Not working on my side trying to bind IKEA Tradfri or Styrbar buttons to Tradfri light bulbs through ZHA.
Like I said earlier in this thread, I don’t use IKEA stuff so can’t help you with that. It would probably be helpful for others that could help you if you give some more information on what you have tried and what errors you are facing.
I tried what is written here and in that other thread: Can IKEA Lamp be controlled directly by remote and connect to ZHA?
