Shelly Multicolor Bulb E27 Gen3
The Shelly Multicolor Bulb E27 Gen3 is a smart, color LED bulb built on Shelly’s powerful Gen3 architecture. It offers the same brilliant, tunable white light (2700K to 6500K) as the Duo model, but adds a massive palette of 16 million RGB colors. Equipped with a custom ESP32-C3 chip and 8 MB of flash memory, it acts as an intelligent node in your smart home, not just a simple light source.
In addition to smooth, flicker-free dimming and vibrant ambient lighting, it functions seamlessly as both a Wi-Fi range extender and a Bluetooth (BLE) gateway, extending your local smart home network while eliminating the need for dedicated proprietary hubs.
Key Features
-
16 Million Colors and Tunable White Light: Instantly change the atmosphere in a room from focused, crisp white (6500K) for work to deep, saturated RGB colors for gaming or movie nights. The transition between colors is incredibly smooth and flicker-free.
-
Dual Mesh Node: Powered by the Gen3 processor, it serves as an active network infrastructure device. It can repeat your Wi-Fi signal to eliminate dead zones and act as a BLE gateway, allowing local Bluetooth sensors to communicate with your main network.
-
Built-in Power Consumption Monitoring: Features real-time energy metering, allowing you to track exactly how much electricity your lighting consumes and optimize smart schedules to save on your energy bill.
-
Night Mode and Custom Transitions: Set specific parameters for nighttime routines. The bulb can be configured to automatically dim to a soft, low-brightness warm white (or a specific RGB color) at night, preventing harsh glare if you wake up for a glass of water.
-
Advanced Local Automation: Its 8 MB of flash memory enables the execution of complex local scripts (mJS), HTTP webhooks, and up to 20 independent schedules directly on the device – meaning your lighting rules execute instantly, even if your internet connection goes down.
-
Universal Compatibility: Operates 100% locally with support for MQTT, UDP, and REST API. Out of the box, it integrates seamlessly with Home Assistant, Apple HomeKit, Google Home, Amazon Alexa, and Samsung SmartThings platforms.
