No, haven’t tried integrating via Pi
They did not really work that well IMO. Supposedly 1000+ users around me but they were rarely detected by other devices. For example it took 2 weeks before kiddos backpacks were detected at schools (both relatively large schools surrounded by housing). So not really useful for tracking location dependent on others phones having Tile app.
Curious how well they work in the Home Assistant integration.
In the intended use case of finding a lost item, might be fine for that. You might not find it immediately, but depending on the item, that might not be so important. Planning to use them on bags next time I travel.
