MMM-PIR-Sensor-Lite modification
-
@Freddy_boy you could copy it out of the ext screen module which worked… (if u still have the older repo installed somewhere)
thats what I did when I was testing PIR and other sensors a year or so ago
-
I attempted to run the CEC commands manually, but that doesn’t work. I just keep getting active source unknown error message. Unfortunately, I don’t have the original EXT-Screen module because I attempted to perform an update on the module, so I only have the updated module. Perhaps the updated module has updated code? But I don’t know where to look for the required commands. I’ve looked at the EXT-Screen.js file and the node_helper.js file and I don’t see anything that looks like a CEC command. Also, the files are difficult to view, as the entire code is written on a single line, so you need to search for text strings to find anything.

yes, he has minified the code to prevent others using it… or learning form it…
does this work to list the cec devices?
echo 'scan' | cec-client -s -d 1 -

Update: I’m not sure how it happened, but I believe that my monitor had the controls disabled. It is an LG monitor using Simplink, and when I enable it, I can now see the device:
pi@raspberrypi:~ $ echo ‘scan’ | cec-client -s -d 1

However, when I attempt to turn OFF the monitor using the CEC control commands, it doesn’t seem to work. The commands appear to be working (ie. no error messages returned), but the monitor remains ON when I issue the standby command. I also use the ‘power’ command to check the status of the monitor, and it confirms that it is ON.
pi@raspberrypi:~ $ echo ‘pow 0.0.0.0’ | cec-client -s -d 1

I have also tried:
sudo echo ‘standby 0.0.0.0’ | sudo cec-client -s -d 1but got the same result…
-
@Freddy_boy ok, I have a CEC tv which I can turn OFF, but not back on…
-
Yes, but this used to work previously. I suspect that none of the commands are working (even if no error message is returned). I attempted other commands, and they also do not seem to work. For example, I tried to change HDMI inputs, and the monitor remains at the same input. I think I need to determine if I can get ANY HDMI CEC command to work at all. It seems to be a missing step somewhere…
-
@Freddy_boy I have not studied the CEC commands

@Freddy_boy google is your friend… sort of…lol… i would search the messages…

As I dig more into this, I am finding that there seem to be a lot of reports that some LG monitors do not support using the Standby command. I am not certain of how this was working before, but now I am beginning to suspect that the Magic Mirror app simply went hidden when the timeout occurred. Perhaps the monitor was ON all along, but the app disappeared from the screen? I don’t know if this applies in my situation, because I can’t seem to make any of the CEC commands work at all.
I attempted to turn OFF the monitor, and then issue the CEC ON command, but that also did not work. It appears to be some fundamental issue with the CEC commands that I may not be able to use. Are you aware of any modules that simply blackout the Magic Mirror app using the PIR sensor? I know that isn’t really saving as much energy, but it might be worthwhile implementing…
-
@Freddy_boy you can try my MMM-SleepWake
https://github.com/sdetweil/MMM-SleepWakeit listens for pir sensor or lite to signal user presence
and mode HIDE will hide all the modules and show them again when a user appears
I built this to use this with a webcam as I don’t have any pirs, and none of my monitors will behave (big ‘no power’ warning when hdmi goes off)
I just added the code for sensor-lite, just a check …
-
I assume that I would need to re-configure the MMM-PIR-Sensor-Lite module to prevent the command from turning OFF the HDMI. How do I do that?
-
@Freddy_boy dang, this module also doesn’t alert other modules…
too much to change quickly… sorry
-
Really…
Should I recode a module by merging screen and pir plugins ??
Yes, I can do it but… I not really interested to maintened it
@sdetweil: if I add you to contributor, you are able to “maintened” it ?I will create MMM-Pir

@Freddy_boy
Hi, my MMM-Screen-Powersave-Notification module can do this job. It has ahideInsteadShutoffoption.
You need my MMM-GPIO-Notifications in addition.
I wrote a Guide of how to configure the modules. -
@bugsounet said in MMM-PIR-Sensor-Lite modification:
I will create MMM-Pir
It’s done.
It’s based with myEXT-ScreenandEXT-Pirplugins
I have rewrite and clean it for MMM using@wishmaster270:
do you want to try to maintened it ?
I can add you as contributor
(I see that you forkEXT-Screen)
I have really no time for any MMM :/ -
@bugsounet Hi,
sorry but at the moment a do not have plans to maintain more modules than i already do.
In addition i do not see a reason why there should be a need for a additional screensave module.
Most of the features are present in the exiting ones. I do not like the idea of putting the GPIO logic and screensave logic into the same module and had problems with it in my setup in the past. Thats why i created the two separted modules.
I forked MMM-Screen as i wanted to check if there is a easy way to implement the CEC logic to my screensave module. I do not think it would be a big deal. The problem is that i do not have a CEC aware monitor at the moment and do not have the time to build a dev environment with my tv. -
Terrific! I just installed MMM-Pir and it works properly as before. I am using mode 4 (HDMI CEC) and the monitor responds as expected. Thanks very much for the quick response! You guys are a real credit to this open source project!
