about

nx_home.nx -- SOVEREIGN home-control server (H0 of the IoT workstream). The brain a control surface (Roku "Home" tab / web / phone) POSTs to; it holds the device registry + live state and applies commands. H0 uses a SIM driver (a command just updates state) -- real IP-hub drivers (Matter/Hue/MQTT) plug in behind this later. Sovereign socket HTTP server (no python/shell). REST: GET /home/state -> {"devices":[{id,name,room,type,on,brightness},...]} POST /home/cmd?id=<id>&on=<0|1>&bri=<0-100> -> the device's new state (404 if unknown id, 400 if no id) POST /home/shutdown -> {"ok":1} then the server exits (managed teardown; auth-gate in prod) Idempotent (#10), structured errors (#6), graceful (#14). Devices embedded for H0; H1 makes them data-driven (#11, TSV/seg_store) + persisted. license_tier: ORIGINAL nx_home <port>
