From c049a28c97779ea94e40ce77db4e3c2db0a6f29c Mon Sep 17 00:00:00 2001 From: nearxos Date: Sun, 8 Feb 2026 17:49:07 +0200 Subject: [PATCH] Implement global room configuration for Node-RED integration - Introduced a single global room configuration file to streamline the management of rooms and lights, reducing redundancy in configuration. - Updated various integration scripts to utilize the global configuration, enhancing maintainability and clarity. - Improved documentation to reflect the new configuration approach, including instructions for loading and modifying the room configuration. This update simplifies the integration process and improves the overall user experience for managing lights and rooms in Node-RED. --- docs/integration/all-lights-and-rooms.md | 14 ++++ docs/integration/ha-to-nvl-function.js | 17 +++-- docs/integration/nvl-to-ha-sync-livingroom.js | 9 +-- docs/integration/state-to-nvl-send-payload.js | 6 +- docs/integration/zigbee-to-nvl-function.js | 9 ++- node-red/room-config-loader.js | 13 ++++ node-red/room-config.js | 69 +++++++++++++++++++ 7 files changed, 118 insertions(+), 19 deletions(-) create mode 100644 node-red/room-config-loader.js create mode 100644 node-red/room-config.js diff --git a/docs/integration/all-lights-and-rooms.md b/docs/integration/all-lights-and-rooms.md index ae40154..338106e 100644 --- a/docs/integration/all-lights-and-rooms.md +++ b/docs/integration/all-lights-and-rooms.md @@ -4,6 +4,20 @@ This doc explains how to scale the working “test light” setup to **all your --- +## 0.
