Issue HDMI going to sleep modus after update

@htilburgs

from the readme pir_mode should be 2 for Raspbian 12 - maybe mode 1 works too

try to use mode: 8 (ddcutil) which works great for me. It turns on/off the monitor completly.

I will try this and let you know the results.

I’ve tried WAYLAND and X11, both same result on mode 8: “Display not found” error.

When I do “ddcutil detect” I got this result.

Invalid display
   I2C bus:  /dev/i2c-20
   DRM connector:           card1-HDMI-A-1
   EDID synopsis:
      Mfg id:               SAM - Samsung Electric Company
      Model:                SyncMaster
      Product code:         2966  (0x0b96)
      Serial number:        
      Binary serial number: 1 (0x00000001)
      Manufacture year:     2014,  Week: 2
   DDC communication failed

As I told earlier, it worked fine on mode 9 (X11) and mode 10 (WAYLAND) with PIR_MODE 1 and 2.
The problem has come since the update of my rPI to the latest version of Bookworm.

So I think the problem (Monitor goes to sleep, but does not turn off anymore - Sleep=170Watt - Off=0Watt) is in the rPI more than in MMM-PIR.

Any advice??

Hi Sam, this is not possible on his Github site
Went to his website (in French), but there also no possibliity to open an issue.
