Dawn and Dusk to KNX

Configuration
1

I want to broadcast the Dawn and Dusk moments in time to KNX, were I used to control main phases of lighting: Day, Evening and Night.
The KNX Time-DPT is exclusively reserved for the actual time, so I want to express Dawn and Dusk in minutes form 00:00 using DPT time_period_min

I wrote the following configuration:

pack_astro:
  knx:
    expose:
      # Dawn in minutes after 00:00
      - type: time_period_min
        address: "0/4/0"
        entity_id: sun.sun
        attribute: sensor.sun_next_dawn
        value_template: >-
          {% set t = strptime(value, '%a %b %d %H:%M:%S %Z%z %Y') %}
          "{{ (t.hour * 60) + t.minute }}"

This runs fine, up to the value part. When I enter a fixed value, this will be broadcasted to KNX on a read request. However I don’t get any value regarding the next_dawn, so I can’t split the time into hours and minutes either. Logs are “Error rendering value template for KNX expose sun.sun__sensor.sun_next_dawn”.

What do I wrong?

Hi :wave:!

The attribute is next_dawn - without “sensor.”.

You may also send a time DPT by constructing a raw payload with knx.send - it should be straightforward… whatever fits your usecase best.
