Kelvin doesn't go below 2500k when set to 2200k and bulb supports it.

Even though I set lowest to 2200k and sleep mode to 2200k, it never drops below 2500k, works fine in Tapo app (using tapo bulbs).

Are you sure your light has that in the attributes?

What does it report in the Developer Tools attributes?

e.g.,:

K = 1000000 / mired

So for me, taking:

min_mireds: 150
max_mireds: 500

minimum: 1000000 / 500 = 2000 K

Can you check your values?

[IIV-NATHAN-VII]

How odd, it shows the min as 2500, I wonder if it's a limitation of the Tapo integration I'm using

min_color_temp_kelvin: 2500
max_color_temp_kelvin: 6500
min_mireds: 153
max_mireds: 400
supported_color_modes:
  - brightness
  - color_temp
  - hs
  - onoff
friendly_name: Living
supported_features: 0
color_mode: color_temp
brightness: 255
color_temp_kelvin: 2906
color_temp: 344
hs_color:
  - 27.987
  - 59.51
rgb_color:
  - 255
  - 174
  - 103
xy_color:
  - 0.505
  - 0.385

[IIV-NATHAN-VII]

So I just did an override in my config:

homeassistant: customize_domain: light: min_color_temp_kelvin: 2200 max_color_temp_kelvin: 6500

Shows in Developer Attributes. min_color_temp_kelvin: 2200 max_color_temp_kelvin: 6500 min_mireds: 153 max_mireds: 400 supported_color_modes:

• brightness
• color_temp
• hs
• onoff color_mode: color_temp brightness: 102 color_temp_kelvin: 2500 color_temp: 400 hs_color:
• 28.874
• 72.522 rgb_color:
• 255
• 159
• 70 xy_color:
• 0.546
• 0.389 friendly_name: Living supported_features: 0

Still only sets 2500.

[basnijholt]

I think this is due to the max_mireds: 400, you should set that to

max_mireds = 1000000 / 2200 = 454

This is because Home Assistant computed the min_color_temp_kelvin based on the mireds (I believe).

[IIV-NATHAN-VII]

After a bit of digging I think it's something else, I can see it changing on the Tapo app when I toggle sleep mode on/off, I can also see it sending 2200K in the log now, but my bulbs don't seem to want to go below 2500k unless set in the app, I will check the Tapo integration, thank you for your time.

[IIV-NATHAN-VII]

Can I ask, if I put all my bulbs in a group and 2 of my 10 bulbs only go to 2500k (not 2200), would that also limit the others to 2500k?

Thanks.

If you put them in a Home Assistant light group, AL will expand them and treat them separately. So it won't limit the others.
