SMA Solar
The SMA Solar integration will poll a SMA
Configuration
To add the SMA Solar integration to your Home Assistant instance, use this My button:
If the above My button doesn’t work, you can also perform the following steps manually:
-
Browse to your Home Assistant instance.
-
In the bottom right corner, select the
Add Integration button. -
From the list, select SMA Solar.
-
Follow the instructions on screen to complete the setup.
Supported Devices
Not all inverters, energy meters and batteries from SMA are supported.
The integration uses the device’s web interface (called webconnect). Before you start, make sure you are able to connect to the solar inverter from your favorite web browser. Devices with the ennexos operating system (like the Tripower X series) and all Energy Meters (SMA Energy Meter and SMA Sunny Home Manager) are not supported.
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
