Context
At Smart & Green we designed cordless, rechargeable LED luminaires meant to be placed where cables cannot go: floating in swimming pools, hung high in trees, scattered across gardens and hotel terraces. Each luminaire is driven by a wireless control module.
The industry-standard way to pair a wireless device is to press a button on it while the controller listens. That works on a desk. It fails as soon as the device is out of reach — and for these products, being out of reach is the normal operating condition. Re-pairing a lamp after a controller change, a reset or the addition of a new lamp would mean fishing it out of the pool or climbing the tree.
The invention
The method lets the control module take the initiative, so that no action is ever needed on the device itself:
- The control module broadcasts a universal configuration signal that every unpaired device recognises.
- The signal is sent at reduced power, so only devices physically close to the controller answer. Proximity replaces the button press as the proof of intent, and neighbouring installations are not captured by mistake.
- Each unpaired device that receives the signal replies with its own unique identifier.
- The controller then sends a pairing request containing its own identifier, which the device stores. From then on it only obeys that controller.
The result is a pairing step that works through water, at height, and on any number of devices at once — without opening, touching or even seeing them.
Patent record
| Title | Appairage de dispositifs (Device pairing) |
| Inventors | Peter Wildhorn, Boris Dupoux |
| Applicant | IPW Europe |
| French priority | FR 12 57111, filed 23 July 2012 |
| International application | PCT/FR2013/051750, filed 19 July 2013 — published as WO2014016503 (30 January 2014) |
| French patent | FR2993731, granted 4 September 2015 |
The documents cited in the search cover remote binding of luminaires (Nedap), pairing of bidirectional home-automation objects (Somfy) and RF communication systems (SMK). The claims centre on the combination of a universal broadcast, a deliberately reduced emission power and an identifier exchange initiated entirely from the controller side.
Why it mattered
- It addresses the central field-support problem of a product line designed to be installed where people cannot easily reach.
- Proximity-based, controller-initiated onboarding has since become a common pattern in consumer IoT; this application describes it as of 2012.
- It sits alongside the second patent of the same venture, the modular LED luminaire (EP2532944).
