The Shelly 1 Mini Gen3 is the smallest WiFi smart relay in the world: it fits behind any switch, socket, or even inside a lamp's ceiling rose, and turns your installation into a smart home in less than 10 minutes. Its great advantage is the dry contact (potential-free), which allows it to control devices with a different power supply than its own—garage door motors, boilers, locks, or irrigation systems—without external modules. Thanks to the new Gen3 chip with 8 MB of memory, it gains stability and speed, and is ready for Matter upgrades, ensuring your automations run with imperceptible latency.
