary by Google Home versus Nest app builds. Keep the thermostat online during swaps. Gaps from WiFi outages are hardware gaps. No phone restore can fill hours the thermostat never uploaded. Check the in app storage readout when sizes look wrong on different releases.

Frequently asked questions
How do I move Nest thermostats to a new phone?
Schedules, history, and home members follow your Google account home. Sign in on the new phone with the same login. The thermostat keeps its own schedule on hardware. Verify the home name before wiping, since a second home with a similar name splits devices.
Does Nest back up energy history?
Yes, in the cloud account for the covered window. The phone holds login and cache. Energy history rebuilds after sign in. Export key reports from the web home for permanent files, since the phone never holds the master copy.
