Mirror turning black after a while

@Mykle1
Thanks. I’m pretty sure the monitor is on, because if I connect a keyboard I can start a terminal and it doesn’t look like it has been down in sleep mode (should take longer time to wake). I’ve also tried to turn off/on screen with MMM-RemoteControl just to make sure, but no luck. I’ll double check the status light when the error occurs again.

Hello,
I also encounter this problem episodically. Magic mirror works normally but no module appears on the screen a simple ctrl + R (reload) is enough to refresh and make reappear modules.

@Chris
Did you have the same error on the old version or did it appear with the latest?

Is there any kind of “sleep” mode on the system itself?
The node log probably doesn’t detect what’s going on but maybe the console log would show (unfortunately, it’s reset when the browser window is refreshed). I’d start MM in dev mode and wait for the crash, then check the browser’s console log.

@doubleT Thanks for the tip! I will try dev mode and report back.

Hello,
it is true that this is happening since the last version.
I did not pay much attention to this because it was during an attempt to install a module that caused me a lot of trouble. I thought it was just that.
As I told you, it’s still very episodic, it must have been more than two days since it did not happen.

Hello All, is this issue fixed? I still have this issue and I get back the screen only by ctrl + R. I am experiencing this issue only after the recent update.

@bimalnair I haven’t done any more research. But now I have started in dev mode and will see if the console log says anything useful. But it usually takes some hours before my freezes, so I will know later today (hopefully).

Another test is to remove module by module to see if a certain module is causing problems. Or the opposite, start with only one module and see if it will freeze. Can you check which modules we share? Maybe we can narrow it down a bit.

I am using the following modules
default/alert
default/clock
default/calendar
default/currentweather
default/weatherforecast
default/newsfeed
default/compliments
MMM-ShipmentTracking
MMM-Traffic
MMM-ImagesPhotos
MMM-dht22

Will try disabling each module

Hello,
I think it would come from one of your modules because I do not encounter the problem since I put my mirror with my usual modules. if that helps you, it happened to me when I tried to install and set up the MMM-Assistant.
