This is a modification of the MM-Hide-All module (https://github.com/masters1222/mm-hide-all) by masters1222. It requires the MMM-PIR-Sensor module (https://github.com/paviro/MMM-PIR-Sensor) by paviro to be installed as well, as the hiding/unhiding is triggered by the “USER_PRESENCE” notification sent.
This was created by Josh Mclaughlin to circumvent an issue with the MMM-PIR-Sensor module where a TV doesn’t have power saving settings and killing the HDMI signal from the RPi forces the TV to shut off automatically.
This essentially brings up a black box to cover the screen after a set amount of time that disappears upon a USER_PRESENCE notification from the MMM-PIR-Sensor module.
@phrazelle As someone who is having trouble with the MMM-PIR-Sensor module, this is a lifesaver! Going to give it a try today.
Great addition to the PIR-Sensor module. I’ve got it working on my mirror, but the only issue is that when the sensor detects movement, the screen only stays active for about a second, then goes to sleep again. Is there a line in your code that I could modify so that when movement is detected, the mirror stays on for a set duration (maybe 4 minutes)? I’ve been looking at the code but I’m new to this so I don’t really know where to start.
I think this is not a software problem.
On your Sensor are two variable resistors.
One for the sensitivity and one for the delay time.
Take a screwdriver and adjust the delay time.
@lolobyte thanks for your reply. I am actually not using a PIR sensor, but a microwave radar sensor as I wanted to put the sensor behind the glass. After looking into it, I found that I can install a resistor on the sensor to set delay to 30 seconds.
If I want more than 30 seconds, would placing a higher resistance resistor on it work?
Please send me all your information what you have because i want to build and test it by my mirror.
Agreed, I think altering the delay on the sensor would fix the issue.
That being said, the microwave radar sensor sounds awesome! I’d like to see it in action as well.
I’m struggling to get this working, i’m just receiving a black screen that doesn’t want to exit. I’ve tested the PIR sensor with a simple python script and it works fine, i’m just having trouble getting it to integrate with the mirror. Any advice?
