My son got me a Ras. Pi for X-mas which I'd like to stash it inside my driveway gate control box for (really) remote operation. After stumbling around with Python, the peeps on the Pi forum said to check out Node-Red. My plan is to (make?) a phone app to run it. So far, I got the "IoT MQTT" app and have made a dashboard with it, but it's pretty clunky looking. I signed up for NOIP and have a page there (can't seem to see it even though it pings OK). Not really sure what I should be seeing while using it either. My thought was NOIP was simply a pass-thru from outside to my Pi. I have my home router configured with port-forwarding to the Pi's IP4 addy, still seems there's something missing though...
Anyhow, the app will have one momentary button to start/stop a cycle, two LEDs for open and close verification, and a slider to show where the gate is in it's travel stroke.
Before I do anything with the gate, I'd like to get the app to "see" the Pi and be able to interact with it. Could someone please generalize an outline to get that far?
