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 Wi-Fi module. The Wi-Fi 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
host: IP_ADDRESS_OF_DEVICE
Configuration Variables
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)
