Hyperion stops working

MikeOO · 29. Oktober 2017

My Hyperion Setup stops working, about every 3 days. The leds are still on, but in "background lightning" mode. It seems like the grabbing stopped, but thats just my guess.

Hyperion-app at android still works. The rpi itself works, i can ssh into it.

Only solution so far: wait one night, without powering the rpi.

What i tested already:

killall hyperiond and restart
resetting usb device (the grabber or the atmo) with a script

EDIT: when i take a screenshot of the grabber i just get a thin green line.

Any Help?

Not a single idea? What means "Failed with result 'signal'"

I think this bit from the log is indicating that the USB grabber is having trouble.

My guess would be it's dying a slow death.

I noticed on the USB grabber I bought for my system ran very hot. I cracked it open and cut a hole in the casing, then I put a heatsink on the main chip to dissipate the heat.

My mess. You can see the grabber in the picture, it has a butchered hole in it with the heatsink. It's been running 24/7 since last April.

Just one idea, hope it helps.

Thanks, i already thought in this direction but didnt expect to achieve anything. Your experience encouraged me, thanks. Gonna try this.
