In an EclerNet system, only one device can act as a UCP Server unit: this device will run the EclerNet project and perform the webserver function, serving UCP (User Control Panel) panels. If this function is performed by a WPNETTOUCH for itself and for the rest of the UCP clients (WPmSCREENs, WPNETTOUCHs, smartphones, tablets, PCs, etc.) in the network. You can choose in each WPNETTOUCH which panels it should show and even which of them will be the default panel (at startup and after a time of inactivity). You can also display the same panel on different screens without problems. Remember to disable the Enable UCP Server function on non-Master devices to avoid errors. Check the image by clicking here.
