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.

# knxUltimateHuedevice_software_update Node – Tutorial Outline

## 1. Intro (0:00)
- "Welcome! This video covers the `knxUltimateHuedevice_software_update` node, which exposes Hue device firmware update status to KNX."
- "Ideal for maintenance dashboards and service alerts."

## 2. Prerequisites (0:20)
- Optional `knxUltimate-config` gateway. 
- Required `hue-config` bridge with credentials.
- Hue device that reports `device_software_update` resources (lights, plugs, accessories)."

## 3. Inputs & Outputs (0:45)
- Inputs: none.
- Output: single boolean payload indicating whether an update is available/required."

## 4. KNX Mapping (1:00)
- Select the GA to represent update status (`1.xxx`). Autocomplete filters to boolean DPTs.
- Name the GA (e.g., “Kitchen Lamp Update Pending”).
- Choose a DPT (switch/binary)."

## 5. Hue Device Selection (1:30)
- Autocomplete lists `rtype=device_software_update` resources.
- Once selected, the Hue resource ID is stored to track that device."

## 6. Startup Options & Node PINs (1:50)
- **Read Status at Startup**: retrieve the current update flag immediately after deployment so dashboards stay accurate."
- **Node PINs**: toggle the output pins if you want to wire the message into additional flows; hidden pins still emit updates."

## 7. Runtime Behaviour (2:15)
- Hue state `up_to_date`, `available`, or `required` is mapped to boolean values (true = update available/required).
- Use with `knxUltimate` writer nodes or context logic to notify maintenance staff."

## 8. Best Practices (2:40)
- Pair with `knxUltimateAlerter` to send reminders until updates are applied.
- Tag nodes with device location and type to ease maintenance.
- Consider storing status in global context for dashboards."

## 9. Demo Ideas (2:55)
- Flash an LED on a KNX touch panel when Hue fixtures need firmware updates.
- Log update history with `knxUltimateLogger` for compliance reports."

## 10. Wrap-Up & CTA (3:20)
- "We linked Hue and KNX, mapped update statuses, and suggested alert workflows."
- "Subscribe, like, and share how you handle firmware management!"
