Thanks a lot for the fast answer. Unfortunately the external power unit (PSU) is not the problem. I've already measured it and the current/voltage curve looks like it's new device :-)
I guess, it's more of an internal power supply that is not stable. Or actually the contacts of the battery. I just put slight pressure from above and the controller started up smoothly at least. Now a small piece of cardboard is between the housing and the battery and let's see what happens. lms: 8.2.0 - 1620914398 @ thu may 13 16:14:44 cest 2021 on rpi4/ raspbian buster 10 points (nfs) to musiclibrary on qnap ts212 1x duet - cntrl-fw: 8.0.1-r16855/ receiver-fw: 77 2x sb radio - fw: 8.0.1-r16855 1x squeezebox boom - fw 57 1x transporter - fw: 87 rpi 2b - pcp 7.0.1/ squeezelite v1.9.9-1386-pcp softsqueeze 3.9.2 on win 10 / squeezeplay 8.0.1r1343 on win 10 squeeze player 1.3.21 on s7/android 8.0.0 controller: android phone - squeezer 2.4.4/ material skin 2.3.5 ------------------------------------------------------------------------ MichaelPr's Profile: http://forums.slimdevices.com/member.php?userid=68465 View this thread: http://forums.slimdevices.com/showthread.php?t=114654 _______________________________________________ Duet mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/duet
