The Shelly i4 GEN3 WiFi + Bluetooth module does not have a relay, but can wirelessly control other Shelly relays by sensing the position of up to 4 switches. It can also be used to control scenes from a wall switch and to set up wireless switching. Can also be used as a phase monitoring module connected behind a small circuit breaker.

Product Details

Shelly i4 GEN3 is a special smart home product launched in 2024 and is the successor to the Shelly Plus i4. It is designed for installation behind conventional wall switches. The device does not have a relay but can manage the state of up to 4 switches or other input/control devices. Based on their state, it can wirelessly control other Shelly relays, sensors, or devices via HTTP/HTTPS, MQTT, or CoAP protocols.

The primary function of Shelly i4 GEN3 is to wirelessly "connect" a switch to devices connected to Shelly relays installed elsewhere in your home (or even in other locations). Mounted behind the switch(es), Shelly i4 GEN3 can detect changes in the state of the switches and send commands via WiFi to Shelly PLUS, PRO, or GEN3 relays, controlling multiple devices in a group with one switch. It can also pair with a Shelly smart relay when the switch and the light are physically separated or lack direct wiring between them.

The device can handle up to 4 physical signals from switches (two-position or toggle switches), with up to 4 events assigned to each, enabling a total of 16 commands. You can assign different commands to switching modes in the Scene function, or use DDD control between devices to send commands to other devices via URL. Shelly i4 GEN3 is also suitable for controlling scenes from a physical wall switch.

As with other Shelly devices, it does not require a hub or gateway to operate, connecting directly to your WiFi router.

For example, a single wall switch can be programmed to turn devices on/off with a single press, control lights or shades with a double press, or manage multiple devices simultaneously with a triple press. You can also use the Scenes function in the Shelly Cloud app to create sequential or delayed actions.

Shelly i4 GEN3 can also be used to monitor whether a switch is on or off, or to track the current flow in a specific circuit, setting rules in the Shelly Cloud app to turn other Shelly WiFi relays on/off via wireless control.

Device Housing:

Shelly i4 GEN3 has the same dimensions as its predecessor, making it compatible with standard DIN adapters for GEN3 relays. Wiring diagrams are included for straightforward setup.

Bluetooth Pairing:

Pairing is performed via the new Shelly Cloud app and is not compatible with the previous version of the app. The built-in Bluetooth chip ensures fast pairing.

More Powerful Processor, More Features:

The ESP32 processor from Shelly Plus i4 has been replaced in GEN3 products with the ESP-Shelly-C38F processor, offering faster processing, more power, and double the memory (8 MB), ensuring enhanced features and faster performance compared to the PLUS product line.

Shelly i4 GEN3 requires a constant power supply of 110–240 V AC.

Product Features:

  • Direct connection to a WiFi router, no hub or gateway required.
  • Compatible with 110–240 V AC supply voltage; supply voltage and switch/circuit voltage must be the same.
  • Manage up to 4 switches and up to 4 states for each, using the Scene function in the Shelly Cloud app to control multiple devices.
  • Compatible with the Shelly Cloud app for Android and iOS, Amazon Alexa, Google Assistant, and home automation systems via MQTT, CoAP, and REST API.
  • Factory firmware can be easily replaced if needed.
  • Supports mjS scripts, allowing the creation of custom functions and features.
  • GEN3 supports virtual components for additional functionalities and value changes via HTTP commands.
  • Bluetooth gateway functionality allows communication between GEN3 and Shelly BLU sensors or remote controllers.

  • Cloud Mode: Connects to the free Shelly Cloud, manageable via the Shelly Cloud app and website.
  • LAN Mode: Devices can only be controlled by other devices on the same local network.
  • WiFi Access Point Mode: If there is no permanent WiFi network at the installation site, the device can broadcast its own WiFi network for direct control via a mobile phone or notebook.

Additional Technical Specifications:

  • Power supply: 110–240 V AC (±10%).
  • Requires both phase and neutral wires to operate.
  • Width: 17mm
