nearxos eab798cda4 Enhance Node-RED living room flow with new functionality and documentation updates

- Added a new "Living Room" tab to the Node-RED flow for better organization.
- Introduced functions for handling Home Assistant and Zigbee interactions, allowing for more dynamic control of living room lights.
- Updated the living room flow documentation to include configuration instructions for the Action node, improving usability for users integrating with Home Assistant.

This update enhances the functionality and clarity of the Node-RED integration for the living room setup.

Living Room flow – current analysis

Analysis of the Living Room tab as pulled from Node-RED (root@10.20.30.12) on the current flows.

Tab

Property	Value
Tab id	`7de41d810b04d992`
Label	Living Room
Nodes	12

Nodes (in flow order)

1. Inputs

Node	Type	Config	Out →
(unnamed)	trigger-state	Server: `29eb84a2708d96e0`. Entity: `input_boolean.living_room_new`. 2 outputs (allowed, blocked).	→ HA to NVL
(unnamed)	zigbee2mqtt-in	Server: `4e20fc347c658518`. Friendly name: Office Switch (TS0042).	→ Zigbee to NVL

2. HA → NVL path

Node	Type	Role	Out →
HA to NVL	function	ROOM_NAME = `cmd_livingroom`. Reads `msg.topic` / payload, sets `ha_lN_on` / `ha_lN_off` in `flow.nvlInState.rooms.cmd_livingroom`, outputs `buildAndSend`.	→ NVL SEND

3. Zigbee → NVL path

Node	Type	Role	Out →
Zigbee to NVL	function	ROOM_NAME = `cmd_livingroom`. Maps action (e.g. `1_single`) to `zigbee_swN`, sets state, `zigbeeClear`, `buildAndSend`.	→ 80ms, NVL SEND
80ms	delay	80 ms.	→ Clear zigbee edge
Clear zigbee edge	function	Clears `zigbee_swN` in state, sets `buildAndSend`.	→ NVL SEND

4. NVL send path

Node	Type	Role	Out →
NVL SEND	function	Builds payload from `flow.nvlInState` (roomNames with `cmd_livingroom`), struct_room_cmds.	→ link out 26

link out 26 → (cross-tab) → Flow 1 to UDP → udp out (PLC).

5. PLC → HA sync path (in Living Room tab)

Node	Type	Role	Out →
link in 14	link in	Receives from Flow 1 “from PLC states” link out (after nvl-receive).	→ NVL to HA Sync
NVL to HA Sync	function	Compares PLC light state to last; outputs only on change. Output 1 = turn_on msgs, Output 2 = turn_off msgs (`payload.action` + `payload.target.entity_id`).	→ two api-call-service nodes
(unnamed)	api-call-service	Action: `input_boolean.turn_on`. Entity: `input_boolean.living_room_new`.	—
(unnamed)	api-call-service	Action: `input_boolean.turn_off`. Entity: `input_boolean.living_room_new`.	—

        v
   link in 14 --> NVL to HA Sync --> Output 1 --> api-call-service (turn_on)
                                 --> Output 2 --> api-call-service (turn_off)

Notes

Zigbee device in this tab is Office Switch (TS0042); commands still go to cmd_livingroom (living room NVL). If the switch is physically in the office, you may want a separate room/flow or map it to another room in Zigbee to NVL.
NVL SEND matches the redesign: single list of rooms (roomNames), only cmd_livingroom for now; link out 26 sends to Flow 1 → UDP.
PLC → HA sync is in the Living Room tab: link in 14 gets PLC state from Flow 1, NVL to HA Sync outputs only on change, two api-call-service nodes with fixed input_boolean.turn_on / input_boolean.turn_off and input_boolean.living_room_new. With “Block Input Overrides” off, the sync’s msg.payload would override; if it’s on, the fixed entity is used (which matches the single current entity).
Flows file in the repo has been updated from this pull: docs/integration/nodered-flows.json.
