I only have an apple iphone 4 which I tried unsuccessfully to connect to the switch. I have the incipio command kit app on that if there is a way to extract it for backup??
I do not know about apple products, Homekit is built into the apple OS? The way I use the incipio switch is with HomeAssistant running on a raspberry pi4. The HA software handles the triggers with the HomeKit addon, it can see the switch. In the daytime it turns off the motion sensor after 10 seconds, and at night I leave it on longer since it is connected to outdoor LED trees. The motion sensor I also use to trigger my kitchen lights when it senses me walking in that area.
If you read this more than once, sorry for that.
