@maros Normally on a commercial mirror you have glass-silver layer-paint layer
I’m talking about removing only the paint layer without touching the silver layer

Anybody tried to make a two way mirror by just removing the paint layer from a standard mirror? If you leave the silver layer it’s supposed to give the same effect as a two way mirror but I’d like to know if the see through effect is good enough for a magic mirror

I got it working with your solution in the troubleshooting section!!! thx

@sean here is my complete log

thank you for your help :)

this is when I load my mirror with just hotword and assistant installed. I’ll try to rebuild electron again to get the log

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
Launching application.
pi@raspberrypi:~/MagicMirror $ 

Hello! I got Hotword working but assistant triggers error. I tried to rebuild electron as explained in the installation guide but it’s not working. I have the google voice kit installed on my raspberry… do you think that is the problem?

Is there a way to add bullets before each task?

I reinstall with the restore mode at startup and I reinstall all my mirror from scratch

I reinstalled raspbian and now everything works
