Low Battery Blueprint is awesome (lemmy.ca)

One automation for each battery was getting crazy. A temperature sensor in most rooms, motion detectors and a handful of door/window sensors. This blueprint creates an automation that manages all batteries dynamically. Really is amazing.

What blueprints do find useful?

I wrote some flows and functions in Node Red to send me a daily email with a list of all devices < 10% battery, but what I’m noticing is that several of my battery devices aren’t properly updating their status. I need to update it to also email me on unavailable battery devices too I guess.

Or just use this blueprint and it's all done for you.

I'm not quite sure how reliable these battery indicators are. I have a thirdreality moisture sensor at 0% for a week now. Still the original battery too, so you'd think that was actually properly calibrated. 😆

So I just go with the unavailable and deal with it then. Though the notification automation that I made for that did break at some point. I need to figure that one out again.

This automation also handles unavailable.
