Smart relays & switches

A Shelly smart relay (often called a smart switch) installs behind your existing wall switch and makes your lighting, water heater, oven or outlets smart, with no new switches and no work on the walls. You get phone control, schedules and, on most models, power metering.

How to choose a smart relay

Shelly 1 and Shelly 1PM handle a single point (lighting, water heater, outlet), with the PM adding power metering. Shelly 2PM controls two lighting circuits or one electric roller shutter. Shelly 1 Mini and 1PM Mini are the smallest models for tight spaces, and in the electrical panel you have the Pro models on a DIN rail. Shutter controllers have a category of their own: smart shutter controllers.

Smart relays for lighting

For regular lighting, Shelly 1PM and 1PM Mini are the right fit: they go into the wall box behind the switch, the wall switch keeps working as usual, and you add phone control, timers and power metering. Shelly 2PM controls two lighting circuits from the same box, and Shelly Dimmer Gen4 adds dimming for dimmable LED bulbs, up to 200 W. For 12/24 V LED strips there is Shelly Plus RGBW PM. Wiring guides: Shelly 1PM Mini and Shelly 1 Mini.

Smart relays without a neutral wire

Many older apartments have no neutral wire in the switch box, and most smart relays need one. Shelly 1L and 2L Gen3 are designed exactly for this: 1L for one lighting circuit and 2L for two, up to 200 W (and up to 700 W on the second output of the 2L). With low-wattage LED bulbs you add a Bypass, which prevents flicker. Dimmer Gen4 also works without a neutral wire, with a Bypass. Guide: connecting Shelly 1L to lighting.

Wireless light switches

Need a switch where there are no wires, say at the top of the stairs or next to the bed? A Shelly wireless button sticks to the wall and controls the lighting through the smart relay, without opening the wall.

What a smart relay can do

Control from anywhere in the Shelly app, schedules by time or by sunrise and sunset, automations with sensors and buttons, voice control through Google Home and Alexa, while the wall switch keeps working just as it always has. The devices run on your home Wi-Fi network and keep following their schedules even when the internet is down. They also integrate with Home Assistant and MQTT.

How much does a smart relay cost?

For a single point: Shelly 1 Mini Gen4: ₪79, Shelly 1PM Mini Gen4 for lighting: ₪89, and Shelly 1PM Gen4 for a water heater, oven or outlet: ₪115.

Installation

The smart relay connects to the wires behind your existing switch, so we recommend having it installed by an electrician. You can book an electrician who knows Shelly products and read the complete smart home installation guide. Not sure which model is right for each point?
