This device is for use with standard switches and is designed to be mounted in a socket. With it, any 1-3 key switch turns into a "smart" Zigbee switch.

The Chinese offer a lot of solutions for Zigbee switches, but they all have certain flaws. These are either touchscreens with a glass panel without tactile communication, or keyboards with a controversial design and minimal key travel. In this regard, the idea of ​​​​this simple device was born, which allows you not to abandon the usual switches.

The device based on the E18-MS1-PCB module has 3 control channels, on one of them a relay can be used if necessary. It is powered by two AAA elements, supports binding.

PTVO firmware (configurator, possible customization).
