Shelly 2PM Gen4 represents a major leap in smart home automation with a new multi-protocol chipset that natively supports Wi-Fi 6, Zigbee 3.0, Bluetooth 5.0, and Matter. Its dual-channel design is perfect for controlling two separate lighting circuits or for automating shutters, blinds, curtains, and awnings via a bidirectional AC motor.
Key Features
True Multi-Protocol Connectivity: Straight out of the box, Gen4 supports Wi-Fi 6, Zigbee 3.0, Bluetooth LE, and Matter. It can even act as a Wi-Fi range extender and Zigbee router, actively strengthening your smart home's local mesh network.
Advanced Shutter and Blind Control: In "Cover Mode," it can manage motorized blinds and curtains. It supports precise calibration based on power consumption, allowing you to open blinds exactly to 50%, or even control the slat tilt angle based on the sun's position.
Dual Power Monitoring: It boasts independent real-time power measurement for both channels. You can accurately monitor how much electricity two separate appliances or lighting circuits consume and trigger automations if power thresholds are exceeded.
Next-Generation Processing Power: Powered by the new ESP-Shelly-C68F microcontroller with 8 MB of flash memory. This allows the relay to execute complex local scripts (mJS), HTTP webhooks, and advanced scheduling directly on the device, ensuring your automations execute instantly even without internet access.
Comprehensive Safety Protections: Designed in accordance with strict safety standards, it includes internal temperature sensors for overheating protection, as well as mechanisms for shutdown in case of overvoltage, overcurrent, and overpower. In cover mode, it also supports obstacle detection.
