Using a NodeMCU and RXB6 to Publish Doorbell Presses to MQTT

The Problem

I have a Eufy Video doorbell that does a great* job with push notifications, 2K video streaming, and providing basic doorbell functionality; all without a monthy subscription. It comes with a basic 433MHz chime that you can pair and put anywhere in your house. This doesn't really work well with a two story house... it is no where near loud enough to hear it upstairs.

* Despite notifying me that the tree in my front yard is a person when it is windy enough.

Getting Started using the Destiny 2 Api
An annotated guide to some of the public endpoints available for examining a user's
characters, items, and clan using the Destiny 2 API. You will need to use your api key for
this to work. Just insert it as a string where it says <my_api_key> in the beginning.

It is broken into four parts:
    0: Imports, variables, and fixed parameters defined
