BTW, if it was me, I would just get the $45 remotec 8 button device and put that in the car. Each button can be tap, double tap, or long hold so you get 24 functions from the device. It’s battery-operated, zwave plus (which will give you a longer range then either zigbee or Homelink, at least on clear days), and there’s no soldering or wiring required, which could be important for those who have leased cars.
