My Smart Home – Chapter 1: The Mirror

A colleague complained that he has a 22-inch screen which he doesn’t use anymore but he can’t sell it for a valuable price. So I said he can give me the screen for free and I would convert it to something cool, I had already an idea what I want to do with it …

My intention was to display some measurement data of my home which I collect with Netatmo or WirelessTag . Furthermore, I had the idea to supersede the paper wall calendar with a digital calendar. We use already Google calendar but my wife has the opinion that she need a calendar not only accessible with a computer or a mobile phone, there must be also something on the wall to get faster an overview about the upcoming events.

Mirror, Mirror, on the Wall …

So I told my wife that I plan to install a monitor screen in our entrance area, honestly the enthusiasm was very limited. I found out that the WAF – the wife acceptance factor for a monitor screen in the apartment is pretty low. So I needed another idea, accidentally I saw the  MagicMirror² Project which is the solution for my Software Plattform and also the word “Mirror” solves the WAF-Problem.

So there is now no more a monitor screen, instead my project is a Mirror, a Smart Mirror to be precise. Behind the Mirror is a Raspberry Pi 2 located which is powered on 24/7, rather the power of the screen itself is controlled by a MyStrom Wifi Switch  in early morning a motion dedector turn the mirror on, at other hours in the day the screen can be activated with a push on a MyStrom Wifi Button. If the Mirror is powerless it looks like an ordinary mirror.

At the end this was how my prototype looks like:

It was a long journey and I invested a lot of hours until I was happy with the result of my project.

First I started to cover the screen with an acrylic glass laminated with a mirror foil. I was not satisfied with the result, I had inclusions of dust and air under the foil. Only the more expensive but high-grade real Spy-Glass from myspiegel.de made me happy.

It was also difficult to decide which content should appear on the display.

Content

Currenlty my configuration shows ths content:

Top left
– Date and Time
– Google calendar from my an my wife

Top right
– Weather forecast
– Hue Status
– Recent Calls (Fritzbox)

Bottom left
– Trello Task of our family

Bottom right
– Power meter of different Powerplugs (REST via MyStrom)
– battery state of charge of my EV

Bottom center
– Headlines of “Berner Zeitung” the local Newspapar (RSS)

Component List

  • 22″ Screen who has a Digital Input – Raspberry has only HDMI (I took an old one and removed the Case – on your own risk!)
  • Raspberry Pi & Power Supply
  • Spy Glass – I ordered on myspiegel.de
  • Smart Plug (optional)- e.g. I have this one MyStrom Wifi Switch 
  • Smart (IoT) Button (optional) – e.g. I have this one MyStrom Wifi Button.
  • Motion Sensor – e.g I have one from WirelessTag  (optional)
  • Some pieces of wood from your local DYO Store

(As Tools I used a hot glue gun, a saw and some screwdriver )

Conclusion

The mirror definitely gives an added value, but it’s really only for DYO’er or Nerds … No Enduser-Friendly product. It also needs maintenance.
This is a device for consume information but you cannot interact with your devices. Maybe in Some years possible with a “Touchscreen-Mirror”.

+ Added value in a Smart Home
+ Cheap
+ – Open Source (Open to integrate other things, improve code vs Security)
– Not an End-user product
– Needs Maintenance
– Only shows information, no interaction with devices

  • Wow looking fabulous your Smart Home

  • hi, this is very useful information for the smart home who construction newly. thank you, sir.

  • Hallo,
    toller Beitrag!
    Ich möchte für eine Präsentation das Smartmirror-Prinzip nuten und anstatt Nachrichten, Wetter etc. ein Video abspielen lassen. Nun ist allerdings die Frage ob auch alle Farben gut wiedergegeben werden, oder ob man eher nur schwarze Schrift gut sieht.
    Also dass das Prinzip eher für Schrift ausgelegt ist und nicht für Bewegtbild?

    Vielen Dank euch und beste Grüße!

    • Hallo, ich habe das auf meinem SmartMirror nicht getestet, ich war aber schon in Hotel’s welche Tv’s im Bad hinter dem Spiegel hatten und somit eignetlich das gleiche Prinzip nutzen. Natürlich ist die Farbe nicht ganz so echt wie ohne Spiegel. Aber es funktioniert. Viel Spass beim basteln.
