MMM-PIR-Sensor-Lite does not switch HDMI off

[Volkae]

My MM works fine but I have a problem using MMM-PIR-Sensor-Lite. The modul is running, the countdown is shown on the MM but when the countdown shows 0 it does not switch HDMI off so the monitor is still alive.

What can I do??

@Volkae this module requires python3, which is not installed by default… and not listed in the requirements

[Volkae]

@sdetweil
Python3 was already installed (up to date).
Module seems to work fine but does not switch HDMI off…

@Volkae so have u tried the command it uses, on the terminal window

from the code

/usr/bin/vcgencmd display_power 0

make sure to do this over ssh, so you can turn it back on

/usr/bin/vcgencmd display_power 1

[Volkae]

@sdetweil
then it shows me:

display_power=1

HDMI is still alive…

[sdetweil]

@Volkae those two were off and on

if you do off

does it turn off?

[Volkae]

@sdetweil
No, it does not switch HDMI off

[sdetweil]

@Volkae works perfectly on my pi 4…

what pi version are you using?

[Volkae]

@sdetweil
I´m using a pi3.
Maybe that´s the problem??

@Volkae worked on my pi3 as well…
