Tesla FleetAPI for Powerwall

[jasonacox]

Tesla's official cloud API for the Powerwall is the FleetAPI. This is the same API used for Tesla vehicles.

Setup FleetAPI

The Powerwall Dashboard and pyPowerwall support this method as well as the local APIs and unofficial Tesla Owners cloud API. Information about setting up FleetAPI is located here: https://github.com/jasonacox/pypowerwall?tab=readme-ov-file#fleetapi-setup---option-2 (reference Tesla onboarding: https://developer.tesla.com/docs/fleet-api/getting-started/what-is-fleet-api)

Cost

Please note, Tesla has announced that they will be charing for using the FleetAPI but those who sign up will get a monthly credit for personal use. However, it seems that their preferred method is the "streaming signals" method for vehicles which does not indicate that it applies to Powerwall. Using their posted rates, data polling would likely exceed the free limit (I estimate $17/mo polling on 5s intervals, but have not confirmed or tested).

The preferred method, which could be zero cost with the credit, is the "Fleet Telemetry" method that streams updates from the vehicle (no mention of Powerwalls) to a telemetry server. This server must have a public internet IP address which may make this more complicated for most home users. However, you can see details here: https://developer.tesla.com/docs/fleet-api/fleet-telemetry - I don't know if this method would ever be available to Powerwall owners, but I'm listed it here for information.
