I updated the script last week.  
And I thought “I’m getting the wrong IP address” meant as “I’m getting an IP from something elsewhere” 🤪.  
Appearantly you just missed a few numbers.

This one should return any IP:

This is what I have:

I changed it back to:

It doesn’t change the result:

The last screenshot is the output of the HTTP GET trigger, [Result]  
So, you’ll need the output of the Homeyscript card in the timeline notification card, which is [_Response_]  
I hope this does the trick.

I recommend using the first script in your post.

Instead of using a brittle method like parsing an HTML page you can also use [any of the dozens of available API’s](https://www.google.com/search?q=my+ip+json) that provide your IP-address in JSON format:
