Small changes to the remote nodes, they now actually broadcast the data to a predefined web endpoint.
A bunch of work on the central node. It now is a functional flask server, and can register devices in a mysql database upon request. This was a ton of work for me, because I have never built any sort of website, nor do I have experience with mysql.
I also got the very start of the resource transmission working.
The central node also has the capability to reject the device registration, should a device with that name already be registered. This is the type of thing that I will implement for use with the remote node installer, where it will try to pick a name, and tell you if it worked or not.
The video below is what I have working so far for the device registration. The program shown at the start is a mysql database GUI, which has been very helpful. (sorry for music in background)
