Thanks for your reply. lircd seems to be started by OSMC, thus I can’t stop it. During my tests OSCM once didn’t show anything but was running (including lircd). I could stop/start it afterwards. Hope that was an exceptional situation since my second try was successful.
Similar hope is that the harmony will do a safe switch between both bluetooth devices involved (fire tv and keyboard). It worked till now, but failed once after reconfiguration of the harmony device fire tv.
