MMM-Loxone

idoodler

@bobbythemoh Let me quote the Readme.md for you.

This module doesn’t have its own visualisation, but it exposes information like the room temperature and other states other modules can and will use.

There is no UI, so it doesn’t make any sense to display it in the top right corner. Just uncomment position: "top_right", and MMM-Loxone won’t be displayed on your screen.

Motion sensor

Again, let me quote the Readme.md

If enabled this module will use the LightControllerV2 in the defined room to set the MagicMirror to sleep or wake it up

Requirements:

roomUuid must be defined in your config.json
The defined Room must contain at lease one LightControllerV2
presence must be defined and set to true in your config.json

How it works:
The HDMI port of the Raspbery Pi will be dissabled, whenever you switch off your lights. Your monitor should then dissable its backlight automatically if there is no HDMI signal after a specific time.

Right now there is no automatic power saving (after a specific time), I may add it later tho.

Example:

You enter the room -> Light switches on, mirror switcheson
You leaf the room -> Light switches off after the defined timeout, mirror switches off

Definition:
Lights off = The mood “All off”

Do I use the LightControllerV2"?
Well, you should, it is much more powerfull than its predecessor:)
Just open the App, open your LightController, click on the lower right “More” button and look out for the word “Moods” (“Stimmungen” in German).

But I am missing an importand Feature!
Please file a Issue and describe what you are missing, I may implement it;)

Thank you very much for the help, its really nice what you created with this module.

I skipped the GUI as you suggested, RoomID is set, LightcontrollerV2 is in use, Presence is TRUE.

What i changed on RPI config was :

/boot/config.txt

#hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=68
hdmi_blanking_1

I am using VGA Monitor with HDMI to VGA adapter.

Setting “presence” to true gives me a black screen after loading MM. Swtiching on the light in the room switches on the backlight of the monitor but does not show the content. The good thing is, with this configuration there is no power consumption of the lcd any more.

Using VNC i can see the magic mirror, so i think its a “screensaver” issue.

next thing i am trying is

sudo apt-get install xscreensaver

There was a hint that it is possible to disable the screensaver with this tool.

thanks for the help

bobbythemoh

OK it seems that it is not a screensaver issue. I fully disabled it and the content of the magic mirror is not coming back. its just the backlight of the LCD that is getting switched on and off. any Idea?

@bobbythemoh This sounds like you use some kind of other „screensaver“ which just displays a black screen instead of switching off the HDMI Port. I think you somehow enabled „screen blanking“.

@bobbythemoh btw. Just blacking out the screen is not realy saving much power if the backlight is still on… You just have to install MMM-Loxone, it will switch off the HDMI signal everytime the lights go out, your monitor will handle the rest (you might check your monitors Power saving setting).

@idoodler
Here is what i have observed:
XScreensaver is installed, Screensaver is disabled.
Rebooting the magic mirror with presence ON and light in the room on gives the magic mirror as it should be.
Leaving the magic mirror in this state (and also the light in the room) does not lead to screensaver, the picture stays as it is.
Switching off the light in the room also blacks out the monitor, power consumption goes down to 5W also without “#hdmi_blanking_1” but here is the issue:
Switching on the light in the room after blacked out monitor brings the monitor backlight and the power consumption back but not the UI.

With VNC i can see the UI, moving the mouse does not bring the UI back on the direct connected monitor.

Any idea?

@bobbythemoh I guess you have some sort of other “power saving” feature activated I am not familiar with. MMM-Loxone directly toggles the HDMI output on or off. It isn’t displaying a black view on top of the screen.

Please verify your /boot/config.txt!
In one ofyour posts you wrote hdmi_blanking_1 but it should be hdmi_blanking=1.

bobbythemoh

OK you were right, i changed it but there is no change in the behaviour. The Monitor remains without video signal just with backlight if i switch the light in the room on. Do you have any hint for me what i can check?

idoodler

@bobbythemoh Did you reboot after correcting the option?

@bobbythemoh You may also try to uninstall xscreensaver
