2. Configure data to send on KNX bus

Select which DPT (datapoint type) you want to send to KNX bus.

You can select between:

  • Send Time - DPT 10.001 - 3 bytes, sends day, hour, minute, seconds to the bus
  • Send Date - DPT 11.001 - 3 bytes, sends day, month, year to the bus
  • Send Day/Night - DPT 1.024 - 1 bit, sends 0 (Day) or 1 (Night) to the bus. The value changes with sunrise and sunset calculated based on your configured location

Now you pick a group address and select an interval of sending the value to the KNX bus.

Can other KNX devices read those values on demand?

Besides sending the values cyclically at a specified interval, if another KNX device sends a Group Read request, the KNX Time Server will also reply with the current value.
