I’ve recently finished my sister’s magicmirror running a 27" monitor and pilkington mirropane chrome spy 4mm glass.
Adopted many great modules (thank you authors!), added my own modules as well as embedded custom voice commands and a custom wake word.
Run into m a n y issues during the whole process until it finally hang at the desired wall. (3 1/2 years :/ due to stacked schedules)
Funniest problem was that the mirror wasn’t able to recognise my sister’s voice, but had no problem with my deeper voice.

problems

• sdcard failure
  solution: replaced sd card, frequent sdcard image backups after bigger software changes, removed auto-restart every day and replaced it with auto-reload MM instead
• MMM-GoogleMapsTraffic crashing the software
  solution: auto-reload MM twice a day
• MMM-AssistantMk2 v2 having slow reaction time on first request (mirror start/reload)
  solution: added useWelcomeMessage: “hi” and simultaneously mute the sound output and put it back on after 60seconds
• voice of sister not being recognised
  solution: raised mic sensitivity and added custom wakeword with her voice
• performance and temperature
  solution: used a stretch and buster version simultaneously and let it run for a month - stretch version was slower, hotter and crashed 3 times
  buster was flawless and cooler / similar temperature (even without an active fan)

used modules

• weatherforecast by MichMich
• currentweather by MichMich
• mmm-systemtemperature by MichMich
• compliments by MichMich
• newsfeed by MichMich
• calendar by MichMich 3x (customized)
• MMM-pages by edward-shen

• custom modules:
  logo
  notification
  frame

MMM-Page has 3 pages configured - normal screen | fullscreen google maps | “guest screen”, hiding calendar, todo,… - module is controlled by MMM-AssistantMk2

currently running beside the MM software

• flask webserver
• openvpn for maintenance
• python script that searches for devices in her network (smartphone, notebook) to detect if someone’s home and therefore turns the display on - otherwise display is off
• the same script also restarts the mirror in case of getting 80 degrees and restarts the openvpn connection on failure

hardware

• Raspberry Pi 3b+
• Transcend Ultimate microSDHC 8GB Class 10 UHS-I
• kinobo mini akiro usb microphone
• 27" fullhd monitor AOC i2770PQ
• spy-mirror-glass Pilkington Mirropane Chrome Spy 4mm

enough issues, here’s the mirror and a live demonstration:

video was recorded with the stretch version and rpi3b
https://youtu.be/fZR0dvKM5q8

I am also running a “terminal” on my desk with an old netbook display and MM software and will soon finish my own mirror.

sure, might not be great, but it works well for me: https://gist.github.com/blaukon/1e6c4c9ad6ae98ad62545e1659555ecd

Might not work with every smartphone, for example, it works well with my Samsung Galaxy S8, but not without turning deepsleep off at my parents S7. Also did not work properly on my Sisters Huawei P20. Tried every setting but Android does turn Wifi off although “keep wifi alive even in standby” setting is active.
Just added my sisters Laptop IP and so far, it’s working fine at her place.

Added a picture of the mounted mirror: https://drive.google.com/open?id=1Qg0bFbfYzMh_SpuGu-rBGkeVRfeSMuOe

sure :-)
Uploaded my config.js and custum.css files (https://drive.google.com/open?id=16hNIqnGdpdmm9KeE-jcLGc0-fB80OpML)

You have to add your credit card to use googlemapstraffic, but you’ll have a free contingent per month which I never exceeded.
The ring my phone thingy is already implemented in the original google-assistant - as long as you use the same google account, you might have to grant the rights to use this function.

@hayman thanks! Please keep in mind that I’m not using the newest version of AssistantMK2. I’ve changed the following lines in his code (commented as “NEW”), this way, it will only me shown, if MMM-Hotword detected the hotword:

  prepareDom() {
    ....
    this.subdom.youtube = ytOutput
    this.subdom.wrapper = wrapper

    wrapper.style.display = "none"			//NEW
    return wrapper
  }

  activate(profile, textQuery=null, sender=null, id=null, sayMode=false) {
       ....
      if (this.config.onActivate) {
	this.subdom.wrapper.style.display = "block"	                   // NEW
        setTimeout(()=>{
          this.doCommand(this.config.onActivate, "onActivate", "onActivate")
        }, this.config.onActivate.timer)
      }
      ....
  }

  deactivate(cb=()=>{}) {
    this.changeStatus("STANDBY")
    this.subdom.wrapper.style.display = "none"			// NEW
    this.sendNotification(this.config.notifications.ASSISTANT_DEACTIVATED)
    this.quietRequest = false
    cb()
  }

@sdetweil

• sudo raspi-config
• Advanced Options
• Expand Filesystem
• reboot
  that might help :-)

@banbutcher yes, used screen and nethogs and tried lowering the refresh-rates of some modules and the data-usage dropped quickly

@justbob
It’s currently laying on my desk :-(
Couldn’t find a proper way to detect new mail properly yet.

@phmandl hey, what do you mean by config-file? I’ve already uploaded the config.js to my google-drive: https://drive.google.com/drive/folders/16hNIqnGdpdmm9KeE-jcLGc0-fB80OpML
or do you mean the modul-files?
I have not changed any mmm-remote settings or module-code.

@hayman thanks! Please keep in mind that I’m not using the newest version of AssistantMK2. I’ve changed the following lines in his code (commented as “NEW”), this way, it will only me shown, if MMM-Hotword detected the hotword:

@bachoo786
I had no trouble reading the texts neither at night or day - you can easily adjust the brightness via MMM-Remote:

@phmandl bought at glas-star.de “Pilkington Mirropane Chrome Spy 4mm (Spy4) 0.3” : 82,00 € + 70,00€ shipping (:/)

@bachoo786
hey, as far as I can remember, the glass is slightly bigger than the monitor and the frame is also slightly bigger than the glass, no tape was used, since you only see the monitor in the frame and not the “frame” of the 27" monitor.

tried to show it graphically with my old expanded notebookdisplay:

if your recoding is still quiet, even when you’ve raised the sensitivity, it’s mostlikly your microphone :/
I’ve bought this one https://www.amazon.de/Kinobo-Mini-Akiro-Mikrofon-Windows/dp/B00NSOWWIS
and also one that looked like 99% the same, was cheaper, but wayyy worse in comparison.
