How It Works

Kinetic energy in. BLE packets out.

Built on ILLUMRA/EBELONG kinetic switch technology, proven over 20+ years in commercial lighting worldwide.

01👆

Press

You press the button. That mechanical force is all it needs.

02⚡

Harvest

A spring-loaded electromagnetic generator converts your press into electrical energy.

03📡

Broadcast

The harvested energy powers a BLE 5.0 radio that broadcasts an advertisement packet.

04💻

Receive

Any BLE device within ~30m picks up the packet. Your code handles the rest.

FAQ

Common questions.

Each press compresses a spring-loaded electromagnetic generator inside the button. That mechanical energy is converted into enough electrical energy to power a BLE 5.0 radio and broadcast a single advertisement packet. This is the same proven kinetic energy-harvesting technology that has powered millions of commercial wireless light switches worldwide for over 20 years. The mechanism is rated for 500,000+ presses.
Anything with BLE 5.0 (or backward-compatible BLE 4.x) support. That includes NVIDIA Jetson boards, Raspberry Pi (3/4/5 with built-in BLE, or any Pi with a USB BLE adapter), ESP32 microcontrollers, laptops, phones, tablets, and Home Assistant setups using ESPHome BLE proxies. If it can scan for BLE advertisements, it works.
No. BLEButton uses BLE advertisement broadcasts, not connected-mode pairing. Your receiver simply listens for advertisements matching the BLEButton service UUID. No pairing, no connection handshake, no state to manage. This is also why multiple receivers can pick up the same button press simultaneously.
Fully. The BLE advertisement format, service UUIDs, characteristic UUIDs, and payload structure are published on GitHub under MIT license. You do not need our SDK to use BLEButton. If you prefer to write your own BLE scanner, the spec tells you exactly what to look for.
Each BLEButton has a unique device ID and an incrementing sequence counter in its advertisement payload. Your code can validate device IDs and detect replayed packets via the counter. For high-security applications, we recommend running your receiver in a controlled RF environment or adding application-layer authentication. The protocol spec documents the security model in full.
BLEButton is the first physical trigger built for NVIDIA’s OpenClaw robotic manipulation framework. Press the button and your Jetson sends a natural language prompt to the NemoClaw model, which plans and executes the robotic action. The Python SDK handles BLE scanning, event parsing, and OpenClaw integration. Three lines of code from button press to robot movement.
We are targeting Q3 2026 for initial shipments. The kinetic switch mechanism is proven manufacturing with over 20 years of production history. The BLE radio design is finalized. We are currently in tooling and certification. Backers will receive regular production updates throughout the campaign.
Yes. Each button broadcasts a unique device ID. Your code can listen for multiple buttons simultaneously and route different actions to each one. The SDKs support filtering by device ID, so you can assign distinct behaviors to each button. There is no practical limit to the number of buttons a single receiver can monitor.
From the Founder

Built by someone who ships hardware.

JE

Jared Eggett

Founder, Ad Hoc Electronics

I've always dreamed of being an inventor. That dream led me to spend 20+ years in hardware manufacturing, building kinetic energy-harvesting switches and earning multiple utility patents along the way. BLEButton is the product I've wanted to build my entire career — taking proven self-powered technology and putting it directly in the hands of developers. No batteries to replace. No cloud to depend on. Just a physical trigger that speaks BLE and lets your code do the rest.
