@kjoglums : I’m eager to have a PR toward this binding. It’s important to enhance it with the fruits of your work.
Please, note that for each car, VOC service identifies available features, these are captured when discovering the car :
Also see that the honk/blink command is insufficient as is for the OpenHab binding, as location (long,lat) apparently is required included, although, I can not foresee this being a relevant command for me.
IIRW the binding sends honk/blink along with car location (lat,long), so it should work fine.
