Thank you, I’ve checked and it is mode 4 for HDMI CEC, I have checked my monitor and HDMI CEC function is turned on, so it should work. After time out the monitor blanks but it is still powered on so I’m guessing so is the backlight, but Ill wait till dark to find out.
Can I just say thanks again for your support with this.

@sdetweil
Many thanks, when I shut down the Pi, I get a No Hdmi message on screen and then the monitor goes into standby.
Is there a way that MMM-PIR can turn off the Hdmi feed?
Apologies but I’m not a programmer, just a hobbyist, you mention CEC commands, how would I implement this?

Having had issues with Pi5 I went back to Pi4b. MMM-PIR works great with pi 4, blanking the screen after timer expires and resetting once presence is detected.
The only issue I have is when the screen is blanked, the monitor backlight remains on, visible at nightnas a glow, the monitor remains powered up, I would have expected it to go into standby?

@schris88
Thx for the info, I guess a lot of the modules require reworking for the Pi 5.
Unfortunately I do not have the ability, totally new to the Pi and programming.

@eyesallin
I’m beginning to think that all this is Pi 5 related.
Also changing to mode 10 as previously stated screws with the weather modules which don’t load. Remove MMM-PIR from config and everything works fine.
It doesn’t help that I’m completely new to all this.

@bugsounet Apologies but I don’t understand what you are asking for?
