Are there any KNX gateways that work with Apple HomeKit? I'm currently using the BAB Technologie EIBPORT V3 and have to speak to it via CUBEVISION 2 which works very poorly. I would love to find a way to simply control my KNX devices (primarily lighting) using HomeKit.
Although I don't have any personal experience with it, I found a Youtube video from ThinKNX which suggests that it would allow you to control KNX lights from Apple Homekit...
They outline here how to integrate ThinKNX with Apple Homekit.
Again, I'm afraid I'm not an expert, but I hope this could point you in the right direction!
