C-ZB-RD1-Pro: Which 3-in-1 mode should I choose?
| Feature | Dimmer Mode (Default) | Remote/Smart Bulb Mode | Dual Purpose Mode |
|---|---|---|---|
| Firmware ID | C-ZB-RD1P-DIM | C-ZB-RD1P-REM | C-ZB-RD1P-DPM |
| Use Case | Smart control of traditional (non-smart) lighting circuit containing dimmable lights | Use as smart rotary remote for smart bulbs or other smart home devices. Keeps the wired circuit constantly powered (maintaining smart bulb connectivity). | Combines Dimming mode and Remote mode. Rotary knob is used as smart rotary remote for smart bulbs or other smart home devices. Hub independently controls wired lighting circuit. |
| Rotary Control | Knob. Controls brightness and on/off state of connected light circuit | Fully decoupled from circuit, sends smart commands to Zigbee hub. | Fully decoupled from circuit, sends smart commands to Zigbee hub |
| Wiring | Connected to traditional lighting circuit with non-smart bulbs | Option 1: Wired to lighting circuit with smart bulbs (constantly powered) Option 2: Wired to mains circuit using LED bypass as load | Connected to traditional lighting circuit with non-smart bulbs. (RD1P doesn’t physically switch circuit). |
| Bypass Requirements | Optional | • Optional when wired to smart bulbs circuit • Essential if wired to mains circuit without smart bulbs | Optional |
| Operation | Standard dimmer operation | • Wired circuit stays permanently energized • Rotary knob sends Zigbee commands to hub • Physical button presses trigger smart events • Smart bulbs are controllable via hub automations. | • Rotary knob sends Zigbee commands to hub (same as REM mode) • Physical button presses trigger smart events • Smart bulbs are controllable via hub automations. • Hub can independently switch/dim wired circuit |
| Zigbee Endpoints | 1: Endpoint 01 – Dimmable Light | 1: Endpoint 02 – Remote Control | 2: • Endpoint 01 – Dimmable Light • Endpoint 02 – Remote Control |
| Smart System Behaviour | Shows as a light with dimming capabilities | Identified as a remote; doesn't control wired circuit directly | Two entities created: 1. Smart dimmable light 2. Remote control |
| Device to Smart System Relationship | Knob and Smart Device (light) are synchronized | Fully decoupled from circuit. Sends StepUp/StepDown, MoveUp/MoveDown, single press, double press, hold, and release events to smart home system. | Fully decoupled from circuit. Sends StepUp/StepDown, MoveUp/MoveDown, single press, double press, hold, and release events to smart home system. |
| Specific Use Cases | Traditional smart dimming | Smart bulb control, scene activation, alternative device control. E.g. Use automations to control brightness of smart bulbs, or white balance. Or create complex automations to control multiple devices. | • Mixed lighting (smart bulbs + wired dimmable lights) • Scene control (rotary for smart bulbs, hub for traditional lighting). E.g. Use automations to control brightness of smart bulbs, or white balance. Or create complex automations to control multiple devices. Standard light setup |
| Button Sequence to Enter Mode | 3 short presses | 4 short presses | 5 short presses |
| LED Confirmation | Red LED flashes 6 times | Green LED flashes 6 times | Blue LED flashes 6 times |
C-RD1C: Why does my companion dimmer stop responding at max value?
Please try setting the maximum brightness of the dimmer
Setting Maximum Brightness:
- Start adjustment: 6 short presses + long 7th press
- LED confirmation: LED flashes green 2 times
- Adjust brightness: Turn rotary knob to 100% then lower it to a maximum level you are happy with (for example 95%)
- Save setting: 2 short presses
- Confirmation: LED stays solid green for 3 seconds
