EXTENSIONS

Observability and safe operational control for a TP-Link Omada controller. One fan-out sync reads every site, device, client, switch port, gateway WAN and SSID into addressable resources, and writes a drift record comparing configuration — not telemetry — against the previous sync, so an idle network reports nothing and a firmware bump, a re-addressed WAN, a disabled PoE port or a device that stopped answering each report themselves. Talks the supported Open API in client-credentials mode, with the controller's own web API as an optional fallback for reads the Open API does not expose. Writes are limited to reversible operational actions — reboot, PoE, client block, reconnect, LED, locate, firmware — each fanning out over a list in one controller session.
