      Problem is the fact that the CONFIG message is sent from the frontend only at the loading of the page (subclassing START). If the page is still open in the browser it will send SCAN_NETWORK requests periodically which will lead to the situation where the config object is empty when the scan is to be executed, if the service has been restarted meanwhile.

      Furthermore, if a reload of the page is executed, a CONFIG request is sent to NODE_HELPER which might be busy scanning and it seems as if there is no escape unless the correct sequential order for CONFIG and SCAN_NETWORK is used.

      To verify:

      1.) Stop loading of the page in browser or navigate to an other page so no SCAN_NETWORK will be created for the device status updates
      2.) Stop + restart MM
      3.) Reload page / enter start URL

      This will lead to the correct order and the programmatic solution is to check if the config object is filled before executing the scan. If not, it has to be reloaded, the CONFIG request in NODE_HELPER can not be used as it uses the payload from the frontend.

        @todro oh yeh that will be a mess. Hadn’t thought of that, electron will shutdown, but remote page wont

        That will be a problem for many modules!

            @jthirasilpa ok. Need to open the developers console, ctrl-shift-i on the keyboard, select the console tab and scroll up to see any errors.

            U can also filter by module, by putting part of the module name in the filter field. Network, for example.

            The code should be sending messages to the module name.js

                  Hi Sam - yes - changed to top_left. Still “Loading…” If I go into the developers console, and search in the text field for “error” it only brings up the following (although the top of the console indicates that there are 3 errors)

                          Hi Sam - they were not at the time of the scan, but they have been picked up in console messages previously. For example:

                          Shouldn’t that then show up on the Mirror?

                              @sdetweil Hi Sam - I appreciate your assistance. I am actually asking that question legitimately out of ignorance. I assume that if it appears in the console as follows:

                              Object { ipAddress: “192.168.1.11”, name: “Champagne”, icon: “server”, color: “#ffffff”, showOffline: true, online: true }

                              then it would be show up in the Mirror, but maybe there are several steps in between…

                              In any case - thanks for your help.

                                @jthirasilpa it matches the IP address with the scanned Mac addresses.
                                If not in the Mac addresses it is not shown.

                                In debug mode I get a big blast of the Mac address info displayed every time there is a scan

                                  @sdetweil OK - do not have access to machine now, but will have a look later. Thanks.

                                    This is one of the devices from the config.js

                                    { ipAddress: "192.168.1.11", name: "Champagne", icon: "server"}

MMM-NetworkScanner received a notification: IP_ADDRESS 
Object { ipAddress: "192.168.1.11", name: "Champagne", icon: "server", color: "#ffffff", showOffline: true, online: true }

                                    This is from the console:

                                    MMM-NetworkScanner.js:70:30
MMM-NetworkScanner IP_ADDRESS device:  
Array [ "Champagne", true ]
MMM-NetworkScanner.js:80:31
MMM-NetworkScanner is updating device status. 
Array [ "Champagne", true ]
MMM-NetworkScanner.js:284:31
MMM-NetworkScanner Champagne is online

                                    Strangely when I run sudo arp -scan -l, this device doesn’t appear. But doesn’t the information from the console suggest that it should be displayed?

                                    Conversely, the arp scan does find 192.168.1.15, but console displays this:

                                    MMM-NetworkScanner received a notification: IP_ADDRESS 
Object { ipAddress: "192.168.1.15", name: "Millie", icon: "server", color: "#ffffff", showOffline: true, online: false }
MMM-NetworkScanner.js:70:30
MMM-NetworkScanner IP_ADDRESS device:  
Array [ "Millie", false ]
MMM-NetworkScanner.js:80:31
MMM-NetworkScanner is updating device status. 
Array [ "Millie", false ]

                                    I would think that one of these would be displayed on the MM.

                                    Any further thoughts? Thanks.

                                      @jthirasilpa are those wireless? The arp scan only did Ethernet connected devices

                                        Those devices are ethernet connected. Also, I was just checking the logs and there are a lot of ip addresses and:

                                        0|mm       | [20:52:38.389] [LOG]    MMM-NetworkScanner is performing arp-scan
0|mm       | [20:52:38.419] [LOG]    MMM-NetworkScanner is performing ip address scan

                                        but no MAC addresses - which you seem to have in your logs.

                                          After a complete reinstall of MM, I finally managed to resolve this. After reinstalling the original NetworkScanner module and using macaddresses to add to the config.js, I kept getting the “sudo requires your password” message. I went through node_helper.js and the only command that appears to require sudo is arp-scan. So I amended sudoers to allow sudo arp-scan without password using:

                                          sudo visudo

                                          and then adding:

                                           # Allow arp-scan without sudo
username ALL=(ALL) NOPASSWD: /usr/sbin/arp-scan

                                          This allows sudo arp-scan to run without a password, while maintaining password requirements for other sudo commands.

                                          Many thanks to Sam et. al. for input on this issue.

                                            @jthirasilpa cool. Thx for the update. Using the updated file w password support should have allowed without sudoers
