Did you guys consider distributing reference 3D printing designs to accommodate the Raspberry Pi at home. For example replacing a wall light switch? The wall niche for the Pi+ switch is a perfect place because it supplies electricity and is already reserved for a human interface.
I've developed a open hardware 3d printable LCD touchscreen which uses WiFi+MQTT to interact with Home Assistant which fits into a standard wall panel which you can find here: https://github.com/aderusha/HASwitchPlate
This still requires Home Assistant to be running somewhere else on the network and uses an ESP8266 instead of a Pi for several reasons, but it might help you out on your use case.
