The Shelly Button 1 allows you to trigger predefined scenes and devices in the Shelly app at the push of a button. Thanks to the built-in, USB-rechargeable battery, you can use the button as a remote control. It can also be operated with a constant power supply via USB, reducing the response time to 100 ms. The Shelly Button is waterproof and certified to IPX5. It should not be submerged in water, but moisture and rain won't harm it. No matter the weather conditions, the Shelly Button 1 is ready for you. With the Shelly Button 1, you can control up to 4 different lights or scenes. Simply set the appropriate action in the app for each pressing sequence. A single click turns the light on or off, double-clicking dims your light, and triple-clicking sets the brightness to 25%. Everything is in your hands.
