Automation sunset turns on at noon

I have an automation I have set up for sunset. And it does trigger at sunset, but then it triggers the next day at noon, specifically 12:04PM. Has anyone seen this before? I am triggering two Insteon devices/ But only the one turns on at 12:04PM.

Seems like odd behaviour, have you checked that your home assistant location is set correctly (Settings > General).
If you post the YAML for your automation it would be possible for people here to check there isn’t some unintended trigger in the automation (when viewing your automation, the 3 dot menu in the very top right, edit in yaml). You might be able to get a clue to what is happing by looking at the automation traces too.

Share your properly formatted automation config.

Your automation contains actions to turn off a switch and a light. In your first post you said:

Which one, the switch or the light?

After today, none of them are working. They work manually but the above automation does nothing. And I’m confident I have my location correct now. Any suggestions?

Copy-paste the following template into the Template Editor and confirm the reported time represents sunset for your area.

{{ (state_attr('sun.sun', 'next_setting') | as_datetime | as_local).time() }}

Time was way off, so I mucked around with the zone settings and it seems to be working now.

Originally you said:

I’m confident I have my location correct now

After the template I suggested you use demonstrated your local sunset time was incorrect, you stated:

so I mucked around with the zone settings

So what was the original time zone setting (that you were confident was correct) and the new time zone that produces a correct sunset time?
