Does the Shelly Wave 2PM need a Z-Wave hub?

Yes. The Wave 2PM is a Z-Wave device and requires a compatible Z-Wave hub or controller (for example a Z-Wave gateway or Home Assistant with a Z-Wave stick) to join a network and be controlled from an app.

What load does each channel support?

Each of the two channels supports up to 10 A, with a combined total of 16 A and an 18 A peak, at 110-240 V AC or 24 V DC.

Does the Wave 2PM measure energy use?

Yes. Each channel separately measures voltage, current, power and consumed energy in kWh, plus totals, all visible in the app.

What Z-Wave frequency does it use?

The EU version uses Z-Wave at 868.4 MHz on the S800 chip (Z-Wave Plus V2) and also acts as a repeater in the mesh network.

Can I install the Wave 2PM myself?

Mounting involves working with mains voltage behind the switch, so we recommend installation by a qualified electrician. CasaSmart advises on hub choice and integration.

About this product

The Shelly Wave 2PM is a compact Z-Wave relay that fits inside the back box behind a switch and controls two independent circuits of up to 10 A each (16 A combined, 18 A peak). Every channel measures voltage, current, power and consumed energy, so you see the exact draw of each zone at a glance.<br><br>A dedicated cover mode lets the two outputs drive a single bi-directional motor for a roller shutter, awning or curtain, with position calibration. The module has two inputs for standard or momentary switches and runs on 110-240 V AC or 24 V DC.<br><br>Z-Wave communication at 868.4 MHz on the S800 chip adds extended range and a repeater role in the mesh. A compatible Z-Wave controller or hub is required for app control and automation scenes.

Smart scenarios

Three typical automations we set up after the install.

01Morning: warm light + blinds up + climate at 22 °C
02Leaving: lights off, arm sensors, close the gas
03Evening: warm ambient + cinema scene

Where it works

Use cases

In a Chisinau living room the chandelier and the LED strip are switched separately from the same double switch.

Independently controls two light circuits from a single back box.

Bedroom shutters lower automatically in the evening via a scene on the Z-Wave hub.

Uses both channels for a bi-directional roller motor with position calibration.

The owner sees in the app how much the water heater draws versus the outlet circuit.

Tracks voltage, current and energy on each channel.
