Black screen (only with cursor visible) when waking mirror with MMM-PIR-Sensor after long sleep periods

[Matthew]

@sdetweil next time I get the black screen I’ll take a look!

[Matthew]

@sdetweil It says that devTools was disconnected from the page. Once page is reloaded, DevTools will automatically reconnect

[sdetweil]

@Matthew hmm. let me think about another debug approach.

[A Former User]

@sdetweil I remember that I have some problem with an npm library with it (before I start to code)
I don’t remember how I solve it

After you can try my pir module if you want

[sdetweil]

@Matthew install this module
https://github.com/sdetweil/MMM-Logging

note that this is a modified version of this module, written by someone else… but I needed to do similar debugging a while back

make its module entry in config.js the top of the list, like this

modules: [
        {
            module: 'MMM-Logging',
            config: {
                       echoRemote:false,
            }
        },
// other modules
    ]

let everything else default

this will collect all the browser logging and console logging together with timestamps…

then start mm like this

cd ~/MagicMirror
npm start >somefile 2>&1

or use pm2
(all the logging info will be saved in the pm2 logs)

@sdetweil Thank you! I got the error again today, and this is what the logs said.

@Matthew >[2020-08-15 17:22:14.668] [ERROR] Error: listen EADDRINUSE: address already in use 127.0.0.1:8080
that happened on the 15th within 2 seconds of starting…

is that the right log?

that says something is already running … do you normally use pm2 to launch MM?

do pm2 status

[Matthew]

This post is deleted!

[Matthew]

@sdetweil its been a while since I set all of this up, but pm2 is the auto launch right? If so then yeah it always launches automatically

[sdetweil]

@Matthew so, you can’t use it with the npm start…

as I said in the prior post, if you use pm2, then restart mm after adding the logging module (pm2 restart 0) and then see the logs with pm2 logs

pm2 logs --lines=100

or u can direct edit the logs in ~/.pm2/logs

[Matthew]

@sdetweil

Im trying to reply with the logs, but it’s getting flagged as spam

[sdetweil]

@Matthew u can mail them to me. same user ID on gmail

[Matthew]

@sdetweil
