Short description
Shelly 1-Channel Decoupler 230V / Shelly 4-Channel Decoupler 230V is an electronic component that interconnects two separate electrical circuits (AC to DC) by means of a light sensitive optical interface (an octocoupler). It is designed for use with Shelly Plus Uni, Plus Add-on, Plus RGBW PM and Pro RGBW PM devices and different controllers, such as switches and buttons. It allows for switching DC inputs using AC supply.
Main features
Isolate and control DC loads: Use existing AC for triggering inputs on DC devices. Suitable for retrofits, external/specialized switches.
Use cases
Third-party sensor connectivity: Connect third-party sensors that require/work on/with AC to DC Inputs, for example - PIR, Microwave, Light control, Infrared motion, Hand wave sensors.

What are the differences between the different generations of Shelly products?
Each new generation adds more power, memory, and features:
Gen 1 offers basic control;
Gen 2 (Plus Series, Mini Series, Pro Series) adds Bluetooth, scripting, and better security;
Gen 3 improves performance, adds Matter (starting from firmware version 1.6.0 or newer) and advanced monitoring;
Gen 4 offers multi-protocol connectivity, featuring Wi-Fi 6, Bluetooth, Zigbee, and Matter.
Can I control the device via Bluetooth?
No, the protocol is used only for device inclusion, allowing for quick and easy setup through the Shelly Smart Control app.
For bluetooth control it is required to have another Bluetooth device such as Shelly BLU Button or Shelly BLU Motion to interact.
Additionally, Shelly devices can function as a BLE gateway, bridging Shelly BLU devices to your Wi-Fi network.
Is it possible to use the device without a hub?
Yes, Shelly devices (except for Wave devices) operate independently without the need for a hub. They connect directly to your Wi-Fi network, and you can control them via the Shelly Smart Control app, web interface, or through integrations with platforms like Google Home, Alexa, Home Assistant and Samsung SmartThings.
