The stuff i use for my simple home automation and power monitoring
is a backup from some folders of the pi is use for home automation
Contains a c++ client i wrote that moves p1 and modbus data to mqqt (very messy but small and simple, works on my machine)
It depends on mosquitto (and libs and client) and libmodbus being installed on the pi
is a backup of my website containing a small (and also messy) mobile client (index.html) for controlling the lights and power monitoring (also some other projets html for the christmass tree)
