@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.

Hello!
My second mirror is almost finished and ready to be published :-)

Functionality

• Google Assistant

  • Turns on PC+3d pinter

Mailbox - Remote connection (ryrl896) - if my physical mailbox lid is triggered, it will send a character (mail) to the mirror (5 floors above), opening the mailbox will sends(clear) + it sends once per day “alive” (still work in progress)

• cam_street (own module: shows stream of balcony)
• cam_door (own module: shows stream of frontdoor)
• mailbox (own module: shows status & time of new mail in my physical mailbox)
• MMM-PilightTemp (own module: shows temperature of my rooms 433mhz temperature sensors connected to a different rpi)
• frame (own module: shows frame for “who is the fairest in the land” made for my sisters monitor: https://forum.magicmirror.builders/topic/12307/magicmirror-project-for-sister)
• logo (own module: shows company logo)

Voice commands

• where is my phone
• who’s the fairest in the land?
• display logo
• display security
• front door / off
• camera on / off (Funksteckdose)
• street on / off
• refresh yourself
• printer on / off
• turn light on / off
• open relay (activates relay controlled by selfmade home-alarm, open house-door)
• turn pc on (WOL)
• amazon on (fireTV stick attached to TV)
• tv on / off
• switch soundbar on / off
• go to sleep
• wake up
• reboot yourself
• shutdown yourself
• mirror off (monitor off)
• ignore (mutes sound)
• mute yourself (mutes sound)
• shut up (mutes sound)
• resume listening (volume 95%)
• protocol one (TV on - via fireTV stick & PC on - via WOL)
• protocol two (3d printer on - via remote sockets & PC on - via WOL)
• show page 1
• show page 2
• show first page
• show next page
• show previous page
• show last page

scripts running in background

• lightsensor which adjusts the monitors brightness
• motionsensor, turns monitor on
• welcome message after being long gone (Welcome home name, it is currenty time)

unsolved issues

• monitor is still visible when it gets darker, although the brightnesssensor-dimming solution made it way better
• microphone isn’t the best - is there an ‘alexa, google home’ like quality solution? (Tried a 4-way mic-array, kinda had worse experience)
• voice commands only work in a silent environment

todo

• update to newer version and install the newer voice related modules
• find out why/what causes about 500mb traffic per day

Mailbox (unfinished)

• Sender - RYLR896+Arduino Nano
  => motionsensor for new mail
  => reedsensor for picking up mail
  => energy: “simple” usb powerbank with rechargeable AA batteries (does not shut off due to low power consumption)

• Receiver - RYLR986+ESP8266
  => energy via USB Port rasberry pi

@sdetweil

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

@stro voice responses are downloaded from google translate :-)

@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:

  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()
  }

@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.
