@Mirrorolentia If you can’t get that one to work or want to try a different one checkout AlexaPi. It’s a python implementation of Alexa made for all sorts of platforms.
You can get it from here: https://github.com/alexa-pi/AlexaPi

You can also use this mirror module to give status feedback on the mirror: https://github.com/dgonano/MMM-AlexaPi

Just be sure to pick the magicmirror platform during setup instead of the default raspberrypi
