Smart button Shelly BLU Button Tough 1

The Shelly BLU Button Tough 1 is a compact, Bluetooth-operated smart button designed for reliable control of lighting, appliances and pre-set scenes without requiring a mobile phone. Built from durable plastic and powered by a 3V CR2032 battery (up to 2 years of typical use), the device measures 42 × 42 × 13 mm and is supplied as a single unit in a box. Its rugged construction provides resistance to shock, water splashes and dust, allowing use both indoors and outdoors with fast response times and broad range.

Advantages

The button supports multi-click combinations to trigger up to four pre-set actions or scenes and can be integrated with Shelly scripting to run complex local automations based on RSSI and location. Communications use Advanced Encryption Standard (AES) to protect data. The compact, portable design is available in multiple colours and is engineered for high resilience in demanding environments.
