LCD display allows you to display, cyclically, the data you’ve chosen to show: all data of your station, only one module data, outdoor data, or one single type of value for all modules or just one module. You can specify the size of the display, its design (colors, design, etc.) and the cycle speed.
Note that this live control displays min/max values when available, signal and battery level of the modules, and alarms on some value types.
