About Relays & Switches

A smart relay is a small module that lets you control a circuit from an app, a voice assistant or an automation. Some models fit behind an existing wall switch, and others mount on a DIN rail in a switchboard. The relays here are made by Shelly, and the right model depends on what you want to control and how the circuit is wired.

Lights and appliances

For a standard circuit, the Shelly 1 Gen3 switches loads up to 16 A. If space behind the switch is tight, the Shelly 1 Mini Gen4 is rated at 10 A and the Shelly 1 Mini Gen3 at 8 A.

Power monitoring

A PM model also shows how much power a circuit uses. The Shelly 1PM Gen4 and Shelly 1PM Gen3 add live monitoring, and the Shelly 1PM Mini Gen3 is a compact option for lights and small appliances up to 8 A.

No neutral at the switch

Many older light switches have no neutral wire. The Shelly 1L Gen3 and two-channel Shelly 2L Gen3 are designed for this wiring, and a Shelly Bypass is available if your installation needs one.

Blinds, shutters and curtains

The Shelly 2PM Gen4 is a two-channel relay with power metering for shutters, blinds and curtains. For switchboards, the Shelly Pro Dual Cover PM controls two covers, and the Shelly Qubino Wave Pro Shutter suits Z-Wave systems.

Switchboards and control circuits

DIN rail relays mount in a switchboard and add LAN as well as Wi-Fi and Bluetooth. The Shelly Pro 1PM, Pro 2PM and Pro 4PM include power metering. For contactors and other control circuits, look at dry-contact models such as the Shelly 1 Gen4, Pro 1 and Pro 3. The Shelly Plus Uni is a low-voltage sensor and relay module.

Installation

Relays that connect to mains wiring must be installed by a licensed electrician in Australia. We are a retail store and do not install directly, but we can recommend qualified installers and help you check compatibility before you buy. If you want to control brightness, see our smart dimmers.
