Overview

What it is and who it is for

The Shelly Plus 1 UL is a UL certified, one-channel smart relay small enough to install behind a wall switch or in an electrical box. It switches one circuit through a potential-free (dry) contact and is controlled over Wi-Fi or Bluetooth from the Shelly app or a home automation system.

The relay carries up to 15 A at 240 VAC or 10 A at 30 VDC on resistive, capacitive and inductive loads (inductive with an RC snubber). It runs from 110 to 240 VAC, 24 to 48 VDC or a stabilized 12 VDC supply and draws less than 1.2 W. Wi-Fi range is up to 30 m indoors and 50 m outdoors, and Bluetooth reaches up to 10 m indoors and 30 m outdoors.

The module measures 37 x 42 x 16 mm, uses an ESP32 processor with 4 MB flash and operates from -20 to 40 °C. It accepts the Shelly Plus Add-on for sensor inputs.

  • Best for: retrofit control of lighting, garage doors, fans, irrigation valves and other single circuits behind a wall switch.
  • System fit: Shelly Plus series; Wi-Fi 802.11 b/g/n and Bluetooth 4.2; works with the Shelly Plus Add-on.
  • Important to know: the dry contact output is wired separately from the device supply; installation in an electrical box should be done by a qualified electrician.
