Like its sibling modules, the Bluetooth variant maintains a 0V DC baseline, eliminating battery replacements and external hardwired mains electrical lines.
The Kinetic Mechanism: A user's physical compression of a rocker switches an internal spring-loaded, over-center mechanics configuration. Once the structural pressure threshold is passed, the mechanism snaps instantly.
The Induction Yield: This rapid snap shifts a powerful micro-magnet across a high-density, stationary copper coil loop. The resulting instantaneous change in magnetic flux generates a voltage pulse yielding 120muJ to 210muJ (microjoules) of raw electrical energy.
Power Management Architecture: The brief electrical spike is routed directly into an onboard energy management sub-circuit. It is rectified, passed into a ultra-low leakage capacitor bank, and regulated down to a smooth DC voltage that powers the onboard 2.4GHz transmitter chip long enough to assemble and broadcast its data frames.
Because Bluetooth Low Energy networks typically require structured handshakes, this kinetic module utilizes a specialized "Advertising" protocol layout to broadcast commands instantly before its stored milliwatt/microjoule capacity drops below operational thresholds.
| Technical Parameter | Specification Value |
| Operating Frequency | 2.4 GHz ISM Band (2402MHz to 2480MHz) |
| Wireless Protocol Standard | Bluetooth Low Energy (BLE) / Bluetooth Mesh Compatible |
| Channels Utilized | BLE Advertising Channels 37, 38, and 39 (broadcasts across all three sequentially) |
| Modulation Scheme | GFSK (Gaussian Frequency Shift Keying) |
| Transmission Window | Data payload assembly and transmission finishes in less than 30 milliseconds |
| Signal Redundancy | Fires a rapid, un-connectable undirected advertising packet loop (up to 3-5 redundant telegram blasts) per mechanical actuation |
The module broadcasts standard BLE Advertising packets. Smart lighting controllers listening on the mesh intercept these raw advertising packets and read the secure payload embedded inside:
Static Hardware Signature: Every switch contains a unique, factory-assigned 48-bit Bluetooth MAC address. This MAC address acts as the hardcoded identity token inside the smart app configuration.
Rolling Sequence Counter: To prevent malicious intercept or "replay attacks" (where an unauthorized device captures a packet and rebroadcasts it later to turn lights off), the switch module increments a built-in 32-bit rolling sequence counter with every single click. If a receiver catches a packet with a sequence number lower or equal to the last one processed, it automatically discards it.
Payload State Encryption: The data frame (including button action states) is cryptographically signed using an AES-128 (Advanced Encryption Standard) key, ensuring total data security across your wireless lighting network.
The underlying transmitter module contains four physical contact nipples mapped as Channel A (Left Rocker) and Channel B (Right Rocker).
The specific choice of your Retrotouch glass paddle setup determines the software assignments inside your mesh app:
| Physical Rocker Assembly | Physical Action | Internal Contact Triggered | Ecosystem Translation (e.g., Casambi) |
| 1-Gang (Single Large Rocker) | Press Top Edge | Channel A: Nipple 0 | Target Node/Group: ON or Dim Up |
| Press Bottom Edge | Channel A: Nipple 1 | Target Node/Group: OFF or Dim Down | |
| 2-Gang (Split Dual Rockers) | Press Left Top | Channel A: Nipple 0 | Luminaire/Zone 1: ON or Toggle |
| Press Left Bottom | Channel A: Nipple 1 | Luminaire/Zone 1: OFF or Scene Recall | |
| Press Right Top | Channel B: Nipple 0 | Luminaire/Zone 2: ON or Toggle | |
| Press Right Bottom | Channel B: Nipple 1 | Luminaire/Zone 2: OFF or Scene Recall |
The 2.4 GHz spectrum provides highly responsive, high-bandwidth communication, but is more vulnerable to material density attenuation than lower sub-GHz frequencies. Structural installation design must align with the following behavior indices:
| Environmental Layer | Structural Attenuation Index | Practical Transmission Range |
| Open-Air Path / Clear Line of Sight | 0% Reduction | Up to 100 meters |
| Drywall / Standard Stud Walls | 10% to 30% Reduction | Up to 15 to 20 meters indoor mesh hopping distance |
| Brick / Reinforced Concrete / Glass Panels | 60% to 90% Reduction | Significantly diminished range. Relies heavily on a nearby mains-powered BLE node to repeat the signal. |
| Solid Metal Enclosures / Foil-Lined Drywall | 95% to 100% Reduction | Destroys RF path (Faraday Cage). The switch module must be surface-mounted or used in conjunction with plastic back-boxes. |
