Thank you Samer for your prompt reply. This looks like it might work for me. A couple of follow-up questions. Let me take a stab.
1. I assume that i would go out to “GoDaddy or equivalent and register a name. For example. MySprinkler.com.
2. Then I would go into the router and activate DDNS with this domain name.
3. Then I would go to the app and where replace the current IP with the domain name????
4. What about port forwarding? Is that part of the DDNS in the router or is that included with the domain name.?
Am I on the right track? Great job on the App.
