Shelly BLU Button1

Quick verdict

A small, cheap Bluetooth button that gives you up to four distinct actions (single, double, triple, long press) for triggering Home Assistant automations. Stick it on a nightstand, a wall, or carry it in a pocket. You need a Bluetooth adapter on the Home Assistant host or a Bluetooth proxy (a Shelly Gen2+ device, the Shelly BLU Gateway or an ESPHome node) within range, but once that is in place, these buttons are the cheapest way to add physical scene triggers everywhere.

Standout: Pocket-sized Bluetooth button with multi-press detection - up to four distinct actions from one button.

Compatibility snapshot

Why it stands out

• tiny, portable button that supports single, double, triple press, and long press actions
• battery powered and adhesive-backed - stick it anywhere without wiring
• very cheap, making it practical to scatter several around the house for scene triggers

Reasons to hesitate

• needs a Bluetooth receiver in range: the Home Assistant host's own adapter, a Shelly Gen2+ or BLU Gateway proxy, or an ESPHome Bluetooth proxy
• Bluetooth range limits placement to roughly 10 meters from the nearest gateway
• useless without a home automation system to interpret the button events

Best for

• Home Assistant users who want cheap portable buttons for triggering scenes and automations
• bedside, desk, or entryway scene triggers without any wiring

Avoid if

• your Home Assistant host has no Bluetooth adapter and you do not want to set up a Bluetooth proxy (an ESPHome node, a Shelly Gen2+ device or the Shelly BLU Gateway)
• you want a button that works standalone with Alexa or Google Home without Home Assistant

Privacy and local-control notes

Bluetooth Low Energy button with no cloud dependency. Button presses are transmitted locally to a BLU gateway. No internet required.

Home Assistant support: supported · integration path: BTHome (official core integration, Local Push) via Home Assistant's Bluetooth integration: the host's own Bluetooth adapter, a Shelly Gen2+ or Shelly BLU Gateway Bluetooth proxy, or an ESPHome Bluetooth proxy.

Buying reality check

Price notes: Extremely affordable. Buy several for different rooms. The gateway is the real cost, but it is shared across all BLU devices.

The Aqara Wireless Mini Switch is the button I run and the one to buy first. Third Reality for the cheapest Zigbee, Zooz ZEN34 on Z-Wave, IKEA BILRESA on Thread. Plus Zigbee keypads for scene control and how to get clear feedback from a press.
