Lambda Filter out bogus values during dawn

Is the character ( " ) or ( ’ ) missing in the script? I tried it now and it’s ok.

It compiles… now let’s see tomorrow morning :slight_smile:

I think today it worked. I keep watching it and report back.

Additionally I have 2 questions.

  1. Now when “the lambda” is in the is “no value”, can it send out 0 during tha time?
  2. during power loss/esp power down/esp unavailability the output in HA goes back to “no value” effective 0. How can I overcome that?

1,

      filters:
        lambda: |-
          auto sunrise = id(sun_sun).sunrise(-0.833);
          auto time = id(homeassistant_time).now(); 
          if(sunrise.has_value() && time.is_valid()){
            if((sunrise.value().hour * 60 + sunrise.value().minute + ${shift_sunrise}) < (time.hour*60+time.minute) && (time.hour*60+time.minute) < 1439) {  
              if(String(id(todaygen).state) == "nan") return 0;
              else return x;
            }
            else return 0;
          }  
          else return 0;

2,
I´m not sure, but it will doesn´t work probably.
