MMM-Globe for the animated background image.

Thanks for the info about your used modules.
I have also the PI4 but MMM-globe stops working within 25% of memory.

Somehow with the time the RAM is fulling up by itself. Have no idea why. I also use pages and indicator.

@foxy25 How are your temperatures? I had to add a “special” encasing for the PI. About 14 Euros at Amazon.

One hint (mybe its useful for you: I changed soe code inside the “MMM-WiFiPassword” module. It was a bit annoying that below the QR-Code was still “Network” hardcoded.
I changed the text in “MMM-WiFiPassword.js”, row 76 to

networkNameDiv.innerHTML = "<b>WLAN:</b> " + this.config.network;

looks nicer.

Hi,

hmm yes, maybe there are some litte problems with the MMM-Globe module.

In my case I have the Pi4 4GB Model, runs stable, but somehow with the time the swap-space going more full and fuller and when its reached the limit (in my case 512mb) the Pi will go very slow.
After a reboot everything goes allright and workes well…
With the rest of the memory, i have no trouble:

Free Ram = 25-30%, without the module round 44%

Maybe it is better to run in production the 8Gb Model?

My temperature is around 50-54° C with the fanless case.

Without the globe modul around 48°C

I change the name from “Network” to “WLAN- Gastzugang”.

Hi
Today my WIFI-Powerplugs are arrive.

https://www.ebay.de/itm/BlitzWolf-SHP6-TASMOTA-9-3-1-wie-Gosund-SP111-3450W-WLAN-Steckdose-Strommessung/274600948644?hash=item3fef7df3a4:g:DaMAAOSwvWNgR1NQ

I used Tasmota because it don’t send things “Home” and you need no cloud and the Plugs switch very fast.

The Script i wrote to Switch the when im not in the WiFi Powerplugs:

steckdose.sh

#!/bin/bash

ping -c1 IP_OF_THE_MOBILE > /dev/null

if [ $? -eq 0 ]

then

wget -O /dev/null http://IP_OF_THE_POWERLPLUG/cm?cmnd=Power1%20On

exit 0

else

wget -O /dev/null http://IP_OF_THE_POWERLPLUG/cm?cmnd=Power1%20Off

fi

i installed a cronjob for every minute that execute the script, and it works very well.

@foxy25 What do you switch on/off with the Gosund? The monitor?

Maybe you can get rid of the extra device. 2 Solutions in my opinion:

Use relays and control it via the pi4 directly - https://tutorials-raspberrypi.de/raspberry-pi-relais-schalter-steuern/
Try to use vcgencmd display_power 0 and vcgencmd display_power 1, i think this will work (or maybe echo 0 > /sys/class/backlight/rpi_backlight/bl_power)

There a various ways to turn off the RPI displays. See here:

Hi,

uhhh yes… sorry, how stupid from me…

I switch the display an and off with the WIFI-Powerplug.

There a many ways to fullfill somebodys needs. For me the Wifi-Plug and the small script was ein easy way to deploy that. The goal was to switch the Display complete powerless to save energie.
Not only switch the display to dark or switch of the HDMI-Port.
It works very good and im happy with that solution.

@foxy25 No, not stupid.
This was just a hint. Nothing more.
But thry a relay ;) then you can really make it powerless without the gosund.

Like you told us. Your friend is a carpenter. He uses a Festool! Very nice. And also how he cut out the piece including the corners.

If you have some rest of the yellow wall color in you cellar… dig in the platering, put in the cable from the outlet, put cement on it, sand it and paint it. No one sees the extra wire. Just a hint, its your house! I would have do it in that way. It think its worth the time.

Hi OberfragGer

Yes i know, but now it is set and good ;-)

In a couple of month i renovate my apartment including the kitchen, entrance hall and living room,
so i want to hide the wire. Maybe i set a new powerwallplug behind or above the cabinet.

But for me it is ok. Thank you for your hints.
