Updated indi on both laptop and RPi3 (Ubuntu Mate 16.04) recently and on QHY9s doesn't work cooling (first it gave some unrealistic temperature in millions of degrees) and exposure, but without crashing.
QHY23 works fine except I can't set longer exposure than 86.4sec. Why now the arrows for changing exposure time are not in full seconds but in 0.001sec steps? That's pretty useless.
Fortunately I have other RPi3 with old INDI version where both qhy9 and qhy23 work fine including long exposure times. Affected small computer is actually my new Odroid XU4, seems to be a good replacement for RPi3 in computing power but I'm having trouble establishing hotspot (no internal wifi) and of course neither my DSO camera works there.
