PIR-Sensor - put your mirror to sleep if not used

phrazelle

Thanks for the module - this is fantastic!

I have a PIR sensor attached and it works as desired, but when the HDMI signal is cut to the TV, I get a “No Signal” message on the screen from the TV itself because the RPi isn’t sending signal anymore.

I’m wondering what the best solution would be. My head goes to hiding all modules instead of turning the monitor off so MM is still on but a completely black screen, or somehow send the RPi into a sleep state but keep the HDMI active.

Has anyone else tackled this issue?

@phrazelle The idea behind it is so that when the HDMI is disabled you would get the no signal. You then set up the TV/Monitor to go to sleep if no signal is found.
Check your TV manual for power saving settings.

@McSorley Thanks for the response!

Unfortunately my TV doesn’t have a sleep mode option. It automatically displays the No Signal message and turns off after a few minutes of no signal. To make that more difficult, if the TV is turned back on with the remote, it loses the resolution settings and blows everything up until the RPi is rebooted.

I’m not sure how to address this, but I think it would be ideal in my circumstance to have this module, but triggered by the PIR sensor. Idk if I can finagle that, but I suppose I can give it a shot.

Do we still have this problem with the node version? (v5 works, 6 not)

@phrazelle hi! did you find a way to disable this message? i have the same annoying one :)

phrazelle

@bibi Yes! Here is the post I submitted around the new module. Remember that you still need the MMM-PIR-Sensor module by paviro installed for this to work.

@phrazelle interesting! thx a lot will check this :)

Yay! I’ve finally solved my blank screen issue, now I’ve the same problem as @DirkS… After a while the screensaver activates, the screen becomes dark and even if I wave in front of the sensor the mirror doesn’t go on again…
@paviro any idea why?

Nevermind, I’m back on the white page problem… It keeps saying “Error: Module version mismatch. Expected 50, got 51”

I tried either: npm rebuild --runtime=electron --target=1.4.0 --disturl=https://atom.io/download/atom-shell --build-from-source
and: npm rebuild --runtime=electron --target=1.4.5 --disturl=https://atom.io/download/atom-shell --abi=50

but it doesn’t change…

@AlessandroRa
Please run npm list and check for your electron version. Then rerun the command you already tried with the right version number
