I have built a flow with which it is possible to connect the Philips Hue motion detector to Apple HomeKit. This provides the possibility to receive a notification as soon as the motion detector is triggered. The addon is that you can Switch the Notification ON and OFF with a Amazon Dash Button.

You need to install the following Nodes:

node-red-contrib-homekit node-red-contrib-huemagic node-red-contrib-amazondash

So you can use it with a AppleTV 4 to notificate you in WAN.
