Date/Time configuration

The KNX DateTime node writes the current date/time to one or more KNX group addresses.

It supports:

  • DPT 19.001 (DateTime) โ€“ recommended
  • DPT 11.001 (Date) โ€“ optional
  • DPT 10.001 (Time) โ€“ optional

Group addresses

Purpose Property DPT
DateTime DateTime GA (gaDateTime) 19.001
Date Date GA (gaDate) 11.001
Time Time GA (gaTime) 10.001

You can configure just one GA (typical) or multiple GAs (the node writes to all configured destinations).

When it sends

  • On deploy/startup (optional) with a configurable delay.
  • Periodic send (optional) with seconds/minutes interval.
  • On input (always): each incoming message triggers a write.
  • Editor button: send-now.

Input payload

If msg.payload is missing/empty, the node sends the current system date/time.

Supported values:

  • Date object (new Date())
  • timestamp number (milliseconds since epoch)
  • string accepted by new Date("...")
  • "now"

Node output

The node emits one message per send:

  • msg.payload: the Date written
  • msg.sent: array of { ga, dpt, name }
  • msg.reason: input, startup, periodic or button

Editor auto-fill (ETS)

When you add a brand new node, it can auto-select the first KNX Gateway that has an ETS import and pre-fill coherent group addresses.
