Unable to setup Ikea Styrbar remote with Sonoff ZBDongle-P

I need help!

I just picked up a Sonoff ZBDongle-P to connect to my Home Assistant Green and an Ikea Styrbar remote.

I set up the ZBDongle-P using ZHA. Now, when setting up the Styrbar remote, the remote appears and sometimes stays stuck on the interview process. Other times, it completes the interview and says ready to use. But then when I try and use it, it disconnects and trying to reconfigure it fails.

I can’t figure out what is going wrong.

I also tried setting up Zigbee2MQTT instead of ZHA but the final step in the setup always failed.

Any help is appreciated!
