To send HTTP request, you need create a  Customized Button.  Here are the steps.

1. Click “Customized Button” on N-Button Lite/Pro Manager to show its Properties panel.

2. Click “Setting” on “Properties – Customized Button” to show “Click Action Setting” panel.

Create Customized Button

3. Select “Send HTTP Request” for Action Type and input the HTTP Request.

N-Button Send HTTP Request

Here, the Action Device can be ignored, because the Web-i relay module is connected to network, which can be accessed by all computers in same network. If you want to send HTTP request to the Web-i relay module from several different computers, be sure not connect the Web-i module with one computer. It should be connected with a router.

The HTTP Request includes the command to control the Web-i relay module. Here is the format for HTTP request to control Web-i relay module.

http://[webi_ip]/cgi-bin/runcommand.sh?[random number]:cmd=[command]r1t300

webi_ip: IP address of web-i relay module.

command: control command

For example:  http://192.168.1.18/cgi-bin/runcommand.sh?423:cmd=254,108,1r1t300

The IP address can be found in “Connection Setting” panel just like we mentioned above. You also can find it on your router setup page.

About the command, here “254, 108, 1” is the command to Turn On relay. The “1” indicates the Bank Number. If the Web-i relay board has relays less than 8, the board has only 1 bank. The bank number will be 1. Each bank have 8 relays. If the board has more than 8 relays, there are more banks on the relay board. Relay 9th to 16th belongs to Bank 2, relay 17th to 24th belongs to Bank 3. etc..

Here are some frequently used commands. You can get more commands from related manual of relay board.
