Frame and front panels for a three cavity appliance box

This is a cover for a EU three cavity wall box / appliance box. The frame is screwed in place. Any front panels can then be inserted. These are then fixed in place by inserting pins. All screws are then concealed. I use this to mount an outdated mobile phone and operate an esp32 with IR motion detector in the wall. esphome reports motion to Homeassistant and Homeassistant notifies the "Companion app" on the mobile to switch on the screen.
