Privacy-first smart home setups — Privacy-conscious users self-host ioBroker to keep device data off manufacturer clouds while still using voice assistants and mobile dashboards.
Domoticz
DIY smart home automation — Hobbyists building custom home automation setups on Raspberry Pi or repurposed hardware without paying ongoing subscription fees.
