Part 2 (solution)
At this point, I was at a complete loss. So, I PMed Yo ssi, who graciously walked me through the process via text message...
I needed to download
Fing to find what the updated IP address was and enter that into my browser.
Once I did that I sent a screenshot of the configure template and Yo ssi customized the files for this type of device and emailed it to me. I needed to first load a mini file and type something in the console options and then load the full file. Once I did that, it showed up again in the wifi list as melachaplug. I connected to the wifi and put the IP in the browser and voila I had a functional melachaplug.
This whole time it was connected to a novelty candlestick dusk-to-dawn lamp with the sensor covered so it should be on whenever the smart-switch was on. I tested the toggle a few times and it worked.
Yo ssi encouraged me to wait to see if it works over shabbos with the zmanim, so I removed the tape and left it by the window in a room with the light off and it was off for the whole shabbos.
So, after shabbos, I installed it under my dishwasher.
