Easy automation with MQTT and/or openHAB
HABApp is a asyncio/multithread application that connects to an openhab instance and/or a MQTT broker. It is possible to create rules that listen to events from these instances and then react accordingly.
The goal of this application is to provide a simple way to create home automation rules in python. With full syntax highlighting and descriptive names it should almost never be required to look something up in the documentation
The documentation can be found at here
