'Beacon' to trigger unlock of a gate

1

What would be the best beacon type/technology to unlock a gate when a bicycle is detected nearby?

Doesn’t need to be super reliable (it’s not the front door and if it opens in error it’s not the end of the world, I’d also design some intelligence into the automation).

But needs to be a beacon type that would only be detected if it’s very near, like within say 2metres, but also I don’t want it to be like that you have to tap something on something else.

Is that possible?!?! :smiley:

Look up Bluetooth BLE beacons, Bluetooth proxies and an integration in HACS called Bermuda
