hi, i have a lot of time … [#StayInHome #COVID19]
so i can help you to configure from begining

what addons do you want to use ?
AMk2 don’t show icon by default, just because default interface is like Google Nest
so i will be showing only when activating by hotkey

@Bugsounet Hi. Thanks a bunch. Something good from the virus, hurray!

So the mirror functions with a PIR sensor installed in the frame. It hangs where there is a lot of traffic, so a hand gesture along side the frame activates the screen using DPMS -> DISPLAY=:0 xset dpms force on (only way I could get the screen to turn on again was with DPMS). No movement and the mirror turns on again in x time.

So what I would like to accomplish is, when the screen is activated, it should start listening for a google assistant hotword.

Would that be Hotword and PIR? Depending on how Assistant2Display works, that could be interesting as well, but for now, I just want to get it working.

actually, i can’t do this (not coded)

I have coded this:

wake up screen with voice (when calling assistant)
delay turn off screen if mirror is not used
if used pir detector : wake up the screen
if used snowboy or MMM-Hotword and pi sensor : keyword activator is turn off when not used and need pir sensor to wake up

you can do that what addon ;)

You can emit HOTWORD_PAUSE and HOTWORD_RESUME notification when you need if your PIR module could emit these notifications. Or to translate different notifications through MMM-NotificationTrigger.

Does the keyword activator (I guess that is the code listening for a keyword?) pay a toll on the electrical bill and thus, you would like to turn it off?

Isn’t the snowboy/HotWord, PIR sensor and governor combo a means of achieving that?

@Sean So the python script that wakes up my screen along with the PIR, could potentially also emit a HOTWORD_RESUME and HOTWORD_PAUSE to the assistant along with executing a shellscript for turning on/off the screen. That sounds like the right way to go, but I have no clue how to do that and not enough time to figure it out :)

for resume :

@MilkShake have a misconfig MMM-Hotword and turn on all AMk2 addons (include snowboy and porcupine)

so i will never works like this.

We change like this:
desactived MMM-Hotword
used: snowboy addons with “computer” keyword, Assistant2Display addons

and works:
notes : he have an RPI 4 (4go) , he use pir sensor.

he send me his screen monitoring to add it in screen addon
I rewrite screen addon for solve screen issue
because actually only RPI3 is supported

we will try screen/pir addon with his config tomorrow for sync with all AMk2 addon (Assistant2Display inclued)

and he should have CPU less (and electricity) usage on screen sleeping:

when screen is on (wake up by pir sensor) snowboy will be on and display on
when screen if off (setting by inused delay) -> all module is hidden, display is off and snowboy is off

it’s actualy my personnal AMk2 config

Edit:
we finish the configuration and everything works ;)
now screen/pir are linked to snowboy and Assistant2Display for more cpu save (and electricity)

MilkShake

It works really well now. Mirror and assistant/addons turns on when the pir detects motion. Awesome combo of AssistantMk2 and Addons.
