NAME
    App::RPi::EnvUI - One-page asynchronous grow room environment control
    web application

SYNOPSIS
        sudo plackup ./envui

DESCRIPTION
    This distribution is alpha. It does not install the same way most CPAN
    modules install, and has some significant requirements Most
    specifically, the wiringPi libraries, and the fact it can only run on a
    Raspberry Pi. To boot, you have to have an elaborate electrical relay
    configuration set up etc.

    Right now, I'm testing an App::FatPacker install method, where the
    packed web app is bundled into a single file called `envui', and placed
    in your current working directory. See SYNOPSIS for running the app. I
    doubt this will work as expected on my first try.

    It's got no tests yet, and barely any documentation. It's only here so I
    can begin testing the installation routine.

    This is my first web app in many, many years, so the technologies
    (jQuery, Dancer2 etc) are brand new to me, so as I go, I'll be
    refactoring heavily as I continue to learn.

    At this stage, after I sort the installer, I will be focusing solely on
    tests. After tests are done, I'll clean up the code (refactor), then
    complete the existing non-finished functionality, and add the rest of
    the functionality I want to add.

    I'll then add pictures, diagrams and schematics of my physical layout of
    the Pi all electrical components, and the electrical circuits.

WHAT IT DOES
    Reads temperature and humidity data via a hygrometer sensor through the
    RPi::DHT11 distribution.

    It then allows, through a one-page asynchronous web UI to turn on and
    off 120/240v devices through buttons, timers and reached threshold
    limits.

    For example. We have a max temperature limit of 80F. We assign an
    auxillary (GPIO pin) that is connected to a relay to a 120v exhaust fan.
    Through the configuration file, we load the temp limit, and if the temp
    goes above it, we enable the fan via the GPIO pin.

    To prevent the fan from going on/off repeatedly if the temp hovers at
    the limit, a minimum "on time" is also set, so by default, if the fan
    turns on, it'll stay on for 30 minutes, no matter if the temp drops back
    below the limit.

    Each auxillary has a manual override switch in the UI, and if overridden
    in the UI, it'll remain in the state you set.

    We also include a grow light scheduler, so that you can connect your
    light, set the schedule, and we'll manage it. The light has an override
    switch in the UI, but that can be disabled to prevent any accidents.

    ...manages auto-feeding too, but that's not any where near complete yet.
