Here you can set LUCI Studio to log what it’s doing, for debugging purposes. If you experience any problems, set this to Normal and LUCI will write a *.csv file. Send this file to our support centre and also include your *.lsup so we can see what your settings are.
Keep log file : Set the timespan the log files will cover, so “per Session” will delete all previous sessions logs.

Log files are created in a special csv format with | as column separator and ‘ as text delimiter. You can set these at the import  dialogue of your spreadsheet editor.

NOTE: Creation of Log files can slow down the PC or exhaust your drive. Use with care

A separate window for network settings.

Network interface
Choose the network card you want to use (Default selects the Systems choice). Make sure the selected network interface is connected to the global internet.

Enable UPNP network tools
Universal Plug and Play (UPnP) is a set of networking protocols that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices to seamlessly discover each other’s presence on the network and establish functional network services for data sharing, communications, and entertainment.

LUCI STUDIO can use UPNP to set a port-forward rule in your router, and determine more info about your network should there be a problem. The Network information is then displayed in the Network Info field.

NOTE: Not all routers support UPNP by default, make sure it is enabled in your router at least for this computer if you want to use this feature.

Network Info
When UPNP tools is enabled you can see if your router is UPNP capable, your local PC’s IP address, your Global Internet IP address and a complete trace from your PC to the Internet with all network ip translations.


Every LUCI STUDIO instance can be controlled by Ember+. To identify the instance you can give it a “name”, a unique “port” number and optional “show the given name as window title” and/or in a coloured “group tag” of the LUCI STUDIO instance. Group tags can be used to define LUCI STUDIO groups like location / project / usage groups.

The port number has to be an unique port for your network for this instances of Luci Studio. Only if you want to control this Luci Studio from outside your network, it has to be TCP port-forwarded in your router ( see for more details our How To portforwarding but set it for TCP data). You can test this with the “Test Reachability”.

The value at “Snap grid on Move” is the number of LUCI STUDIO instances that are displayed on one row when the snap grid is enabled. The windows will “lock” in a grid and move together.

Note: This section is only available with the Ember+ plugin license.
