The Allterco Robotics Shelly 1 Gen4 is a compact hardwired relay switch designed for smart lighting and electrical circuit control. It enables remote and timed on/off, local automation, and scripting for customized operation, while contributing to energy savings with low operating power consumption. The device supports a wide range of smart home systems and protocols, including Wi-Fi, Bluetooth 5.0, ZigBee, Matter, MQTT, and native KNX IP support, enabling seamless integration with Alexa, Google Assistant, Apple HomeKit, and Samsung SmartThings. Built-in safety features such as overload and overheating protection, as well as a 16 A rated relay, ensure reliable operation in a typical household environment, while the plastic housing and wall bracket mounting option allow for concealed installation behind switches or in junction boxes.

It is important to know

The most important thing when choosing is that the connection method fits the smart home you already have or are planning. Several of the protocols listed offer a choice, but they do not guarantee automatic compatibility with every platform.

• Before purchasing, check support for your chosen protocol in your ecosystem; the protocol label alone does not confirm compatibility with all devices or applications.
• If you plan on connecting via Matter, also check if your setup requires a Matter controller.
