@Gooral
I had a similar issue and found out, that MMM-PIR-Sensor and MMM-Remote-Control uses different commands for sleep/wakeup of monitor.

MMM-Pir-Sensor:
vcgencmd display_power 0
vcgencmd display_power 1

MMM-Remote-Control:
tvservice -p
tvservice -o

In my case i was not able to wake up the screen by PIR when i send him to sleep by MMM-Remote-Control and the way back.

Maybe this information helps.

@Gooral yes snowboy might already help, since the hotwords are trained with 3 examples of one person, so only quite similar voices get detected (but will not work when the voices are quite similar)

another possiblity you might want to check out (did not try it myself yet) is

@pnizet Still quite pricey for my taste but I’d love to see a infor-board project based on it. So go ahead and don’t forget to present it here :smiling_face_with_open_mouth:

Btw, it’s not my topic. @Gooral was the one starting this thread. :slightly_smiling_face:

This one will be helpful anyway but I need to trigger a relay from a module using GPIO.
