Where can buy this mirror and how much did you pay?

Depends on where you live. I bought it from glas-star.de few years ago for about 160€.

@TGBB said in Frameless Bathroom Magic Mirror (Hue-controlled):

@stephanvdplas you not worried about condensation in the electricals?

Not really. I observed the inside with a humidity sensor for about a week and didn’t notice anything significant (believe me, i shower very hot) - but of course, time will tell. I secretly hope it will only last two or three years, since this was my 10±year-old main display and I would finally have a reason to buy a dedicated OLED display for it.

Nice side effect: the screen seems to have an anti-fog effect on the mirror glass.

Hi all!
After a long break with some woodwork excursion, I finally finished our main bathroom mirror.

The mirror is composed of:

• Pilkington MirroView 6mm
• Raspberry Pi 4B
• 24" Display BenQ GL2450
• Solid-State-Relais (SSR-40DA)

The frame is made of plywood and glued to a black foil, which is attached to the mirror glass.

I use a Hue Tap Dial Switch to control my YouTube module:

Some anecdotes

I’m really satisfied with the end result, despite encountering quite a few setbacks along the way. For example, I should have tested the backlighting more thoroughly before applying the glue onto the frame. I also wanted to make the backplate, which holds the display, removable. Unfortunately, it seems that i used too much glue in the final step, and some of it must have spilled over, unintentionally gluing the backplate as well.

Additionally I also didn’t think about the display’s standby message until I had already assembled the mirror. This resulted to some experiments with a mechanical relay and eventually a solid-state relay, which instantly cuts the display power without any delay or unnecessary notifications.

For the power management I initially planned to use a Doppler microwave sensor (RCWL-0516) as motion sensor. While it worked fine during development, it didn’t function at all behind the mirror glass. As a result, I got rid of it and started developing a module to integrate it with our light switch, which I modified using a Hue Wall Switch module (which itself was also not straightforward since the light switch was coupled with the bathroom ventilator, but that’s a different story…).

The probably more interesting part

I wanted to keep it simple and only planned to use ~50% of the display since the beginning. Because it’s our main bathroom mirror, i focused on what i really want to see in the morning.

• Default Clock module
• Default Calendar module (hidden)
• MMM-Pir (will propably replace it when it’s not working anymore)
• MMM-CalendarExt3Agenda
• MMM-OpenWeatherForecast
• MMM-DWD-WarnWeather
• MMM-Miku
• MMM-HueControl
• MMM-RemoteYoutube

The last three modules are written by myself, since i was too lazy to search for fitting existing modules or didn’t want to compromise.

Credits

While this project gave me quite a few short nights and several headaches, I had a lot of fun during the research and build. I’m really impressed with how far the main MM² project has come, and I truly appreciate it and everyone that contributed to it.

Special thanks to @spitzlbergerj , i took a lot of inspiration for the frame work from his work and of course all app developers of the modules from above.
