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 BLU gateway to bridge it into HA, 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

• requires a Shelly BLU gateway or ESPHome BLE proxy — cannot talk to Home Assistant directly
• 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

• you do not have a Shelly BLU gateway or ESPHome BLE proxy set up
• you want a button that works standalone with Alexa or Google Home without Home Assistant

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.
