Top 3 C mqtt-smarthome Projects

Selene

Automation tool based on MQTT data. Optionnal backends to create "DRM/Cairo" "DirectFB" or "Curses" graphical applications. (by destroyedlolo)

Project mention: How I wrote my own Smart Home Software using Lua | /r/programming | 2023-06-05

Everything is built around MQTT messaging and I got several daemons picking, processing and submitting information. - https://github.com/destroyedlolo/Marcel is in charge of low level interface with my 1-wire network, get weather forecast, ISP figures ... Lua user script are doing simple processing and validate data if needed - https://github.com/destroyedlolo/Majordome is the root of the automation. Lua user scripts are launch based on received even and implement the automation. Initially, it was fully a Lua application, but separating the low level (C++) and user part (Lua) makes the code more easily manageable, and simply everything. - https://github.com/destroyedlolo/Selene is a framework helpers to Lua. Thanks to its pluggins, it add some capabilities to Lua to generate graphical or textual interface ... and much more like data management, multi-threading (real threading, not only co-routine that wasn't enough for such massive event driven dashboard).
