I had the same issue as Knud (I'm using Octo too) on X16 version (still have not met it on X17 though) - after reboot everything works fine and then suddenly sensors stops working, restarting the service does not help, only reboot helps. It's a random bug - might happen once a day or every half an hour.. Also starting from X17 version I faced another bug with my Octo: after turning on the PC\reboot my RGBpx are swithched on even if they were manually turned off before powering off my PC\reboot (...
