# TeslaPowerwall Binding

This binding enables the capture of key data from a Tesla Powerwall 2 into openHAB.

## Supported Things

- `powerwall` Tesla Powerwall 2

## Discovery

The binding does not support auto discovery.

## Thing Configuration

As a minimum, the hostname is needed:

- hostname - The hostname of the Tesla Powerwall 2. Defaults to powerwall to avoid SSL certificate issues
- email - the email of the local account on the Powerwall that the installer provided
- password - the password of the local account on the Powerwall that the installer provided
- refresh - The frequency with which to refresh information from the Tesla Powerwall2 specified in seconds. Defaults to 10 seconds.
