[Tradfri] Commands don't change lightbulb [SOLVED]


I am trying to control my Tradfri lightbulbs with my freshly installed openHABian image. To connection through the binding seems to work but the bulb just doesn’t change its color/intensity.

What I did:

  • Install a fresh openHABian image (v1.6.2) automatically
  • Install Tradfri binding 3.0.0
  • Import gateway and enter security code (status -> ONLINE)
  • Import bulb (automatic ID | status -> ONLINE)
  • Link color/color_temperature channel to a newly created item

When I change for example the color settings of a bulb the log (frontail) shows following entries:

but the color doesn’t change. Same color temperatur etc. When I change the color through the IKEA app the same entry shows and the color changes. Just not through openHAB.

What I tried:

  • Deleting and newly inserting bulbs and/or gateway
  • Renaming blubs in the IKEA App, deleting the item and insert again (according to this post)
  • Reinstalling the binding
  • Rebooting the raspberry pi

My IKEA gateway and lightbulbs are up to date (gw: 1.12.34 | bulbs: 1.3.013)
openHAB 3.0.0 on a Raspberry Pi 4 4GB

I have made all the settings via the UI. Does anyone have/had a similar problem and knows what to do here?

After a gateway reset it worked…
