Short description

Shelly Duo Bulb E27 Gen3 (the Device) is a smart Wi-Fi/Bluetooth-operated dimmable LED white light bulb with color temperature control between 2700 K and 6500 K. It can be connected like any other bulb and operated with a switch, but it can also be controlled through Bluetooth connection with a Shelly BLU device (remote control or button). The Device can also be connected to a local Wi-Fi network, where it can work standalone or be controlled remotely via the Shelly Smart Control app. It can also be seamlessly integrated with popular platforms like Home Assistant, Google Home, Amazon Alexa, and SmartThings for voice control and automation.

Shelly Duo Bulb E27 Gen3 offers two advanced features: “Wi-Fi range extender” and “BLE Gateway”. When “Wi-Fi range extender” is enabled, the device retransmits the Wi-Fi signal to extend its reach, allowing other Shelly devices to connect to it. With the “BLE Gateway” functionality, it facilitates communication between BLE- and Wi-Fi-enabled devices. The Device can be accessed, controlled, and monitored remotely from any location with internet connectivity, as long as it is connected to a Wi-Fi router and the Internet.

Shelly Duo Bulb E27 Gen3 has an embedded Web Interface that can be used to monitor and control the Device and adjust its settings.
