BLE Beacon suggestions?

I tested https://espresense.com/ on an esp32 i had laying around, and it seems to be working really well.
But i don’t wanna rely on my family remembering to start some app after a reboot so i would like some sort of ble beacons. There are a couple of threads regarding this matter but they are a few years old…
So, what are your suggestions regarding reliable and affordable hardware? Is Tile still the best option?

HA app.
It starts automatically for me after a reboot.

Ha! Never thought about checking it, great tip - Thanks!
