This is one of my more ridiculous automations.
The previous owners of the house had LED strips under the cupboards in the kitchen.
I replaced the drivers with Zigbee ones, but I never really worked out a use-case.
Turns out my coffee grinder uses bluetooth for firmware upgrades (because of course it does)
When ever the grinder is on, it sends Bluetooth LE advertisments. (You can see where this is going).
So, I threw #esphome on to a spare ESP32, and added the ble_presense binary sensor.
Now every time I turn on the grinder, home assistant turns on the light above the coffee machine. (and it turns off when the grinder goes back to sleep)
I wrote up some more details here: https://myles.eftos.id.au/blog/2025/01/29/so-my-coffee-grinder-has-bluetooth/
