Create device_trackers for connected bluetooth devices

Describe the enhancement

A bluetooth device connected to a mobile phone running the companion app is likely within 10m of the coordinates of the phone. The companion app already tracks MAC addresses via sensor.*_bluetooth_connection's attributes connected_paired_devices and connected_not_paired_devices. This integration could also create device_tracker entities for the devices associated with those MAC addresses, using the coordinates of the mobile phone and a Bluetooth-based accuracy of 10m plus the GPS reading's accuracy.

Use cases

• Cheap and easy tracker for my car to which I've paired my phone, leaving my parking spot as the last known location when I shut it off.
• Tells me where I left my Bluetooth earbuds when I last walked away from them.

Anything else?

Prior to the deprecation of device_tracker.see, I used this automation and Python script to track connected devices:

automation:

alias: Update bluetooth devices' locations when detected by app
description: ''
mode: queued
max: 10
triggers:
  - entity_id:
      - device_tracker.phone1
      - device_tracker.phone2
      - device_tracker.phone3
      - device_tracker.tablet1
    trigger: state
conditions:
  - condition: template
    value_template: >-
      {%- set entity_id=trigger.entity_id.replace('device_tracker.', 'sensor.')
      ~ '_bluetooth_connection' %}

      {{ states(entity_id) != 'unknown' and states(entity_id) | int > 0 }}
actions:
  - data:
      device_tracker: '{{ trigger.entity_id }}'
      bluetooth_connection: >-
        {{ trigger.entity_id.replace('device_tracker.', 'sensor.') ~
        '_bluetooth_connection' }}
    action: python_script.report_bluetooth_device_locations

report_bluetooth_device_locations.py:

device_tracker = data.get('device_tracker')
bluetooth_connection = data.get('bluetooth_connection')

logger.debug("device_tracker: {}".format(device_tracker))
logger.debug("bluetooth_connection: {}".format(bluetooth_connection))

dt = hass.states.get(device_tracker)
bt = hass.states.get(bluetooth_connection)

macs = []
cpd = str(bt.attributes['connected_paired_devices'])
for mac in cpd.lstrip('[').rstrip(']').split(','):
    mac = mac.strip()
    mac = mac.lstrip('\'').rstrip('\'')
    if mac != '':
        macs.append(mac.lower())

cnpd = str(bt.attributes['connected_not_paired_devices'])
for mac in cnpd.lstrip('[').rstrip(']').split(','):
    mac = mac.strip()
    mac = mac.lstrip('\'').rstrip('\'')
    if mac != '':
        macs.append(mac.lower())

for mac in macs:
    logger.info('Reporting location for {} based on {}'.format(mac, dt.entity_id))
    words = mac.split(' ')
    if len(words) > 1:
        # Gotta separate the mac addr and host name
        mac = words.pop(0)
        hostname = ' '.join(words).lstrip('(').rstrip(')').lstrip('"').rstrip('"')
        mac = mac.lstrip('"').rstrip('"')
    else:
        hostname = '_'.join(['BT', mac])

    dev_id = '_'.join(mac.split(':'))

    # Devices to skip reporting
    if hostname.lower() in ['nrf5x']:
        logger.debug('Skipping nRF5x device {}'.format(mac))
        continue

    hass.services.call('device_tracker', 'see', {
        'dev_id': dev_id,
        'host_name': hostname,
        'mac': '_'.join(['BT', mac]),
        'location_name': dt.state,
        'gps_accuracy': dt.attributes['gps_accuracy'] + 10,
        'gps': [
            dt.attributes['latitude'],
            dt.attributes['longitude'],
            ],
        })
