I'm just thinking to use hubitat in all family cars
As a startup
- install under the hood or inside the glove box something like OUKITEL C11 Pro 5.5" MTK6739 Quad Core Android 8.1 4G LTE Smartphone 18:9 Face ID 3GB RAM 16GB ROM 8MP+2MP/2MP Mobile Phone-in Cellphones from Cellphones & Telecommunications on Aliexpress.com | Alibaba Group or Topsion Android 9.0 Smart TV BOX 4G DDR3 32G EMMC ROM Set Top Box 6K 3D H.265 Wifi media player TV Receiver-in Set-top Boxes from Consumer Electronics on Aliexpress.com | Alibaba Group ( less reliable in terms of powering device ) to get hubitat APP with presence functionality there
-
https://play.google.com/store/apps/details?id=com.termux&hl=en to have access to device remotely via SSH and all other linux stuff
-
install node-red inside Running on Android : Node-RED to get any imaginable automation via Bluetooth and wifi connectivity
-
Alexa app
-
hubitat hub itself
What I see as a great functionality are
- car security when it is far from the mobile of the owner and starts moving. Same on opening doors, hood, boot door
- connection to car computer to monitor everything
- when the car is going close to the house - rule machine can start events inside. "Alexa, make me a coffee, please"
