Issue
HA: 2025.3.1
I can see the color temp within Zigbee2mqtt
But in Home Assistant, its all reported as null
I can still control the color temperature via HA light card, but, once you navigate away and back again, there is no value on the slider
I’ve restarted both HA and Z2M. Logs show payload of color temp being sent within zigbee2mqtt (makes sense as I can control it). Not sure of what other logs and where I can be looking to further troubleshoot this issue. Thank you

### What happened?
https://www.zigbee2mqtt.io/devices/404006_404008_404004.html… stopped showing value of `color_temp` sensor attribute, (it's always `null`) after update HA to 2025.3.
```
min_color_temp_kelvin: 2702
max_color_temp_kelvin: 6535
min_mireds: 153
max_mireds: 370
effect_list: blink, breathe, okay, channel_change, finish_effect, stop_effect
supported_color_modes: color_temp
effect: null
color_mode: color_temp
brightness: 255
color_temp_kelvin: null
color_temp: null
hs_color: null
rgb_color: null
xy_color: null
friendly_name: Bulb
supported_features: 44
```
However MQTT message contains proper `color_temp` value. Color temperature can be set precisely via HA color temp control, but not via `color_temp` sensor attribute as I did within automations.
Z2M 2.1.3
HA 2025.3.0

with the last reply in the thread being someone that has raised the issue with home-assistant/core (here )
Will try to revert to 2025.2.5 and report back.
Edit: didn’t end up reverting as I have yet to do a rollback since starting my HA journey and wasn’t sure how comprehensive it needed to be etc. however seems might be getting patched in a timely manner based on this post
Edit 2: solved with update
