@timjong93 spawn background process, good… that is how voice works and a bunch of other things that have defined processes…

and I recently saw MMM-RemoteControl, which seems to support sending command strings …

that only works for PI devices where tvservice command exists… I run MM on an ODROID so, that doesn’t help…

I also use an EnergyStar TV, which freaks out when the video input signal is cut and then powers off after 15 minutes…

i think you are on the right path…

the module.js can see other modules for show/hide, but the node_helper cannot
the node_helper can import other libraries, where the module.js cannot…

i just made MMM-SleepWake (https://github.com/sdetweil/MMM-SleepWake) which allows some external source (camera via https://motion-project.github.io/) to indicate motion or not, (by writing a file),
and the node helper uses the file system support to detect that file… and then decides what to do…

• if it can directly control the display device (pi, or use DPMS), then the node helper does the work. but my system runs on an ODROID SMC, so the pi tvservice command doesn’t work to turn off the monitor (my TV)…
• the DPMS command (seen used by HelloLucy) turns off the hdmi/dvi source…
  on my TV this shows the big blue ‘NO Input’ screen (counter to what I wanted!)…
• so I have a software driven sleep (that hides all modules, and remembers ones already hidden)… but that has to be implemented in the module.js… so there is communication from the node_helper to the module.

whether its file, or sockets, or some queue… you’ve got the right idea…
I use HelloLucy (on top of MMM-voice) to sleep/wake and hide/show modules via voice.
i don’t see any ability to inject phrases to the processed in that module…

@tnp0327 minimize the mirror window (alt-spacebar, n) and the terminal windows used to start the mirror will be shown… the debug is in that window…

least thats how I do it!..

this debugs the node_helper
ctrl-shift-i will open the mirror debug window (select console tab) this will show the module level debug

i think both frequently used apis (darksky and weatherunderground) have both gone to pay for use models…

I am not aware of another free api

if you got an api key before IBM closed free access, the api key still works (for how long I don’t know)… mine still does

Description

Enable MagicMirror sleep from external (camera) sources

If you are running the MM on a non PI device, or want to control sleep/wake without having to wire up another device, this module will take external info and signal MM to sleep or wake up.

I use a Webcam camera for the motion detection, driven by the github Motion project.
That project allows for a script to be run when motion starts and ends. I provide a script that
creates a file for both events, and the module detects those files.

the module supports sleep and wake 3 different ways… On PI using the tvservice command, or the exec dpms command if not using HDMI, or hiding all modules if using an energystar monitor (like my tv)

I have submitted changes to MMM-voice and HelloLucy to allow our modules to know about the others processing… so voice Go To Sleep and motion wakeup work… if using the Hide method, modules already hidden at sleep will remain hidden on wakeup.

Version 1.0

@teitlebot you didn’t post the script

this fix is now added to the develop branch, and will be merged to master at some time.
Thanks Mitch
