SAJ Solar Inverter


The saj sensor will poll a SAJ solar inverter and present the values as sensors in Home Assistant.

This sensor uses the web interface and to use it, you have to be able to connect to the solar inverter from your favorite web browser.

There is a difference between inverters that are connected via an ethernet module and those connected via a WiFi module. The WiFi module requires a username and password for authentication where the ethernet module does not.

Configuration

To enable this sensor, add the following lines to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  - platform: saj
