Product information

Description

The Shelly 1 Gen4 Zigbee/Matter controller is a compact backplane controller with potential-free contacts that enables remote control and automation of electrical circuits and devices via local network or the Internet. It supports multiple communication protocols (Wi‑Fi, Bluetooth, Zigbee, Matter) and can be integrated with platforms such as Google Home, Alexa and SmartThings. The device also functions as a Zigbee repeater and can improve connection stability where signal is weak.

Advantages

The Shelly 1 Gen4 supports four wireless protocols (Zigbee 802.15.4, Wi‑Fi 802.11 b/g/n, Bluetooth 4.2 and Matter), has low power consumption (< 1 W) and does not require a neutral wire for installation. Built‑in scheduling (up to 20 schedules), ShellyScript support, MQTT and HTTP APIs allow flexible automation and integration with third‑party systems. Small dimensions (37 × 42 × 16 mm) and light weight (26 g) make it suitable for mounting behind switches or inside distribution boxes.

Suitable for

  • Remote switching and automation of lighting circuits
  • Control of small appliances, motors and relays in residential and commercial premises
  • Integration into Zigbee or Matter smart‑home ecosystems and voice assistants
  • Extending Zigbee network range by acting as a repeater

How to use

Install the Shelly 1 Gen4 on a wall console or inside an electrical box following recommended wiring practices: strip conductors 6–7 mm and tighten screw terminals with a maximum torque of 0.4 Nm. Connect the device to the chosen ecosystem via local Wi‑Fi, Zigbee coordinator, Bluetooth or Matter controller. Configure device parameters, schedules and automation through the built‑in web interface, ShellyCloud app or via HTTP API and MQTT. Use the potential‑free contact to switch loads within the specified voltage and current limits and add Zigbee repeaters where needed to improve mesh coverage.

Usage recommendations

Use an overcurrent circuit breaker (EN60898‑1, characteristic B or C, rated current max. 16 A, minimum breaking capacity 6 kA) for external protection. Ensure installation in environments within the specified temperature and humidity ranges and follow local electrical codes. When integrating into a Zigbee mesh, position the controller to maintain reliable signal paths and avoid prolonged exposure to temperatures outside the operating range.
