Anynet+ HDMI CEC

MDLefevere · Aug 16, 2021, 6:34 PM

Hi all,

I’m running into an issue were i’m curious if others are experiencing this.
I have a Samsung CEC+ compatible TV which in combination with MMM-NewPIR works.

The strange thing i’m facing that it works most of the time.

Countdown from 10 to 0 --> TV goes into standby.
Motion detected after several minutes --> TV turns on.

When there is like half an hour of no motion i can swing my head in front of the PIR sensor but nothing happens.
The statuslight on the PI defenitly get’s some activity at the moment it gets motion detected.
…

I’ve checked al my TV settings and there is no other powersaving mode active… Like none!..

Cheers :)
Maurice

@sdetweil

What module do you use?.

sdetweil · Aug 16, 2021, 9:40 PM

@mdlefevere i don’t cause it doesn’t work…

i have tried all the modules, and all the commands

i blank the screen, and use my webcam for motion detection

@sdetweil

So that will be my next option if i can’t get this to work.

Do you switch it completely off at night or do you leave it with a blanc screen 24/7?
You have an estimation of how much power i draws in a day?

sdetweil · Aug 17, 2021, 2:28 PM

@mdlefevere blank screen when I’m not around.

power draw. the 55 is 82 watts/hour on, .5 off
the 43 is 65w/h on, also .5 off

@sdetweil

You mean 5 in standy of with a blanc screen?.
If that’s the case it’s not worth all the trouble of trying to get CEC to work ;)

sdetweil · Aug 17, 2021, 2:48 PM

@mdlefevere no. 0.5 (one half of one watt) is off/standby
blanc screen is on, so 82 or 65 for me…

I have not measured power consumption

I have 5 SBCs plugged into the same circuit (w the 55in, 4 hdmi ports)
pi0
2 - pi3 (1 runs homeseer to control my lighting)
pi 4
odroid

and another pi4 I just got with the 7in touch screen and case

and then jetson nano in the hall (with the 43in)

and a mac mini
and my intel desktop (never off, but I power off the screens at night when i leave the office)

@sdetweil

Thanks for the info.

I’ve setup a Pi3 with CEC and this seems to be working.
Even after a long time the TV turns on. My Samsung also instantly recognized the Pi3 as a CEC device unlike the Pi4. It had some struggle with the new Pi.

Could this be a Pi4 related issue?, or just Samsung?.

@mdlefevere no idea… CEC doesn’t work from pi3, but does partially from pi4…
not from any other SBC
