now, to check, this system is case sensitive… so in config.js it MUST look like this, right?
keepAlive: 300, updateInterval: 5, Password: 'pi' // added password (note capital P) }using your password of course
-
That is how the config looks.
Still getting the node_helper line 42 error. Will park this for now. Thank you for spending so much time on this Sam - much appreciated. Will come back to this later in the week.

@jthirasilpa update the current code
cd ~MagicMirror/modules/MMM-NetworkScanner git pullthen you can shutdown and restart the MM app
there was a tiny timing gap where the config info is not yet set, when the helper is asked to scan the network…
let me know
-
Is it bad to have this?
pi@raspberrypi ~ % sudo -l|grep NOPASS (ALL) NOPASSWD: ALL pi@raspberrypi ~ %Edit: To expand further, I have MMM-NetworkScanner running. I do not need to supply a password when I run sudo and I don’t have a password stored in a config file.

Hi Sam - thanks I tried the update. Still getting the same error - from the log:[19:00:49.868] [ERROR] TypeError: Cannot read property 'network' of undefined at Class.scanNetworkMAC (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:42:36) at Class.socketNotificationReceived (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:30:18) at Socket.<anonymous> (/home/jojo/MagicMirror/js/node_helper.js:113:11) at Socket.emit (events.js:198:13) at /home/jojo/MagicMirror/node_modules/socket.io/lib/socket.js:528:12 at process._tickCallback (internal/process/next_tick.js:61:11) -
@jthirasilpa do another git pull from my repo… and try again

Thanks SamTried update. Error log below:

@jthirasilpa weird…
the trace shows, on a timer tick (in the modulename.js) the node+helper received a socket message (sendSocketNotification from modulename.js), and received in node_helper)
the notification is correct, and it starts to rescan the network…but, it has lost the config pointer for some reason…
weird…
please do another git pull
also add debug:true,
to the module config section
let me know
thanks

Thanks. Scan seems to find some devices, but does not display them on Mirror.
Here is output log:

and it says it will scan all the addresses in the devices list, but millie isn’t pinged…
what else do you have in bottom_center? it can get pushed off screen pretty easily…
