Mr Smart iHost Rotary Controller

A local Node-RED node for SONOFF iHost / eWeLink CUBE that maps compatible Zigbee rotary knobs to one or more dimmable/CCT lights.

What it does

• Single press → group power toggle
• Rotate → brightness up/down
• Press + rotate → colour-temperature up/down on compatible targets
• One rotary knob can control multiple target lights
• Synchronized group mode keeps targets together
• Relative group mode preserves per-light differences
• Multi-target checkbox picker with Select All / Clear
• Per-target capability detection for CCT
• Local CUBE Open API + SSE; no cloud dependency for normal operation
• Installer-adjustable brightness and CCT step sizes
• Works with Node.js 16+ and Node-RED 3+

Tested hardware

• SONOFF iHost
• Tuya/MOES TS004F-compatible Zigbee rotary knob
• GLEDOPTO GL-C-006P CCT controller
• GLEDOPTO / iHost-mapped single-channel dimmer (tested as GL-C-009P profile)

Third-party Zigbee devices can expose incomplete or stale metadata through iHost. The node therefore keeps its own per-target state cache and tolerates incomplete brightness capability reporting.

Install on iHost (offline)

1. Open Node-RED on iHost.
2. Open Menu → Manage palette → Install.
3. Press the local package upload button.
4. Select the supplied .tgz file.
5. Install the package.
6. Restart the Node-RED add-on if prompted.
7. The Mr Smart → Rotary → Lights node appears in the palette.

First-time setup

1. Drag Rotary → Lights onto a flow.
2. Create/select an iHost configuration.
3. Enter the local iHost address.
4. Press Get Token, approve the request on iHost, then press Get Token again if required.
5. Deploy the iHost config once.
6. Reopen the Rotary node and press Refresh Devices.
7. Select one Rotary Knob.
8. Open Target Lights and tick one or more lights.
9. Select Synchronized or Relative group mode.
10. Adjust Brightness Step / CCT Step if needed.
11. Deploy.

Group modes

Synchronized

• Power: group is unified ON/OFF.
• Brightness: selected targets move to one shared brightness.
• CCT: compatible targets move to one shared CCT value.

Relative

• Power: each target toggles from its own current state.
• Brightness: each target moves by the configured step from its own current value.
• CCT: compatible targets move by the configured step from their own current value.

Defaults

• Brightness Step: 3%
• CCT Step: 15%
• Profile: Auto Detect
• Group Mode: Synchronized

Compatibility notes

The node is intentionally tolerant of third-party Zigbee devices whose iHost REST metadata is incomplete. Brightness commands are attempted on all installer-selected targets; unsupported targets fail independently without stopping the rest of the group. CCT commands are sent only to targets detected as CCT-capable unless a future profile explicitly overrides that behaviour.

Security

The iHost Open API token is stored as a Node-RED credential. Do not commit exported runtime credentials, tokens or production flow secrets to GitHub.

Development / release status

v0.3.0 is the first UI-polished multi-target test release. Validate on representative iHost firmware and mixed light-controller types before publishing as v1.0.0 or adding the node-red npm keyword for broad discovery.
