Interior lighting automation
LED strip lights seem ideal for vans. The controllers are 12-volt DC-powered and can run a long strip of lights. The eight zone wall-mounted remote can control up to eight strips, and the wifi bridge allows control via app.
But, how to control it all via HomeKit?
This Reddit post is a start, which leads to the HomeBridge project and the MiLight integration. This ArsTechnica post walks through HomeBridge setup for a slightly different use.
Ideally, iOS Home automation can be used to turn the lights on and off coordinated with events in other devices.
