Extension

This section serves as a launching point for adding support for new devices to PyHK. Note that program logic (acting on sensor values) should probably be implemented in pyhkfridge or via pyhkcmd.py, this section is for adding new data sources. Before attempting to extend PyHK, consider whether your goal can be accomplished with existing systems:

• PyHK can subscribe to messages from a MQTT broker. Many existing tools/systems work with MQTT already, and MQTT messages can be accepted from remote computers.

• (TODO) PyHK can watch for changes in simple text files, so writing a small independent script to periodically write data to a text file may be the easiest way to integrate new devices without working directly with PyHK source code.

(TODO) Document internal program structure
