I bought 5 of these to use with my Raspberry Pi 4B project BeaconAir. BeaconAir monitors the Raspberry Pi in the house using trileration and triangulation of iBeacons and controls the lights in the house to turn on and off nearby lights. The project was great and I've added it to the book I'm writing.
