#Solarlife ### Solarlife
This is a simple approach to read, parse and pass data from cheap solar charge controllers like Lumiax and Volt to MQTT broker. This is a simple approach to read, parse and pass data from cheap solar charge controllers like Lumiax and Volt to MQTT broker.
You can pass data to home automation software like Home Assistant, Openhab and others. You can pass data to home automation software like Home Assistant, Openhab and others.
Parameters that you will be able to get are for example: Parameters that you will be able to get are for example:
-battery voltage - battery voltage
-battery current - battery current
-battery power - battery power
-battery percentage capability - battery percentage capability
-solar voltage - solar voltage
-solar current - solar current
-solar power - solar power
-load voltage - load voltage
-load current - load current
-load power - load power
-and many more... - and many more...
