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?

Home labs feel like that scene where someone uses 30 phones to call into a contest, wins, but cant figure out which one is ringing.

I don’t understand, is this for keeping track of the charge level of battery powered sensors?

Also, the description in the page is painful to read. I haven’t gotten into HA yet but I’m keeping an eye on stuff I find interesting, but I really hope having to trudge through saccharine LLM output to understand what each project does isn’t the standard.

It scans the network and dynamically adds or removes batteries which it then reports on percentage level, or if the battery status is unavailable. Pretty ingenious actually.

It's been around for years, so highly unlikely it's AI. I wouldn't call this a starting point for HA, but it did clean up my automations.

Yes, that seems to be the aim here. Also note that this is being provided by a community member and is in no way affiliated with the HA team

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.
