The device is designed to connect up to 3 sensors with outputs "dry contact", such as switches, leakage sensors, reed switches, etc.
The device allows you to transform a regular wall switch with a number of keys from 1 to 3 into a smart switch that operates using the Zigbee protocol. The compact size of the device allows it to be placed in a mounting box together with the switch.
