SMA Solar


The SMA Solar integration will poll a SMA (US) solar inverter, energy meter or battery inverter and present the values as sensors in Home Assistant.

The integration uses the web interface of the device. Before you start, make sure you are able to connect to the solar inverter from your favorite web browser.

Configuration

Adding SMA Solar to your Home Assistant instance can be done via the user interface, by using this My button:

Manual configuration steps

Sensors

The SMA WebConnect module supports a wide variety of sensors, but not all of these have been mapped in the pysma library. Currently available sensors can be found below. Feel free to submit additional sensors to be added as standard sensors to the pysma library.
