python-ble-detector is an example Docker / Python Project to detect BLE (Bluetooth Low Energy) beacons using a Raspberry Pi Zero W

I personally use this python script to manage smart powersockets via bluetooth button detection and assistant relay.

Have docker installed on your Raspberry Pi Zero W

make python-ble-detector 

Add you own bluetooth device to the BLE_STATES array

DESK = {'mac': 'AB:CD:EF:GH:IJ:KL', 'name': 'Desk', 'state': 0, 'lastUpdated': datetime.now()}
BLE_STATES = [DESK]

and then overwrite any custom functions you want to call in the ble scanner function

def handleDiscovery(self, dev, isNewDev, isNewData):
        if isNewDev:
            for button in BLE_STATES:
                if button.get('mac') == dev.addr:
                    print("DETECTED: button: %s, Name: %s" % (button.get('mac'), button.get('name')))
                    toggle(button)

Do whatever you want
