Hi , I try to explain a bit more.
Everything is in the wall . I used one Raspberry 4 and an housing with a quit fan on top .
On top of the wooden wall is the PIR mounted. Works fine if someone is going from our kitchen to the living room. Both monitors come back in 5 seconds . If I am about 3 meters away the wake up process starts. Perfect for me and my family.
The controlling of the screens is a quite „push the Button“ Action . I started to control everything with Alexa , but early in the morning or quite late in the evening I don’t like to talk to much … but in general it also works .
Back to the buttons . I use a conbee Zigbee stick in a second Raspi placed in our basement of the house. On this second Raspi the software ioBroker is installed . So if I push the Zigbee button it will send an trigger to the ioBroker via conbee. The ioBroker translates with an program script the Zigbee trigger into an MQTT trigger . This MQTT is uses with the MQTT Bridge in the MagicMirror to push notifications to the MagicMirror … yes quite difficult, but it works fine and the delay is not to big ( Max 0.5 sec.)
I also started to test with real wired buttons. The plan was to bore holes in the wood an place a few buttons , but I decided to do in regards of a cleaner view of the wood wall.
Here some more pictures
