Control your KNX and KNX Secure intallation via Node-Red! A bunch of KNX nodes, with integrated Philips HUE control and ETS group address importer. Easy to use and highly configurable.

# knxUltimateHueTemperatureSensor Node – Tutorial Outline

## 1. Intro (0:00)
- "Hi! Today we sync Hue temperature sensors with KNX via the `knxUltimateHueTemperatureSensor` node."
- "Use it for HVAC control, comfort monitoring, or energy dashboards."

## 2. Prerequisites (0:20)
- Optional `knxUltimate-config` gateway for ETS mapping.
- Required `hue-config` bridge credentials.
- Hue temperature sensor connected to the bridge."

## 3. Inputs & Outputs (0:40)
- Inputs: none.
- Output: single channel delivering temperature values using DPT `9.001` (°C)."

## 4. KNX Mapping (1:00)
- Choose the temperature GA; autocomplete filters to DPT `9.001` entries from ETS.
- Name the channel (auto-filled from ETS description).
- Confirm the DPT (list contains only temperature types)."

## 5. Hue Device Selection (1:35)
- Type the sensor name; autocomplete lists `rtype=temperature` devices.
- The Hue resource ID is stored automatically.

## 6. Startup Options & Node PINs (1:55)
- **Read Status at Startup**: request the current temperature after deployment so KNX receives an immediate reading."
- **Node PINs**: toggle visibility of the pins if you want to wire the output; hidden pins still emit messages."

## 7. Runtime Behaviour (2:20)
- Hue reports temperature in hundredths of a degree; the node converts to °C floating point.
- Emit messages ready for KNX writers, dashboards, or logic nodes."

## 8. Best Practices (2:35)
- Combine with `knxUltimateGlobalContext` to expose temperature globally.
- Use smoothing or hysteresis in your KNX logic to avoid rapid toggling.
- Tag node names with sensor location and mounting height."

## 9. Demo Ideas (2:55)
- Adjust KNX fan-coil speeds based on Hue temperature.
- Log room comfort data with `knxUltimateLogger` for analytics."

## 10. Wrap-Up & CTA (3:20)
- "We selected the gateway and bridge, mapped GA and DPT, and discussed best practices."
