Virtuel PHEV Tracker

alias: Virtuel PHEV Tracker
description: >-
  Kombinerer bilens egen GPS med telefoners GPS (ved kørsel) for at sikre
  hurtigere opdateringer. Bruger Bluetooth/WiFi til at detektere føreren og en
  Bayesian-sensor til at bekræfte 'Hjemme'-status for at undgå GPS-drift.

# ------------------------------------------------------------------------------
# VIRTUAL PHEV TRACKER - ADVANCED VERSION
# ------------------------------------------------------------------------------
# This automation creates a virtual device_tracker that intelligently switches
# between multiple GPS sources (Car native GPS vs. Driver phones).
#
# PREREQUISITES:
# 1. A Bayesian binary_sensor (e.g., binary_sensor.yeti_presence) for home detection.
# 2. A native car integration (e.g., device_tracker.yeti_location).
# 3. Bluetooth MAC addresses for the car's dongles/headunit.
# ------------------------------------------------------------------------------

triggers:
  # 1. Trigger when "Car is Home" confidence changes (Bayesian)
  - trigger: state
    entity_id: binary_sensor.yeti_presence
    to: null
    id: bayesian
  # 2. Trigger when Primary Driver's phone moves
  - trigger: state
    entity_id: device_tracker.jacob_nothing
    attribute: latitude
    id: jacob
  # 3. Trigger when Native Car GPS updates
  - trigger: state
    entity_id: device_tracker.yeti_location
    attribute: latitude
    id: car
