The Shelly Wave 2PM smart relay module is a flush-mounted device with a meter capable of controlling two 230 VAC circuits. The Shelly Wave range uses the Z-Wave protocol for communication, so you will definitely need a Z-Wave Hub or USB coordinator to use the relay module. The module can be powered from both DC and AC voltages. It is also protected against overheating and overloading, ensuring safe operation even in small spaces with wall sockets.
