MM current version on Raspberry Pi 5 cannot turn off monitor
-
@jbat66 yeh, probably the monitor they use behind the glass doesn’t support CEC
-
@jbat66 said in MM current version on Raspberry Pi 5 cannot turn off monitor:
I guess that is the default no input screen. lol
just unlug the hdmi cable, then u should see the default no input screen
-
@jbat66 Oh, Wait, I just realized - I switched bookworm into X11 mode rather than Wayland - you may need to do that as well (I couldn’t get some operations I wanted to do to work in Wayland, yet - setting in raspi-config/advanced if you’re using RasOS)
If you don’t mind the monitor running but just want a blank screen, turn off the background picture, set the color to black, and remove the taskbar, then turn off MM and let it be. Might still get a mouse cursor, but there’s tools for that (Unclutter?)
-
@BKeyport Thanks, I’m already turning off my background pictures, and just dimming (could also just hide all) modules. The problem is that I want to turn off the screen but leave the pi running, because one of my MM will be in an RV and when boondocking (running on batteries) you want to use as little power as you can, so it is silly to run the screen at night.
I am using wayland, didn’t know I could goto X11, and not have a problem with MM. I may look into that, thanks!!
As a side note I couldn’t get unclutter to remove the mouse in wayland as it does in X, but I found ydotool using this command works well in wayland to move the mouse to the bottom right corner, so it only shows one pixel. :-)
ydotool mousemove -x 5000 -y 5000right now, I have installed physical buttons, so I can shut the screen and pi down manually. I may crontab a shutdown of the pi, and then use yo-link (home automation switch) to kill the power after the crontab shutdown is done.
-
@jbat66 the mouse pointer should not show on the mm screen by default.
the main.css sets cursor to display:none;
-
@sdetweil Should is the key word. Some bug somewhere is causing the system to come up background to various things - sometimes mouse is on screen, sometimes the pi menubar is in front of the window (rare, but does happen). I had to use unclutter to fix one, and hide the menubar to fix the other. I know it’s not us, so it’s not reported to MM github issue.
-
@jbat66 not sure how much power the pi+power supply takes and if it would be worth it to shut it down overnight. Could rig a button to do a graceful shutdown, then use the power down button to shut down both the pi and the monitor. Interesting ideas here. Let me know what you come up with.

@BKeyport i have been transitioning to Home Assistant for my home austomation platform.
and interesting idea being described for integrating older devices, like washing machine, is to monitor the power consumption with a smart plug… (I don’t know which do that in the US)
I wonder if the ps also has a lower consumption that can be measured and used as a trigger to turn off the smart switch when the power drops after pi shuts down…
i’ll have to try to find one of these outlets
maybe

@sdetweil Get a Yo-Link Plug. They have an API, you get your API key from an advanced menu in their app. Their plugs do grab usage, I have not used the API to grab usage, just to turn on and off, and to get temperatures from their sensors. I then use the API in MM to display the temperatures.

The whole Yo-Link echo system is great for DIY folks in home automation. -
@jbat66 trying to find devices without host connections… get more/all local
-
@BKeyport the physical Mirror’s Power supply is the only thing I plug in, and the PI gets its power from USB from the display, so no extra power source to monitor.
I will probably just do a bash script to shut down the pi at some time say 10:00pm, then I will have Alexa shut down the mirror’s power (thus the pi as well) via a Yo-Link smart plug at 10:05pm. Then at sunrise via Amazon Alexa, I will just turn on mirror.
I already do this for my RV Starlink, since I have cell modem as a backup, I can use the internet to turn on and off my internet. lol

While the Yo-Link is great it is cloud and you can’t do local yet. They have been talking about it in their forums, however.

@sdetweil
I looked it up and you can get power readings via the API.

@jbat66 yeh gotta get a token for each I think

thats exactly what I plan for my washing machine

I ordered a smart plug from TuYa for this and tested this now with a raspberry pi 4.
When the pi is running:
After shutdown of the pi but red light of pi still on:
-
@karsten13 awesome. I hope my plug will be here today
-
@sdetweil So I ened up using a Yo-Link Plug, and it’s API. I have my monitor plugged into the Yo-Link Plug. I wrote a script that sets a delay time off to 1 minute for the monitor, and then 10 seconds later does a sudo power off command. So the pi shuts down gracefuly and then the monitor. The pi is powered from the usb connector on the monitor.

@jbat66 - thanks for the offer. If you do wind up sharing your work, I will take a look and see if it works for me.
I don’t run any remote control module, and don’t find the “MMM-remote” you reference when I search. I do, however, find at least two (2) different modules called “MMM-Remote-Control” by two different authors. Do you mean one of those?
My progress so far is that I can get the monitor to turn off using the following script (called by a cron job), but the monitor then turns back on after ~10-15 seconds:
#!/bin/bash # Script to turn off monitor display when called by crontab export WAYLAND_DISPLAY=wayland-1 export XDG_RUNTIME_DIR=/run/user/1000 /usr/bin/wlr-randr --output HDMI-A-1 --off -
@JohnGalt Can you add vc4.force_hotplug=1 to cmdline.txt (on existing line) and check if behaviour changes? Add a space at the end of the line, save and reboot.
Assuming you are using the first hdmi port closer to the usb c. If using the 2nd port then change the hot plug number to 2

Sorry I should have been more clear.
