THIS was THE important missing piece! With this IKEA Trådfri Shortcut button it’s not very easy to press & hold the reset button on the inside while NOT simultaneously pressing THE button, too!
So, be careful and JUST press the reset button for app. 30 seconds.
It helped me, too. No need for an IKEA bulb or some account or the IKEA base station or a firmware update – at least for me.
Thank you!! This did the trick to restore button click sensing.
Can confirm this also worked for me with a shortcut button purchased around May 2023.
After pairing I could not see any zha_event in developer tools, despite the fact that when I hit the ‘identify’ button in HA the device would flash.
After holding down the pairing button for 30 seconds it started to appear in zha_event and could be used for automations.
