@Sean Will you are again the man to ask about my last predicament!!
It is regarding MMM-Hotword … i have AlexaPi installed independently of Magic Mirror on the same Rpi and i want to install MMM-Voice as well but they are conflicting over microphone resources how can i use them both with either 1 ore 2 USB mics ( i have 2 mics if it’s easier) but don’t know how to configure them to be used by the 2 programs - 1 each. Will MMM-Hotword be able to achieve that i want to do use Alexa and Voice module on the same mirror.
Again please point me to the right direction.

First, I haven’t been using AlexaPi and MMM-Voice.
With short glance, It seems different mic could be assigned to AlexaPi and MMM-Voice separately.
(See the AlexaPi and MMM-Voice Configuration.)
But I don’t know whether it would work or not.
And I’m not sure MMM-Hotword would do that. Because AlexaPi is out of MM. So, It is not controllable by MM. You should use another mic or even another RPI.
I think, The better way of voice controlling with Alexa is to use Alexa Skill, - like MirrorMirrorOnTheWall

ah great thought I already seen I alexa module that receives the messages. I guess thats a lot better (and easier) solution than running two voice recognitions. he also has a quite good docu on how to set up the whole alexa skill stuff :thumbs_up:

is there anyway to integrate hotword with xscreensaver so i can blank the screen at 10 minutes and it pops back on whenever i say the hotword to the mirror ?

I think possible.
With MMM-notficationTrigger, you can override HOTWORD_DETECTED notification to any notification for any other modules.
So, If you have some module which can awake screen (I don’t know whether really that kind of module exists), it is possible.
If it doesn’t exist, hmmm. you might be able to fork this repository and modify it for that purpose.

haha im a newbie when it comes to coding and finding the right lines but ill have a look arround to see if i can fix something up. i know xscreensaver can be turned on by the following command in terminal:

-activate Tell xscreensaver to turn on immediately (that is, blank the screen, as if the user had been idle for long enough.) The screensaver will deactivate as soon as there is any user activity, as usual.
It is useful to run this from a menu; you may wish to run it as

sleep 5 ; xscreensaver-command -activate
to be sure that you have time to take your hand off the mouse before the screensaver comes on. (Because if you jiggle the mouse, xscreensaver will notice, and deactivate.)

so i think it should be possible to link a hotword to that line to execute it

@themc @myself the correct command would be

-deactivate
This tells xscreensaver to pretend that there has just been user activity. This means that if the screensaver is active (the screen is blanked), then this command will cause the screen to un-blank as if there had been keyboard or mouse activity. If the screen is locked, then the password dialog will pop up first, as usual. If the screen is not blanked, then this simulated user activity will re-start the countdown (so, issuing the -deactivate command periodically is one way to prevent the screen from blanking.)

If you want just to use MMM-Hotword as screensaver-awakener,
modify node_helper.js ;

// add this in line 1:
var exec = require('child_process').exec
...
// around line 86
.on('hotword', (index, hotword, buffer)=>{
  exec ("xscreensaver-command -deactivate", (err, stdout, stderr)=>{})
...
