Sunny when cloud suppression triggered

[mguyard]

Hello,

I don't have find information about this is_sunny attribute of sensor.adaptive_X_climate_status.
In this moment, is_sunny is true :

Confirmed by the card :

But i'm in a cloud suppression decision, so not a sunny day :

I've only enable the cloud percent entity :

This entity have a value of 90 actually.

state:
  translated: 90 %
  raw: "90"
  last_changed: "2026-05-06T12:12:12.424Z"

Is it a bug or i don't understand the is_sunny attribute ?
Thanks

Not a bug. is_sunny and the cloud coverage check are two separate, independent signals.

is_sunny tracks whether your weather entity's state matches the list of "sunny weather conditions" you've configured (like sunny, partlycloudy, etc.). It has nothing to do with the cloud coverage percentage sensor. Since you only configured the cloud percent entity — no weather entity with conditions — there's nothing for is_sunny to check against, so it defaults to true.

Cloud suppression fires when any of four signals indicate poor conditions:

• Weather entity state does not match the sunny conditions list
• Lux below threshold
• Irradiance below threshold
• Cloud coverage above threshold

In your case, that last one triggered (90% cloud coverage), which is exactly right. is_sunny being true at the same time just means "I have no weather entity to ask, so I'm assuming sunny" — it's not a contradiction.

If you ever want is_sunny to actually reflect sky conditions from a weather integration, you'd add a weather entity in the climate settings and select which states count as sunny. But for your current setup you don't need it — the cloud coverage path is working correctly.

For details, see the climate status sensor attributes section of the Entities wiki page.

Thank you. It's very clear and i've add the weather entity

Glad adding the weather entity sorted it. Just to close the loop for anyone who finds this later: is_sunny and the cloud coverage sensor are independent signals. is_sunny only checks whether the weather entity's state matches your configured sunny conditions list — if you haven't configured a weather entity, it defaults to true and never interferes with cloud suppression, which fires separately on the coverage percentage threshold.
