Shelly Wave 1PM

Quick verdict

The Wave 1PM is a single-channel Z-Wave relay with power metering that runs fully local through Z-Wave JS in Home Assistant. It is the single-circuit sibling to the Wave 2PM, with Z-Wave Long Range support for better reach to the controller. A solid behind-the-switch module if you are on Z-Wave and want energy data per circuit.

Standout: Single-channel Z-Wave relay with power metering and Z-Wave Long Range support, fully local via Z-Wave JS.
