About Shelly — Europe's Smart Home Innovator
Shelly is a European smart home brand that has rapidly become one of the most trusted names in home automation. Founded by Allterco Robotics, Shelly specializes in WiFi-controlled smart relays, smart plugs, sensors, and automation controllers that operate without requiring a proprietary hub. Unlike many competing systems that lock you into a single ecosystem, Shelly devices connect directly to your existing WiFi router, making them incredibly simple to set up and integrate into any home.
What truly sets Shelly apart is their commitment to energy monitoring. Nearly every Shelly relay and plug includes real-time power metering, allowing you to track electricity consumption down to the watt. This feature alone can help homeowners identify energy-hungry appliances and reduce monthly bills. Shelly devices are also fully compatible with all major smart home platforms including Amazon Alexa, Google Home, Apple HomeKit (via firmware), and the open-source powerhouse Home Assistant — with native MQTT support for advanced users.
Designed with DIY enthusiasts and professional installers in mind, Shelly products are compact enough to fit behind existing wall switches and inside electrical boxes. The brand offers a complete ecosystem: from tiny single-channel relays like the Shelly Plus 1 to professional-grade DIN-mountable controllers like the Shelly Pro 4PM. With regular firmware updates, an active community, and a 2-year warranty, Shelly has earned its reputation as the go-to choice for reliable, no-hub smart home automation.
