Creasol DomBusTH is a small electronic board, 32x17mm, that can fit any blank cover with a 3mm hole in the centre, needed by the thermal/humidity sensor to exchange air with the room and to get the LEDs light out. It can be connected to the Domoticz controller by a RS485 serial bus (4 wires, 2 for 12/24V power supply, and 2 for data at 115200bps).

The electronic board is supplied with a 20cm long, 10 wires, assembly cable with plugin connector, so it's easy to connect the device to pushbuttons, switches, relays, ....

As other DomBus devices, DomBusTH minimizes power consumption, is automatically detected by Domoticz and each port is fully web configurable via Domoticz device description. See below how to change the factory-programmed address of each device, and how to configure each port as digital inputs, analog inputs, digital outputs, dimmer, buzzer, blind, .... by the Domoticz web panel.
