# Fronius Wattpilot Binding

This binding integrates the Fronius Wattpilot EV charging stations (opens new window) through their unofficial WebSocket API, which is also used by the Fronius Solar.Wattpilot app (opens new window).

It should support all Fronius Wattpilot wallboxes and has been tested with the following models:

  • Fronius Wattpilot Home 11J
  • Fronius Wattpilot Home 22J

# Supported Things

  • wattpilot: A Fronius Wattpilot wallbox

# Discovery

The binding implements auto-discovery of Wattpilot wallboxes through mDNS.

If the binding discovered a Wattpilot, it is added to the inbox. After adding it from the inbox, you need to configure the password for accessing the Wattpilot.
