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+.
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
Install the pyHotop module:
pip install pyhottop or python setup.py install
Plug your Hottop roaster into your laptop.
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
