Struggling with sunrise/set and templating

Simple automation, except not… the latest in chicken coop comfort. Chickens leave the coop if it’s light out.

Outcome desired: turn on a heatlamp only when it’s dark and it’s cold. Otherwise keep it off.

If sun has set AND sun has not risen ' it's dark out AND
{{ state_attr('weather.my_house', 'temperature') | int<38}} ' it's cold
Then
Turn on switch.heatlamp
Else
Turn off switch.heatlamp

I’ve been all over the place trying to simplify and make it work. Multiple automations that check temp, sun, scripts, etc. The template evaluates true when it’s cold so that works. Right now I have an automation run every 60 min to test temp, then run a script to turn on the heatlamp for 59 min and then off. Then repeat. Uggg.

  - alias: ''
    data:
      entity_id: switch.022000095ccf7f6a4e91
    service: switch.turn_off

Any insights? Looking to learn here!
