Code review - 12v battery deep_sleep loop and MQTT combined

Have a dig into this config, you’ll probably pick up a few relevant and useful tidbits.

I use ChatGpt in targeted ways for ESPHome (generate repetative config, helping with some lambdas, adding small parts of logic then careful testing), but don’t expect decent results like you might with other languages/uses, and don’t expect a positive response from the community here when you mention you want to debug AI generated trash.
