I love HA, after setting it up I used an old tablet as the dashboard to control and monitor the house, plus the app. It’s very easy to setup and work with, maybe a bit convoluted in the initial setup but once done, you barely do anything until you add new sensor. You can setup a whole SCADA-like system with it, controlling your garden, power grid/solar and monitoring it, integrating CCTV and all, and it’s free. A similar industrial project I did before, SCADA and RTUs that monitored and controlled many actuators and solenoid valves and sensors, cost wise was ~$9M, and all the functionalities were implemented can be done with HA on principle.
Ten years ago a lot of this would have required expensive proprietary systems or a lot of custom engineering
Pretty much yeah, that SCADA system was in 2012 and the complexity was off the charts: electric panels, Allen Bradley expensive hardware and software, ladder/C#/MSSQL/historianDB/etc tech stack, modbus/profibus/hart protocols, it is a nightmare to maintain, even editing the HMI was a process by itself. If that project would be done now, probably won’t cost 25% of the original cost.
