Solar voltage monitoring

Hello everyone.

Is there hardware out there I cannot use to monitor the voltage of a 12v battery in my garden shed which also can been seen via the app. I have a raspberry pi in the she’s operating relays to 12v lighting.

I have garden lighting set up as scheduled events. This is powered by a solar set up . However with the amount of lights that I am planning on connecting and still a weak sun, I would like to monitor the voltage of my battery remotely.

Thank you.

Simplest one, voltage divider to one of the pins :slight_smile:
