  title: Tesla Fleet Energy Backup API
  description: 'The energy_sites surface of the Tesla Fleet API. Lets OAuth-authorized partners and owners read

    Powerwall, Solar, and Megapack site state — site info, live status, calendar history, programs —

    and write backup reserve, operation mode (self_consumption, backup, autonomous), storm mode,

    time-of-use settings, and off-grid vehicle charging reserve.


    Authentication uses Tesla Fleet API OAuth 2.0 with the energy_device_data (read) and

    energy_cmds (write) scopes. Third-party applications must register a partner account on the

    Tesla Developer Portal and pair a virtual key with the owner''s account.
