From the project
Smart 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
RoomControl =========== Smart home room controller based on nRF52840 with MQTT and and IEEE 802.15.4 radio support. Buttons and relays for lights and blinds can also be connected with a local bus using LIN physical layer.
Control ------- 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.
