Recursively watch a directory for modifications and publish file content to an MQTT broker
mqtt-watchdir is a Python program by Jan-Piet Mens to watch a directory and
publish new or modified files in that directory hierarchy to an MQTT broker,
using a matching topic. Source and instructions are available at
https://github.com/jpmens/mqtt-watchdir and it is also available via pypi.
It is a similar idea to my mqttfs fuse filesystem, but ultimately implemented in a better (and portable) manner.
