@JMac you can still use lite.
MMM-Pir haa lots of different modes

@sdetweil
So if I stick with MMM-Pir am I right in thinking if u set the mode to mode 4 in the script it would turn the screen off via the HDMI?Just read that it is set to mode 1 by default which uses vgencmd but my screen and pi are connected via HDMI.
Would be handy to get this one turning the screen off entirely (if possible) and use the PIR to turn it back on, as the rest of the MM is working nicely.

@JMac I do not ‘know’ the correct mode… it depends on the hardware and OS
on pi3 the HDMI port is one way, out… you can only turn it on/off.
the monitor(energy star compliant) put up a big NO INPUT screen when the port is turned off… fun!.. for some timeout (max 15 mins) and then POWERS OFF…
the spec said AND STAYS OFF til MANUALLY turned on…
darn mess for us…the pi4/5 (and maybe pi02w) hdmi port is bi-directional, so one can GET status from the other side… in software (CEC) … (if the code is supported and installed on the OS)…
my 55in TV os CEC compliant, BUT it will turn off, but not back on… sorta not useful… oops… no firmware fix yet, 4 yrs later
now later energy star also provides for STANDBY mode… so it COULD come back on… i don’t ‘know’, but I think this status is NOT known on the OS side.
I know that the author is constantly fixing/enhancing the module
it is INTENDED and DESIGNED to turn the output back on with movement… -
@sdetweil That was exactly how PIR sensor lite worked on the same pi 3.
screen would turn off after time interval - i had it set to 5 minutes - pi would detect a hand swipe past the PIR sensor, pi would wake the screen up and the 5 minute cycle would start again.do we (you) think the mode 4 for HDMI in this module will function the same?
