  While trying to debug modules, I’ve been given quite mixed feedback regarding what to use to print messages to console, on either local system or in remote browser DevTools. So far, I have found the only reliable way that always seem to print something in the browser, is using console.error(). The others have varied. I’m on MM v2.2.2 (master).

  @blebbens Does the problem still exist? I just tried with the lastest version of MM & the module (which I’m also the developer of) and also configured your PWS and it worked just fine on my mirror. If it does not work, could you please open the MM on your web browser and report the JavaScript error message you get there (e.g. follow https://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors#Step_3:_Diagnosis to find the error message)?

  Unsolved Mirror freezes after a few hours

  Dear all, I am running the current MM-Docker image and have a Pi behind my mirror which runs in node clientonlymode (Rasbian Stretch). Both are running 24/7 while the power for the MagicMirror display is switched on and off with the light. After a while, the mirror freezes (e.g. clock will not update). The Pi is accessible via SSH and pm2 shows me that mm is online and uses 0% of the CPU. The MM-Docker Website remains accessible and up-to-date when accessed directly. What I know so far: Restarting pm2 restart mm on the Pi does not solve the problem. sudo reboot now does not reboot the Pi and the frozen screen remains visible. A hard reboot via the power plug solves it for a few hours. Do you have any idea, how to troubleshoot this? I don’t know where to start… Thanks a lot for your help!

  Hi there, i took my 1-year-old MagicMirror and switched from a Raspberry Pi 3B to a 3B+. I flashed the newest Raspbian Stretch to my SD card and installed MagicMirror 2.41 without any problems. After installing a couple of modules, I added a python script to crontab for fan controlling in cases of a system temperature over 58 degrees. I set up the PIR-sensor for switching on/off the monitor behind the mirror using MMM-Display-Controller - it is not a module. All this hardware and software was working in my old MagicMirror-Setup. The difference from the old to the new MagicMirror is the MagicMirror Version 2.41, Raspberry 3B+ and the fan python script. The new setup was working fine, too, including the PIR-sensor. But, after running fine for 1-2 boot sequences, it all comes to the same: the system boots up into MagicMirror and shows all the working modules. If no one is in front of the mirror, the monitor switches off. If the motion sensor detects a person, a blank screen is coming up, without any modules or, the monitor shows half of the modules at various places or, the monitor shows all the working modules, but the screen freezes (clock is not counting time etc) Sometimes, the system is answering via SSH - sometimes, it answers after a couple of minutes. I am very dissapointed - put a lot of work into this mirror… Could someone help ? Why is the new installed system freezing or showing a blank screen after all was working fine ? Are there any known problems with the Raspberry Pi 3B+ ? Is there a log I can post ? Thanks in advance…

  Hi all, yesterday i did an upgrade to my mm-pi (sudo apt-get upgrade) Unfortunately during the installation my son switched off the power supply. Now the pi starts but do not display anything (i think the mm hangs somewhere…) Connecting a keyboard and a mouse bring not any benefit. I am not unhappy about seeting up the system new…but the config file i want to restore. Is there a possibility to get this config file restored… I am not an expert I was not able to see the mm folder while searching throught the sd card on an windows pc. Thanks a lot for any help Regards

  @slametps said in MMM-NetworkScanner help needed: @Mykle1 try to execute the following in shell: arp-scan -l -q Compare all the scanned MAC with your MAC device entries in MMM-NetworkScanner. I have run the command sudo arp-scan -l -q and somehow find only devices that are in the LAN, but no device what is in the WIFI - so unfortunately no mobile. My MM always shows me only “NO DEVICE ONLINE”. I proceeded as follows: cd ~ / sudo apt-get install arp-scan cd ~ / MagicMirror / modules git clone https://github.com/ianperrin/MMM-NetworkScanner.git cd ~ / MagicMirror / modules / MMM-NetworkScanner npm install cd ~ / MagicMirror / config nano config.js { module: "MMM-NetworkScanner", position: "bottom_right", config: { device: [ { macAddress: "XX:XX:XX:XX:XX:XX", name: "I", icon: "mobile"}, ], showUnknown: true, } },

  Just to close the topic. I can’t connect with Internet Explorer. But I can with Chrome. Don’t know why, but I am a step closer to my goal. Hope it can help other magic Mirror builders.

  @stickyrib with the 2.4 release a heating problem arose with heavy cpu usage due to electron. Is was adviced tot use the fkms (see post michael). When i followed up on this post both alternatives did not work out for me. One option got me star night like flickering in the widgets on screen, the other led to what you described. So I returned to the driver which was used up unto 2.3. Never thought about powering via the monitor to be the probleproblem/solution, but I do connect it that way. So still on default screen driver and no heating problem and no flickering.

  Hi there. So I am currently working on a magic mirror to have in my home. We are visited by my girlfriends parents every year who are Chinese. Since they only speak Chinese I would like to assist them with a mirror they can look in to see the weather, public transport etc. The only issue I am having is to change the language on the mirror on the fly. I want to set in facial recognition, so that when one of the parents stand in front of it it shows Chinese translation, but for the rest it is English. Is this possible to do smoothly without restarting the whole mirror?

  Hi there, after months of not using my MagicMirror, I wanted to modify some components. I changed the Raspberry Pi 3 to a 3B+ and put the SD card into the newer one. Now, nothing is working like before… Raspbian is working very slow… most of the time the OS hangs for 2-3 minutes before executing my orders. I updated Raspbian using sudo apt-get update && sudo apt-get upgrade -y and pushed MagicMirrorOS to 2.41 using git pull & npm install. Then I switched to the GL driver via raspi-config. MagicMirror shows the screen like in good old times, but the modules are not updating after their initial screen. System temperature, for example, is showing 49 degrees all the time. Installed a PIR-script for my PIR-sensor, which was working fine in the past. Now, after 10 seconds, it is showing the screen for 5 seconds and switches it off again. The hole system is slow like hell… At the moment I am very dissapointed… tried to get it running several times using a SD backup… Is there anything I have to think about after switching the Raspberry Pi to a newer version ?

  So i’ve been trying to get MMM-AssistantMk2 to work but i can’t do it, the program keeps asking for a file that doesn’t exist. I’ve tried to do an electron rebuild but that doens’t help. I ran MM with npm start dev, and got this error WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module ‘/home/pi/MagicMirror/modules/MMM-Hotword/node_modules/snowboy/lib/node/binding/Release/electron-v2.0-linux-arm/snowboy.node’ In the directory there is a node-v59-linux-arm and node-v48-darwin-x64 but no such file as electron-v2.0-linux-arm
