Product description: Shelly Shutter + BLU RC Button 4 - 2x roller blind controller + remote control for activating actions and scenes - WiFi / Bluetooth
The Shelly Shutter x2 + BLU RC Button 4 kit is designed to control two independent window coverings in a smart home system. Two Shelly Shutter modules allow for remote management of roller blinds, Venetian blinds, curtains, or awnings equipped with single-phase AC motors with limit switches. Each roller blind controller offers real-time energy consumption measurement , facilitating drive analysis and cost optimization. The kit includes the Shelly BLU RC Button 4 – a four-button Bluetooth Low Energy remote control that allows you to trigger scenes and actions without using your phone , providing convenient manual control of two roller blinds simultaneously. The devices operate via Wi-Fi , eliminating the need for additional control units.

Quick installation and advanced integration with the Shelly application
Shelly Shutter controllers are mounted in a standard junction box behind the roller shutter switch, allowing for modernization without any visible changes to the interior design. Each module works with single-phase AC motors equipped with mechanical or electronic limit switches, which must be properly set before connection. The devices operate locally via Wi-Fi or remotely via the cloud, and configuration is simplified via a built-in web interface. They work with the free Shelly Smart Control app, available for Android and iOS, which offers a clear interface for managing scenes and monitoring energy costs. The kit supports integration with Amazon Alexa, Google Smart Home, Samsung SmartThings, and MQTT- and KNXnet/IP-based automation systems.
Connecting to BLU RC Button 4 and controlling scenes
The Shelly BLU RC Button 4 communicates using Bluetooth Low Energy technology and allows you to control multiple devices with a single remote control . Four buttons support click combinations (single, double, triple, and long press), allowing you to configure up to 16 actions , such as opening, closing, stopping blinds, or triggering scenes. Each Shelly Shutter controller can act as a BLE gateway , receiving signals from the remote control and forwarding them to local or cloud-based automations. In practice, a single button can control two blinds simultaneously or assign separate actions to each blind.
