KNX DateTime Sync

Overview

This driver is designed to broadcast the current time and date to the KNX bus using standard KNX Data Point Types:

• DPT_10 – Time (hours, minutes, seconds)
• DPT_11 – Date (day, month, year)
• DPT_19 – Combined DateTime + system flags (weekday, working day, DST, clock quality)

Note: You don’t need to use all three DPTs. The driver will only send those with a Group Address assigned.

This driver is ideal for using Control4 as the master time source for KNX, ensuring all KNX devices stay synchronized — without requiring additional external hardware like KNX time servers.

The driver supports multiple ways to trigger a broadcast:

• Manual action buttons
• Programming commands (e.g. using the Scheduler agent triggering)
• KNX bus read requests from a KNX device
• KNX Gateway coming online (e.g. after Control4 reboots or reconnects to KNX gateway)
• Automatic periodic sending (enabled via a driver property)

More information is provided on driver documentation. 

This is a free driver! The support is limited.
