Hi, I'm hoping there might be a Zigbee device that works like an airtag (within your ZigBee network at least). Maybe you can trigger it making a noise, or you could see which router it was connected to, or had the strongest connection to.
Use case would be attaching it to phones/keys to get an idea of where they are (rather than presence sensors for humans)
I don't think ZigBee works this way (e.g. happily supports moving around the network in a big way, like from one end of home to other). But figured that I'd ask in case I am wrong about it.
For what its worth Im Europe based.
