Shutdown Octoprint after finished print

The plugin AutomaticShutdown (https://plugins.octoprint.org/plugins/automaticshutdown/) is great if you want to turn off your Printer after your print is finished. In my case I have the Octopi, the printer and a LED-lamp attached to a Fritz!Dect 200 remote controlled powersocket and configured it to turn itself off when the powerconsumption sinks below 12 Watts for 5 Minutes. So if the print is finished the autoshutdown-plugin shuts down the OctoPi. The socket detects the lower powerconsumption and shuts off itself off after the specified time… Save some energy here…

Raspi Babycam v3 with MotionEye

On the open source social network Mastodon I am following gnulinux.ch who brings up interesting news all around GNU/Linux. So gnulinux.ch has recently posted news about a release of the MotionEye Software which is a web-based frontend for motion. Usually motionEye and motion are used to record videostreams when motion is detected on one of the attached cameras. This is especially useful for security and surveillance cameras but I wanted to simply use MotionEye to show a videostream on a Website vor app and use it for a better version of my babycam v.1 and babycam v.2 MotionEye is using...
