N-Button suports up to 255 widgets.
If you need less widgets, you can use N-Button Lite. It only supports up to 8 widgets.
It's very easy to add and modify the widgets by N-Button Manager. There are four types of widgets, Relay Button, Relay Status, A/D Meter and Customized Button.
Relay Button widgets are used to turn on/off relay directly. It is never so easy to control relays before.
