IKEA L1531 control via MQTT
Integrate your IKEA L1531 via Zigbee2MQTT with whatever smart home infrastructure you are using without the vendors bridge or gateway.

To contribute to this page, edit the following file

IKEA L1531

| Model | L1531 | | Vendor | IKEA | | Description | SURTE door light panel, dimmable, white spectrum (38x64 cm) | | Supports | on/off, brightness, color temperature | | Picture | IKEA L1531 |

Notes

Pairing

Factory reset the light bulb (video). After resetting the bulb will automatically connect.

While pairing, keep the bulb close to the CC2531 USB sniffer.

What works is to use (very) short “on’s” and a little bit longer “off’s”. Start with bulb on, then off, and then 6 “on’s”, where you kill the light as soon as the bulb shows signs of turning on.

Device type specific configuration

How to use device type specific configuration

  • transition: Controls the transition time (in seconds) of on/off, brightness, color temperature (if applicable) and color (if applicable) changes. Defaults to 0 (no transition). Note that this value is overridden if a transition value is present in the MQTT command payload.

  • hue_correction: (optional) Corrects hue values based on a correction map for matching color rendition to other lights. Provide a minimum of 2 data sets in the correction map. To build a map:

    • choose one of your other lights to be the color reference
    • send a sample color to both lights (reference and non-reference)
    • modify hue value for non-reference light until it color matches the reference light
    • take note of the in and out values, where
      • in is the hue value you sent to your reference light
      • out is the hue value you had to dial your non-reference light to
    • repeat with a few other sample colors (4-5 should suffice)

    Example correction map:

    hue_correction:
    - in: 28
        out: 45
    - in: 89
        out: 109
    - in: 184
        out: 203
    - in: 334
        out: 318

OTA updates

This device supports OTA updates, for more information see OTA updates.

Manual Home Assistant configuration

Although Home Assistant integration through MQTT discovery is preferred, manual integration is possible with the following configuration:

{% raw %}

  - platform: "mqtt"
