I came across an interesting BLE beacon recently.
It is configurable to send your basic beacon info (iBeacon, Eddystone TLM, Eddystone URL, and/or Eddystone UID format), but the cool thing is that it can send an additional beacon ID when it is moved. I’m using it to track whether my trash can is at the curb on trash day AND whether the can has been moved once it’s at the street. You could also tell the difference between a moving vehicle or a stationary one. I’m also thinking of using one to sense when my mailbox has been opened.
Lots of possibilities.
The vendor, BlueCharm, is reponsive and friendly, too.
Note: I’m using Room Assistant to report BLE data to Home Assistant.
