And again after two days the mirror did what he wants . I was nearly at that Point to throw all away and start fom beginning. Baut then i tried a thing , I disabled Bluetooth AND WLAN. And did it that way:

//sudo nano /etc/modprobe.d/raspi-blacklist.conf

blacklist brcmfmac
blacklist brcmutil
blacklist cfg80211
blacklist rfkill
blacklist btbcm
blacklist hci_uart

And after that a Reboot and

//sudo systemctl disable hciuart

and another reboot .

This works, I hope longer then 2 Days ;)

Now I have to work with the Ethernetport and gonna try it with an USB Wlan Dongle

@Damian no prob. im learning from reading and asking?

@Damian I did after i checked the PIR a new npm install in the MM-PIR-Sensor Folder and changed the Sensor Pin to 25 (its the GPIO PIN) wrong thinking thats why I am a Noob ;)

Problem solved :)

Now that I deleted and reinstalled the module a new problem shows up . After I put the code In my config.js the Monitor stays black after the reboot. I testet the PIR its not broken.

@Damian Thank you, now I got me a Ferrit Bead but it still dont not work. Maybe my coding or my cabling is wrong.

//		{
		module: 'MMM-PIR-Sensor',
		config: {
			// See 'Configuration options' for more information.
	sensorPIN: 22,
                                powerSaving: true
                        }
                },

And again me ;). I can not see how my MagicMirror can work so far with my ignorance ok not really Ignorance but Noob, Noob, and for Luck I got Help from her e (THX Mykle1). But now I dont now what really happend, Ihave an PIR 501 and worked really fine with the Module MMM-PIR-Sensor. But now after I put all together in my Frame the Monitor goes off after 2 minuets but turns on b himself after ca. 30 seconds.That never happend befor I had it “free air”. Ok maybe its one or athe module wiche works not together. BTW. I am using a Raspbery PI 3. Edit the Monitor now doesnt turn off :(

@strawberry-3.141 Ok. thats could be a way. Ill try It. thank you for that tip.

@strawberry-3.141 Its not possible to split the Calendar because all 3 Persons have to manage the meetigs or the Dates… Or is my way of thinking wrong? Im a noob;)

@strawberry-3.141 ok, thank you for the information.also it would not be possible to change the colour depending on the content?or am I wrong
