MMM-PIR-Sensor: Everything works fine, just one thing not...

Medo

My sensor is working fine for months now. It works as designed (shuts my mirror down after 5 minutes and is reactivated if someone enters the room or goes by).

But i noticed this:
After a reboot of the whole PI mirror system, the screen isn’ t turned off by the MMM-PIR-Sensor-module (even after waiting for more than an hour or more - i think it would be on forever). Only if someone goes by, the sensor shuts down the screen (monitor) for a millisecond and immediately after that, turns the screen on again. After that, the PIR sensor works fine like every day before…

Does any one of you ever had a similar behavior of a PIR sensor configuration?

Thanks!

Hi Medo,
i think i read something that after a reboot you have to wave your hand (for example) in front of sensor once, so the sensor is active.

Thanks, did not know that this has to be done to “activate” a PIR sensor…Interesting…hmm…

Does anyone know, if there is a method that this can be “simulated” in any way?

one idea is to just put the tvservice -o command in your rc.local.
before that u should do a little sleep.

like this:

sudo nano /etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

sleep 60 &

tvservice -o

exit 0

So on every reboot it will wait 60 seconds (just to let everything start like MM) and then turn the monitor off.

Sounds like a great idea! I will try that soon and will geht you a reply if it works! Thanks for that possible solution…

@cruunnerr
Your solution worked like a charm.
Thanks!
