Bought a DFRobot UPS Hat (https://wiki.dfrobot.com/UPS%20HAT%20for%20Raspberry%20Pi%20%20Zero%20%20SKU%3A%20DFR0528) that's arriving tomorrow, to help round out my #HomeAssistant setup for our RV.

Got most of the broad strokes of a sensor entity ready to probe the battery percentage over i2c and report that.

Needed, so I can not only monitor temperature in the RV for our doggo, but detect that RV lost power when the battery % drops, and alert us in case we're not home (internet/wifi runs off the inverter on the RV battery)

So far, so good.

Power works off lipo, i2c address responds when scanning. Will try out my #HomeAssistant code tonight.

New custom battery sensor for the DFRobot UPS Hat for my Pi Zero 2 W is working like a champ!

Need to add some alerts based on the battery, and then diagnose what's up w/ my BT integration to this EasyTouch RV thermostat... It's unreliable reconnecting, so I may need to try to keep a persistent connection open to it.
