Conditional Control Relays with N-Button

N-Button software allows you to create widgets to control relay boards.  You can not only simply turn relay on or off, but set up conditional rule to control relays.

Here will show you an example about how to set up conditional rule to control relays.

We will use the push button of push notification board to control relay board. Both of the push notification board and relay board are from National Control Devices. We already have a blog about how to control/toggle relays by push notification board.

We will add conditional rule to avoid Relay 1 and Relay 2 to be on at the same time. That is,

  • When Relay 1 is ON, Relay 2 can NOT be ON;
  • When Relay 2 is ON, Relay 1 can NOT be ON;

This might be happened when you use relay board to control two different doors or valves, if you don’t want them to be opened at the same time.

Step 1: Be sure you already installed N-Button software, connected push notification board and relay board to your computer.

Step 2: Run N-Button Lite or Pro, add push notification board and relay board to Device Manager.

Step 3: Add two Relay Buttons to toggle Relay 1 and Relay 2 separately.

Step 5:  Add two simple Conditions for Relay 1 and Relay 2 separately. The initial status of conditions are Meet. The condition works as a mark for relay channel. The relay will be controlled as long as the condition is Meet.

For Push Button 1, when the button is pressed there are 5 actions will be executed.

  • Lock Relay 2 : It is a Condition Action to set the Condition 2 (Mark for Relay 2) as Not Meet.
  • Turn Relay 1 On: It is a Relay Action to turn Relay 1 On.
  • Wait: It is a Wait Action. Input the time you want the Relay 1 keeping On.
  • Turn Relay 1 Off: It is a Relay Action to turn Relay 1 Off.
  • Unlock Relay 2 : It is a Condition Action to set the Condition 2 (Mark for Relay 2) as Meet.

In the same way, the 5 actions for Push Button 2 shown as below.

We have finished all settings. You will see 4 widgets on your desktop.
