Smart plug Shelly Wave Plug S with energy monitoring, Z-Wave, control via Z-Wave hub, compatible with Home Assistant

The Shelly Wave Plug S is a Z-Wave smart plug with power monitoring and overheating protection, designed for remote control of any connected household appliance from your phone, tablet or home automation system. The built-in LED visually indicates the consumption level: green for 0W, yellow for moderate consumption and red when the load exceeds 85% of maximum capacity.

The plug includes overload protection: if the maximum current of 16A is exceeded by more than 10% for more than 5 seconds, the device automatically switches off its output and sends an overcurrent notification to the Z-Wave hub, protecting both the plug and the connected appliance.

Being compatible with the Z-Wave Plus protocol and featuring a signal repeater function, the plug automatically extends Z-Wave network coverage in the home, also helping to increase the range of other Z-Wave devices installed far from the hub.

Note: this plug requires a Z-Wave hub or controller for full operation; it supports SmartStart and Security 2 (S2) for fast, secure inclusion in the network.

Practical use cases

• Connected to a floor or desk lamp, it lets you switch it on and off remotely or on a schedule, with no changes to the electrical installation.
• Used for a charger, a travel kettle or other appliances that should not be left plugged in permanently, with scheduled automatic switch-off.
• Useful for simulating presence in the home during holidays, switching electrical appliances on and off on a random schedule.
• Monitors the consumption of the connected appliance, giving a clear estimate of the monthly running cost.
