Bug - Light hook using color tempurature is not working

[Jtaks]

Blueprint name

Hook - Light

Home Assistant Core Version

2026.3.1

Home Assistant Installation Type

Home Assistant Container

Description

color_temp which is used in the Hooks - Light blueprint was removed. This results in the lights not changing color temp when they did before the homeassistant upgrade. We should update the color_temp_kelvin data attribute value instead.

See 2026.3 release notes backward incompatible changes - Lights.

Automation YAML config

Hook - Light:

alias: Living Room Lights Hook
description: ""
use_blueprint:
  path: EPMatt/light.yaml
  input:
    controller_device: 8bd...696
    controller_model: IKEA E2001/E2002 STYRBAR Remote control
    light: light.living_room_lights
    smooth_power_on: false
    smooth_power_off: false
    light_color_mode: Color Temperature
    light_transition: 100
    brightness_steps_short: 5
    brightness_steps_long: 5

Controller - IKEA E2001/E2002 STYRBAR Remote control:

alias: Living Room Light Controller
description: ""
use_blueprint:
  path: EPMatt/ikea_e2001_e2002.yaml
  input:
    integration: Zigbee2MQTT
    controller_device: 8b...696
    helper_last_controller_event: input_text.living_room_switch_helper

To Reproduce

1. Run homeassistant 2026.3
2. Setup a light controller and light hook as described in the config
3. Attempt to change the color tempurature

Expected behavior

The light changes color temperature as it did before 2026.3.

Actual Behaviour

The light does not change color temperature.

Additional Details

• I'd like to help developing a fix for this issue.

Screenshots

No response

Additional context

Happy to take a stab at a fix but I would need some guidance around testing the changes (maybe with my local setup?).

Works well. Thanks @yarafie .

I suppose this repo is somewhat abandoned?

@Jtaks

Not sure if abandoned or not, but EPMatt Repo owner has not been here since last April 2025.
That's why I decided to revive my fork, fold in any PR's here, fix any reported issues here, add new controllers requested here into my fork.

EPMatt posted a vision of where he wanted to take his repo on the Home Assistant forums. I decided to implement some of his vision in my fork since I had time on my hands.

I'll try to do my best to keep this alive.
