Philips Hue - bad request with API v2

Configuration
1

Hey folks. I’ll raise a bug too, but I was wondering if anyone else had seen the same thing?

Since installing 2021.12, I’ve been getting the below error(s) when triggering my automations to turn on the lights. Other errors are similar, but include different scripts that were called and different Hue api v2 URLS.

Thanks in advance … hoping it’s not just me! haha.

I have started to see this issue in 2021.12.0 and it is still present in 2021.12.1 using the Circadian Lighting custom component. I’ve opened an issue on the component page but this makes me think it may be a core issue.

So it turned out for me that in night mode via the adaptive lighting component, I had the min colour temp too low - it was set at a 1000 Kelvin. It seems that this in turn was lower than the Hues could go and would cause a 400 error. I upped the night time colour temp to 2000 and the error is gone, everything works again. Woo!

Big thanks to Marcel van der Veldt for helping me out via GitHub. :beer::beer::beer:

Same issue for me. Even making the call directly. Usually happening for rooms specifically.

Facing the same issue since my 2021.12 update. Is there any way to troubleshoot this problem?

I have a script which turns multiple Hue lights on by only setting the brightness. This now fails because of the 400 Baf Gateway response.
I’m kinda clueless as to what could go wrong there.
