IKEA KAJPLATS Smart Bulb Zigbee Pairing Mode Power Cycle

bonesderdritte · February 19, 2026, 1:35pm

This blueprint provides a reliable power-cycle helper for IKEA KAJPLATS smart bulbs.

It allows you to trigger:

• 6 cycles → Factory reset / start new Zigbee pairing
• 12 cycles → Switch from Matter mode to Zigbee mode (legacy Zigbee)

The blueprint:

• Ensures a clean OFF start
• Uses exact ON-event counting (no off-by-one issue)
• Leaves the bulb powered ON at the end
• Works with smart plugs or relays
• Tested with Zigbee2MQTT

Important:
“Cycles” means how many times the bulb is powered ON (OFF → ON).
Example: cycles = 6 results in exactly 6 ON events total.

Tested with:
IKEA KAJPLATS bulbs
Home Assistant
Zigbee2MQTT

Fantastic blueprint — using a Home Assistant automation on a smart plug to put IKEA bulbs into pairing mode is a huge time saver. Instead of standing next to a lamp counting switch flips, just let HA do the work.

Hardware setup

Wall outlet 220V → Smart plug (HA controlled) → Lamp (E27 or E14 socket) → IKEA bulb

Works with any lamp that has a 220V plug. Use an E27 lamp for E27 bulbs, or a smaller table lamp with an E14 socket for E14 bulbs. Plug the lamp into a smart socket that is already available in Home Assistant:

The smart plug becomes your virtual switch — no wall switch involved at all.

Step 1: Import the Blueprint

Set “Target Switch Entity” to the smart socket you want to control
Hit SAVE

Step 2: Let HA search for new Zigbee device

For ZHA: Add device
For Zigbee2MQTT: Permit join

Step 3: Open blueprint, set Number of ON events (OFF → ON), then run script

For older IKEA TRÅDFRI bulbs like E27 WWT
- In the blueprint, set Number of ON events (OFF → ON): to 6
  - Run script and wait
    - When script is finished successfully, the bulb will blink warm white = confirmation it is in pairing mode
Newer IKEA KAJPLATS (requires 2 sequences)
- Phase 1: Number of ON events (OFF → ON): 6
  - Bulb should then blink warm white = confirmation that it is reset
  - Wait 10 seconds
- Phase 2: Number of ON events (OFF → ON): 12
  - Bulb should flash cold white = Zigbee pairing mode

Step 4: Wait for HA to discover the bulb

Once the light bulb is discovered, name it and SAVE.

Step 5: Put your bulb into place

Unplug the lamp.
Unscrew the bulb.
Install the bulb in the desired location.
Control it from HA!

Timing settings in the blueprint

A short ON interval of about 700 ms combined with a longer OFF interval of about 1500 ms seems to work better than equal on/off times. Even if the bulb does not visibly light up with a 700 ms ON window, it still counts the ON/OFF events and can enter pairing mode. Test and post what settings work best for your hardware.

Feature suggestion for the blueprint: Bulb type selector

It would be really useful if the blueprint offered a selector at the top:

Old IKEA Zigbee bulb (Trådfri etc.) → runs Phase 1 only (6 cycles)
New IKEA Matter bulb (Kajplats) → runs Phase 1, 10 sec delay, runs Phase 2 (6 + 12 cycles)

This would make the blueprint a universal IKEA bulb pairing tool, covering both past and present bulbs. Would you be open to adding this? Happy to help test if useful.
