@sdetweil Thanks for the suggestion. You were right. It was a Home Assistant automation going haywire. The automation switched off the screen via MMM-remote-control. On top of that somehow the “blank screen” option in the Pi settings was turned on again (no clue why, maybe after the last update).
Anyhow I now tamed the automation and turned off the blank screen again and now it seems to be working normally again
Wow, I am blown away by the many responses. Thanks so much guys!
Especially thanks @sdetweil, for pointing me in the right direction with MMM-Remote-Control. That module is absolutely awesome. I now figured out the whole thing, so here it is if anyone likes to know:
First I installed https://github.com/Jopyth/MMM-Remote-Control
You need to use the Rest API requests as in the instructions in the module
I found this for HA: https://community.home-assistant.io/t/controlling-magicmirror2-from-ha/138527
So I need to add each rest api call I want to automate as service in HA. Then I can trigger the service i.e. shutdown in my “leave house” and “night mode” automations.
There are then 2 steps:
When the state change is triggered (e.g. I return home or I start moving in the house in the morning) then the automation just turns the outlet back on and the Pi will boot.
@hesspoint Update: There is actually a custom HA integration that is awesome: https://github.com/sindrebroch/ha-magicmirror
So I switched form the REST API to that integration and it is even better
Hi everyone,
sometimes when my MM screen comes back on (I have an automation that turns off the screen and turns it on via motion detector) the image is completely sideways and distorted / wrong resolution
Normally the image is of course upright and higher rez.
In fact it seems to be more Pi itself related than purely MM as when I restart the MM and it briefly shows the Pi Desktop it is also sideways and low rez.
It is not always but I am having it roughly once per day. Only thing is reboot of the Pi.
Did anyone encounter something like that and were you able to fix it?
Thanks!

Hi,
I have my Magic Mirror running since a few days.
It was all working well until now. What I did was that when I am not in the room, I would cut the power to the display and when I enter the room, the outlet where the screen is plugged into turns on and the screen comes on (via motion detector and Home Assistant). The Pi stays on, just the screen shuts off.
That was working flawlessly until today.
Now I have a problem. When I boot the Pi and the screen is on it will connect to HDMI1 and MM will appear. But now when the display is shut off and comes back on, the little light for the display is red and there is a onscreen message from the display “no signal” I tried to go into the OSD menu of the display with the control buttons to try to switch the input source but but it won’t show the OSD menu.
The Pi is definitely running as I can connect via SSH and also via MMM-remote-control.
However when I reboot the Pi then it connects via HDMI and show the Pi and the MM just fine until the display is powered down again and then it stops working again.
hdmi_force_hotplug=1 is set and as said it used to work just fine until now. I did install a few modules to MM but since it also does not show the Pi’s Desktop or anything at all, I don’t think it is related to MM itself.
Any ideas?

Hi everyone,
I finally finished my build and the mirror is on the wall :) I can share my build sometime if you are interested.
But I have one point I need help with: I want to shutdown the Raspberry Pi at night and when I am not home (energy consumption, safety etc.) and I want to automate this when my house changes it status e.g. from ‘home’ to ‘away’ > shutdown and when i get back then powers up again.
I run my apartment on Home Assistant (running on a different Pi than my mirror) and I have built a Koogeek smart powerstrip into the mirror to which the screen and the Pi are plugged in. I can switch each outlet on and off via HA, which I do with the screen right now, which turns off 5 min after the motion sensor stops detecting movement.
I could do the same with the Pi easily but my fear is that if I regularly just kill the power on the Pi without proper shutdown, that it could mess up something on the memory card or kill the Pi eventually.
Or is this unfounded and it is perfectly ok to just pull the power? As this would be the most easy solution.
If killing power is a bad idea, do you have any ideas how to realize this with Home Assistant? Maybe via MQTT or so? I have already done a ton of research if there is a way to control another Pi via HA but nothing useful turned up (no integrations, add-ins, not even in HACS or somewhere on GitHub).
So if anyone has some insights here then I would really appreciate it!
Hey @Messel
I have used your built as inspiration, and it is basically done. However there is one problem that is plaguing me and I don’t know how to solve it and that is light bleeding in the corners.
I saw in your pictures that you partly have the same issues however it seems not as bad as for me. Did you do anything to get rid of this cross like optics?
I tried a lot from closing the corners with duct tape to little wooden blockers in the frame etc. but nothing seems to work really.
For a bit more context, there are lightstrips facing the wall. Most of it is under opaque cove. Also you can see my experiments blocking some of the corners with tape
