Code to check WAN IP and execute code

Noob here, and looking for the easy way out :slight_smile:

I need to create a scene than runs at certain intervals which can poll my WAN IP, check it against a string, and then execute an http command if true (or false).

Conceptually:

Find “WAN_IP” via external service (ie “What is my IP address? • Ipcim.com”)

If “WAN_IP” contains “*.bidoof.com” then “http://x.x.x.x/command.cgi?user=admin&passwd=1234&device=0&command=1”

Can someone help me out with the lua code?

Thanks in advance.

Edited to add: more precisely, I want to compare against my WAN hostname.
