The Shelly BLU Button Tough 1 ZB is a durable, water- and dust-resistant multi-protocol smart button offering both Bluetooth (Shelly BLU) and Zigbee 3.0 connectivity. Featuring a single large, tactile button, it allows quick scene triggering and reliable control of lights, blinds, garage doors, alarms, and more – perfect for situations where using a phone or voice assistant is inconvenient.
Designed for everyday and outdoor use, the “Tough” enclosure resists impacts, dust, and splashing water, making it ideal for terraces, garages, workshops, warehouses, or any area with frequent physical contact. The button supports multiple press patterns (single, double, triple, long press), allowing different actions to be assigned to each – for example: single press to toggle lights, double press for a favorite light scene, long press to arm/disarm an alarm.
Its dual-radio design enables flexible integration: in Shelly BLU mode, local, cloud-independent scenes can be triggered via Shelly gateways or Shelly Plus/Pro/Gen3/Gen4 devices; in Zigbee mode, it pairs with popular hubs like Home Assistant (ZHA/Zigbee2MQTT), SmartThings, and others. This makes it ideal for hybrid Shelly and Zigbee environments.
The compact form factor offers flexible mounting options: it can be carried on a keychain for quick access or fixed to a wall or furniture for consistent scene control. The low-power design ensures long battery life (usage-dependent), while encrypted wireless communication ensures safe operation in both home and business settings.
