Time-dependent dim level

Hello everyone

I am brand new to Home Assistant.
Until now, I have controlled my smarthome based on openHAB and switched to HA last week.

I had a rule in openHAB that calculates the time between sunrise and sunset and sets a default dimming level that is set when KNX connected lamps are switched on.
To make things even more complicated, I had a group in openHAB to which the dim level is set. If a lamp is now switched manually, it is removed from this group until it is switched off.

Now I’m trying to map the same thing with HA and have also consulted the AI, but I’m not really getting anywhere.

This are the automations, I built:

          {% set total_daylight = sunset - sunrise %}
          {% set elapsed_daylight = now - sunrise %}
          {% set brightness = 90 - (80 * (elapsed_daylight / total_daylight)) %}
          {{ brightness | int }}

But it didnt trigger.
Where is my think-error?

Hi,
have you had a look at Adaptive Lighting?

If I understand you correctly this should be an easier solution to your automation?

Hey Gregor

That looks really interessting. I will take a look on that.
