The device pushes button events to the backend via its Input Link URL feature;
the backend decides. No polling — the chosen entry architecture.
packages/devices:
- dingtian driver: configureInputPush() writes the device's input_link_url
config (per-input server/port/path, en=1, active-LOW, plain HTTP) so each
input HTTP-GETs the backend on press/release. Extracted #readConfig/#writeConfig
(with the required command:setconfig injection + post-write reset tolerance).
apps/server:
- routes/devices.ts: public GET/POST
/api/devices/dingtian/:deviceId/input/:n/{on,off} — translates a device push
into an internal device event. Not behind cookie/CSRF (machine call from the
device); trust comes from the signed event log, not this request.
- device-events.ts: internal EventEmitter bus so the entry flow subscribes to
input events without coupling to HTTP. Wired into the server.
Verified on hardware: configured the device, then real presses on all 4 inputs
pushed to the backend (input N on+off, source = device IP). No polling.
wiki: device-input-flow concept (path + trust model for the flat/no-VLAN
network); dingtian-relay updated; index + log.
