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 Wi-Fi module. The Wi-Fi module requires a username and password for authentication where the ethernet module does not.
To enable this sensor, add the following lines to your
# Example configuration.yaml entry sensor: - platform: saj host: IP_ADDRESS_OF_DEVICE
Username for logging in to SAJ Solar Inverter (only used when type is ‘wifi’ but can be skipped if the inverter still has the default credentials set: admin/admin)
Sensors available in the library:
|current_power||W||Current power generated by the inverter.|
|today_yield||kWh||Power yield for today.|
|today_time||h||Inverter’s running time for today.|
|today_max_current||W||Maximum current power for today. (only for connection via ethernet module)|
|total_yield||kWh||Total kWh generated to date.|
|total_time||h||Total running time of the inverter.|
|total_co2_reduced||kg||Total CO2 in kg reduced.|
|temperature||°C||Temperature of the inverter.|
|state||N/A||Live state of the inverter.|
