Hand Off and Take Back
A heater talks to one phone at a time. Hand Off lets another phone, or another app, take over.
- Hand Off (in More): this phone lets go of the heater and stops reconnecting.
- Take Back: this phone connects again.
The heater keeps running as it was. Handing off never sends a command.
If the app says Held by another phone, open the app on that phone and tap Hand Off there, or close the other app.
Same help as in the app (More → How to use).
