Jochen0x90h/RoomControl3Smart home room controller based on nRF52840 with MQTT and and IEEE 802.15.4 radio support. Buttons and relays for lights and roller shutters can also be connected with a local bus using LIN physical layer
Switch is an open-source printed circuit board by Jochen0x90h, from the Jochen0x90h/RoomControl repository on GitHub. It is a 2-layer board of 70.5 × 70.5 mm with 29 parts on 39 nets, routed with 460 tracks and 32 vias.
It is built around the NCV7428MW3 and D2F-01. Its parts include 8 switches, 5 resistors, 5 diodes, 4 capacitors and 4 connectors. It belongs with the home automation and IoT and radio and wireless boards and the STM32 boards of this library.

This is a 3D printed box with a display and digital potentiometer that gets installed in each room instead of the floor heating thermostat. It can control the heating valve using an opto-triac, connect to light and blind switches and relays using LIN physical layer and to battery-free switches (EnOcan) using an IEEE 802.15.4 radio interface.
This is a wall switch and actor for lights and blinds that can be mounted behind Eltako E-Design frames and rockers. It connects to the Control via a bus based on LIN physical layer.
This is a hat for rpi or compatible single board computers that connects to multiple Controls via a IEEE 802.15.4 radio network and to an MQTT broker such as mosquitto.

It measures 70.5 × 70.5 mm and has 2 copper layers, 1.6 mm thick.
29 parts, built around the NCV7428MW3 and D2F-01. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Jochen0x90h/RoomControl repository on GitHub, at the commit this page was made from: the board is pcb/switch/switch.kicad_pcb and its schematic pcb/control/control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Jochen0x90h before reusing the design.
