Unfortunately it not working for me binding IKEA Tradfri or Styrbar buttons to Tradfri light bulbs through ZHA. Green mark shows for a second then disappear. No binding established.
Not claiming I understand what is going on, but @rockbruno 's instructions did not work for me. However, I did eventually get it working. The final step I did that made it work was holding the pairing button on the remote while it was next to the tradfri block for ten seconds. This was after I had paired the lights and then the the remote to ZHA.
I also tried previously only holding it down for four seconds (which was enough to get the lights to dim), but that didn’t seem to do it. I also made sure that when I initially paired the remote I did it using the “Add devices via this device” option on the tradfri lights:
Not sure if any of the specific things I did mattered, or if it was just flakiness.
This instruction is just great. Thank you for your work. It was also helpful in 2024 for TRETAKT from IKEA with ZHA and Remote Control. Works perfectly!
