It appears the new styrbar firmware version breaks this driver. I posted about it here. IKEA STYRBAR pairing issues
I'm not expereinced enough to make a revised driver, but I'm going to give it a go slowly, unless someonce can point me to the issues?
The new fingerprint info is
infofingerprint profileId:"0104", endpointId:"01", inClusters:"0000,0001,0003,0020,1000,FC57,FC7C", outClusters:"0003,0005,0006,0008,0019,1000", model:"Remote Control N2", manufacturer:"IKEA of Sweden"
Any thoughts or similar experiences?
