Seconding this. I was able to just run it with docker compose on a cheap mini PC and it chugs away happily, interfacing with all manner of devices (Phillips/Lifx/IKEA/Airpurifier/Bunnings brands). Only gets tricky to set up devices when you're dealing with some hostile cloud based gadget that doesn't want to play nice.
Unbelievable it can all be controlled offline using Siri on an iPhone, or other voice assistants.
It can even display your electricity consumption by counting the LED pulses on your smart electricity meter that fires every 1000th of a kw/h, only takes a cheap ESP32 and a photodiode: https://github.com/klaasnicolaas/home-assistant-glow
Such a wonderful project.
