First things first. It all started 2 years ago when I started building a smart home system based on Home Assistant. The next logical step for me was a smart bathroom mirror that would display my calendar, commute to work information, weather info and sensor info from my smart home.

I had all the needed hardware - 24"LCD, Raspberry Pi 3b+ and etc.

I wanted a frameless mirror as it looked more slick, modern and professional.

I decided to go with the mirror that Goldjunge_Chriz offered as it had a lot of positive reviews on the forum albeit being more expensive.

The setup is the following:

• 80x73 cm two-way mirror (I was the unlucky winner who got a broken mirror by the courier, but that’s another story. I managed to glue it just for the sake of testing. I found a mirror company here in Bulgaria that offers a better and cheaper alternative but I will share more details on that later)
• 24" LCD monitor
• WRGB LED strip behind the mirror, controlled by H801 Wi-Fi controller integrated with Home Assistant
• PS3 eye camera behind the mirror which is responsible for face recognition and voice commands
• External motion sensor turns on the mirror and switches it off after there is no motion detected (Home Assistant automation)
• The WRGB LED is controlled by Home Assistant

The frame:

• Built out of 50x50 mm Г-shaped aluminum profiles, welded together
• On the back of the mirror there is a non-transparent foil cut to the dimensions of the monitor
• The frame is glued to the mirror through the foil

Some pictures of the back of the mirror before it is installed:

Considerations:

• The mirror is too dark … it is not suitable for rooms with no natural light. I will be testing another mirror at a later stage and will come back with the results, but this one is definitely not going to serve as a normal mirror in your bathroom.
• You have to stick something to the back of the mirror (e.g. non-transperant foil, wood panel or something else, otherwise you will be able to see through)
• If you can afford it (I can’t at the moment) go for an OLED monitor/TV - the LCD backlight is seen through the mirror and while it is not that bad I am perfectionist and it bothers me :D

@ChrizZz I followed the tutorial and installed OpenCV and all dependencies in a virtual environment, but that did not go very well afterwards, you have to reconfigure the module with the correct paths and that can be cumbersome, therefore I started on a clean state and installed OpenCV and the dependencies without a virtual envioronment - e.g. follow the same tutorial without the part related to virtual enviornment. That is the most appropriate for our use case.

@ChrizZz I have used camera motion detection and I gave it up, because:

1. It is not very reliable (maybe it was just my cheap camera that I used for testing back then)
2. it is resource hungry

Because of that I use an external wireless PIR sensor which is part of my smart home system to turn on/off my SmartMirror and it works great. Since the motion processing happens on my smart home system and the Mirror is turned on/off via SSH command it takes up no resources at all from the MagicMirror which is already at 60% load when using Facial Recognition.

@bkost I am using three different PSUs - A 5V 3A for the RPi, a separate 5V 30W for the LED strip and the original PSU for the display, but it all depends on your setup and the length of the LED strip. However, I would advise you to have separate PSUs as the LED strip draws quite a lot of current especially if all channels, including the white are used.

C’mon guys, we need 8 more people :)

After few days of installing (it takes a lot of time to build OpenCV 4.1 and dlib), trial and errors I finally installed and configured the module and oh boy is it good? Yes it is. It is much faster and accurate than Facial_Recognition_OCV3 that I used before. It was tottaly worth the time.

Thanks a lot to nischi for responding so quickly to the issues I posted on GitHub and to the enhansments he made based on my feedback.

Yeayyy, we need one more order :) C’mon guys!

@snille in the config.js:

Has anyone received their mirror? Mine arrived today but it is broken :(

I finally found out what the issue is. It was an electron bug that is fixed in MM v. 2.18 (I was using an older version). Now everything works.
