Raspberry PI3 Model B
Getting startetd on a project for remotely controling and monitoring solar and generator powered off grid cabin. Aiming to monitor indoor and outdoor temperature, remotely start and stop a Honda EU30is AC power generator and monitoring voltage on a 12 volt 1200Ah battery bank.
I think I have figured out hardware components for controling start eninge and choke for the power generator, but need hardware advice on the voltage monitoring on the battery bank. The voltage will vary from 11,5V-15.5V, depending on State of Charge and charge voltage from solar panels and generator.
Can anybody advice on necessary hardware, setup and code?
