pyHottop gives you the power to control your Hottop KN-8828b-2k+ roaster directly through python code. **This library is meant to be used within applications and should not be used by itself to conduct a roast**. Questions, comments or for support needs, please use the issues_ page on Github.

Getting Started
---------------

In order to interact with your Hottop roaster, you need to ensure your model has a USB-serial port which comes standard with the KN-8828b-2k+.

1. Install the CP210x USB driver to read from the serial port:

https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

2. Install the pyHotop module:

``pip install pyhottop`` or ``python setup.py install``

3. Plug your Hottop roaster into your laptop.
4. Test connectivity to the roaster by running the diagnostic utility:

``pyhottop-test test``


Features
--------

This library provides full control of the Hottop roaster. Built-in callback functionality allows you to build applications that decouple the processing logic from the library from the core of your application.

* Stream Hottop readings
    * Easy-to-use callbacks that return readings
    * Adjustable polling interval
    * Human-readable settings
    * Flexible collection of data
    * Debugging interface
* Control the Hottop directly
    * Heater settings
    * Fan speeds
    * Drum motor toggle
    * Cooling motor toggle
    * Solenoid (drum door) toggle
    * Chaff tray (detection) reader
* Auto-discover roaster connection
    * Loops over USB connections to find the proper serial
