Thanks. I miss-read it and thought it's energy harvesting from celular.

I already have some trackers on important stuff (like keys and school bag of kids if they loose it in the bus). But for other use cases it's either too large (cats) or makes no sense to have too many because then I'd have to replace a battery every few weeks ("everything else").

> replace a battery every few weeks

make it easy on yourself and change them all on the same day like a clock reset day like the recommendation for your smoke detectors. bite the bullet and change change some early to get them on the same schedule. it's worth it for sanity

I got a newish RF cat tracker lately and really like it: https://tabcat.com/

It's not app or Bluetooth based (has an included detector) and it works pretty well. Battery is supposed to last a few months. It easily fits on a cat collar and doesn't bother mine at all. I've been looking for something like this for years and someone finally made one!
