I recently moved into a new house where I went all in with automating and measuring everything. Every single door and window has a sensor. Every single appliance: switch, light, TV, computer and devices like wasmachines, garage doors, heatpumps, invertors, ovens, air filters is made smart and connected to my home assistant. I never ever saw the ui of home assistant. Everything is done with Claude and it works absolutely perfect. It would be a fulltime job to figure everything out manually. Also many devices like our heating floor manifold do not come with a build in Ethernet or wifi connector. I extensively used AI to connect an esp directly to its board. Once you got the Rx and tx working, Claude can reverse engineer the data streams and build a driver/integration for home assistant. AI is really super awesome here. Zero need for Cloud based crap like Tuya or smart devices requiring a cloud service account.
