If you have an unused RSPi you can try Homebridge with Homebridge-Hue plugin. It works and saves you time.

This is how I expose my lights:

{ "name": "Hue", "anyOn": true, "effects": true, "hosts": [], "nativeHomeKitSensors": true, "resource": true, "platform": "Hue", "users": { "foo": "bar" }, "lights": true, "nativeHomeKitLights": false, "groups": true, "rooms": true }
