Example usage

See for a basic usage and tests

Home Assistant

The Home Assistant sma sensor documentation can be found here

This library uses Webconnect. Modbus is not supported

If you can access your SMA via your browser, this might work for you.

If you access your SMA WebConnect via https:// you should set both ssl: true and verify_ssl: false.

Daily usage is not always available from the SMA WebConnect interface. It is possible to get around this by using a utility meter or more recently from the Energy management feature in Home Assistant

How to debug this addon

  1. Ensure you can access your SMA from your browser

To enable detailed logging in Home Assistant, you can add the following to your configuration

  default: info
    homeassistant.components.sma: debug
    pysma: debug

Energy Meter

This library can read the second version of the emnergy meter, there is a seperate Home Assistant OS Addon that could also read older Energy Meters directly. See Energy Meter
