    This has been running great for over a year. I finally got around to cleaning up the code a bit and posting it for those interested.

    Got it working! :)

    Attached to the 9vdc barrel jack directly to power the ESP8266:

    Double sided tape to hold it in place:

    Looks like this may solve all of my concerns. 5-12v regulator and 5v to 3.3v logic shifter on the UART pins. :)

    Yeah, this is a 9v white. I was hoping to avoid an additional regulator since I had the ESP-01s just laying around. I ordered some Wemos D1 Mini clones with a 5v regulator. A little bigger, but maybe a drop in depending on the built-in regulator. Looks like I may also need logic level shifters as well. :(
    How much overhead is left in the AC5 white’s 5v regulator?
