The multi-device feature allows you to access multiple Allegro Network Multimeters from a single master appliance. Access to the remote Multimeters is routed through the master appliance so the web user does not need to have direct access to the target devices.
Features like the Path measurement also use the multi-device settings to access the remote appliance for the measurement.
As soon as a remote multi-device is active, the top menu shows a drop-down menu for you to be able to select the current view. All measurement data shown in the web interface are from the selected device.
List of remote devices
The first part of the page contains the list of all configured remote devices. It shows the host name or IP address for the corresponding device and an arbitrary description for each device which can also be changed.
Next to the description, details of the SSL certificate of the remote device is shown so it is possible to verify the correct certificate.
The last column allows you to activate or deactivate devices and remove them completely from the list. Only activated devices are actually contacted and made available in the top selection box. It is also possible to update the firmware of the remote device with the version of the master device.
The settings of the master device can also by synchronized to the remote device.
Add a remote Multimeter
Below the list of registered Multimeters, new devices can be added by entering the host name or IP address, optionally setting a description for the device, and the login credentials.
Master device description
The master device can also have an arbitrary description to make it easier to select it from the top selection box.
It is possible to update remote devices to the same firmware as the master device. The downloaded firmware file must exist on the master device and is used for uploading to all remote devices. No internet access is necessary.
The firmware update will trigger a restart of the processing of the remote Multimeter. In case it is running in bridge mode, the link will be interrupted for a short moment!
Each remote device can be updated separately by clicking the "Update firmware" button in the action column. The status column will show progress information and whether the update was successful.
It is also possible to update more than one device at a time. You can check the checkboxes of one or many devices and use the button "Update firmware of selected Multimeters". All checked and visible devices of the current page will be updated. The button "Update firmware of all Multimeters" will perform the update for every configured Multimeter regardless whether it is selected or not.
If the firmware version of the remote Multimeter is already the same version as the master device or prior to version 3.0, the update is not performed.
It is possible to synchronize the overall settings throughout an Allegro Network Multimeter (core settings), from the master device to all the remote devices. Similar to the firmware update, it is possible to synchronize one, many or all remote devices at a time.
Management interface settings, multi-device settings and user management (roles) cannot be synchronized between Allegros.
Attention: The settings update will trigger a reboot of the remote Multimeter(s). In case it is running in bridge mode, the link will be interrupted for a short moment!
