Same. I've been a huge Home Assistant fan and minor contributor for many years. My house is among the smartest houses I've ever heard of. HVAC control, security system, air quality monitoring, multi-site IT systems monitoring, lighting controls (including LED strips that update to the right color scheme for the next holiday), whole-house networked audio (including streaming off-site if connected to the VPN), on and on. All self-hosted, on-prem, zero cloud, coordinated by Home Assistant. Offsite notifications via email, offsite control and monitoring via my Openwrt router's VPN server.
