I've found openHAB to be quite stable. Setup is pretty heavyweight but I've just had it chugging along happily managing BLE, Z-Wave, a few cameras, etc.
Ditto. Even across upgrades it’s had very, very few issues - and I’m using it for both a bevy of normal home automation stuff, and to manage isolated power and water microgrids for several homesteads - routing power, switching dump loads on and off, balancing battery banks, monitoring tank levels, running pumps, alerting on low flow states (time to change a filter), and all the rest. It’s mission critical for us, and hasn’t let us down in the two years it’s been running the show.
