This is down to changes in Home Assistant 2026.3, you most likely have color_temp used in HA automations. color_temp has been depreciated and you need to change the automation yaml to color_temp_kelvin

See: https://developers.home-assistant.io/blog/2026/02/23/remove-deprecate-light-features/

...you most likely have color_temp used in HA automations...

No, I do not use color temp in any automation.
I receive this log every 1-2 min (availability interval).

Are you using HA 2026.3?
