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
HI EVERYONE!
TODAY WE EXPLORE THE KNX ULTIMATE NODE.
THIS IS THE MAIN KNX DEVICE NODE INSIDE NODE RED.

WHEN TO USE
DROP IT INTO ANY FLOW THAT MUST LISTEN TO OR CONTROL A KNX GROUP ADDRESS.
IT HANDLES READ, WRITE, AND RESPONSE TELEGRAMS.

INPUTS AND OUTPUTS
ONE INPUT ACCEPTS NODE RED MESSAGES HEADING TO KNX.
ONE OUTPUT EMITS TELEGRAMS FROM THE BUS.
RBE ICONS SHOW WHEN FILTERING IS ACTIVE.

CORE SETUP
SELECT YOUR KNX ULTIMATE CONFIG SERVER.
TYPE THE GROUP ADDRESS OR SWITCH TO LISTEN ALL GA.
SET THE OUTPUT TOPIC IF YOU NEED A DIFFERENT ONE.
PICK THE RIGHT DATAPOINT TYPE.
GIVE THE NODE A FRIENDLY NAME.

COMMUNICATION OPTIONS
DECIDE IF THE NODE SENDS AN INITIAL READ.
ENABLE OR DISABLE NOTIFY ON READ REQUEST, RESPONSE, OR WRITE.
TURN ON AUTO RESPOND WITH A DEFAULT VALUE IF REQUIRED.
CHOOSE THE OUTPUT TYPE, WRITE, RESPONSE, OR READ.
OPTIONALLY TURN ON PASSTHROUGH.

FILTERING AND FORMATTING
USE OUTPUT RBE OR INPUT RBE TO DROP DUPLICATES.
APPLY MULTIPLY, NEGATIVE HANDLING, AND DECIMAL PRECISION.
THE LISTEN ALL GA OPTION CAPTURES EVERY TELEGRAM FOR CUSTOM LOGIC.

FUNCTION HOOKS
EDIT THE SEND MESSAGE SCRIPT TO TRANSFORM OUTGOING PAYLOADS.
EDIT THE RECEIVE MESSAGE SCRIPT TO ENRICH INBOUND DATA.
LEVERAGE THE SNIPPET PICKER FOR COMMON PATTERNS.
CHECK THE SAMPLE EDITOR FOR DPT HELP AND EXAMPLES.

SECURE GROUP ADDRESSES
WHEN THE CONFIG NODE HAS A KEYRING, SECURE GAS ARE FLAGGED.
THE ICON SWITCHES TO A SHIELD WHEN GA SECURE IS TRUE.

BEST PRACTICES
ALWAYS MATCH THE DPT TO THE DEVICE.
USE RBE TO REDUCE CHATTER.
SET A DEFAULT RESPONSE VALUE FOR RELIABLE READ REPLIES.

EXAMPLE WORKFLOW
DEMO ONE: READ A TEMPERATURE SENSOR AND PUBLISH TO MQTT.
DEMO TWO: TOGGLE A LIGHT WITH A SIMPLE INJECT NODE.

WRAP UP
WE CONFIGURED THE DEVICE NODE AND CUSTOM SCRIPTS.
NEXT TIME WE WILL COVER ANOTHER NODE FROM THE SUITE.
