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.

INTRO
WELCOME BACK!
TODAY WE CONFIGURE THE KNX ULTIMATE GLOBAL CONTEXT SERVICE.
IT SYNCs KNX VALUES WITH NODE RED GLOBAL VARIABLES.

PURPOSE
USE IT WHEN YOU NEED DASHBOARDS OR FLOWS TO READ KNX DATA WITHOUT WIRING EVERY DEVICE.
OPTIONALLY PUSH CHANGES BACK TO THE BUS FROM ONE CENTRAL PLACE.

IO OVERVIEW
NO INPUTS, NO OUTPUTS.
ONCE DEPLOYED IT RUNS IN THE BACKGROUND.

CORE SETUP
SELECT THE KNX ULTIMATE CONFIG GATEWAY.
TYPE A NAME MADE OF LETTERS ONLY.
CHOOSE WHETHER THE VARIABLE IS READ ONLY OR READ WRITE.

WRITE INTERVAL
PICK HOW OFTEN GLOBAL CHANGES ARE FLUSHED TO KNX.
OPTIONS RANGE FROM TWO HUNDRED FIFTY MILLISECONDS UP TO TWO SECONDS.

CONTEXT STORAGE
LEAVE BLANK FOR DEFAULT STORAGE.
OR SPECIFY FILE, MEMORY FILE, OR ANY PERSISTENT CONTEXT STORE.

HOW IT WORKS
THE NODE SUBSCRIBES TO TELEGRAMS.
INBOUND VALUES UPDATE THE GLOBAL VARIABLE AUTOMATICALLY.
WHEN FLOWS WRITE TO THE VARIABLE, THE NODE SENDS KNX TELEGRAMS AT THE NEXT INTERVAL.

SAFETY TIPS
USE READ ONLY MODE IF OTHER FLOWS SHOULD NOT MODIFY KNX DEVICES.
IF YOU ALLOW WRITES, DEBOUNCE FAST CHANGES TO AVOID BUS FLOODS.
DOCUMENT THE VARIABLE NAME FOR YOUR TEAM.

DEMO IDEAS
EXAMPLE: MIRROR HEATING TEMPERATURES INTO GLOBAL CONTEXT FOR DASHBOARDS.
EXAMPLE: UPDATE A GLOBAL SCENE FLAG FROM A VOICE ASSISTANT.

WRAP UP
WE CHOSE THE GATEWAY, EXPOSURE LEVEL, AND WRITE INTERVAL.
