All my Google rewards are belonging to him...

For several years I connected to my home surveillance cameras via dynamic IP. It went months at a time without change, very infrequent. Created a tasker profile, android app, to pull IP daily when my alarm went off in the morning. If IP changed I would get a notification with the new IP address. I could then reconfigure my connection when needed.

I'd recommend go buy his other app(s) in support. I did...After it was no longer working.
