Ubiquiti

Reads device and client stats from a local UniFi Network controller - add it by address and your controller login, authenticated the same way the UniFi web UI itself logs in (session cookie, self-signed certificate accepted).

What it reports

Every adopted device on the controller gets an online/offline sensor and a connected-client-count sensor, plus a restart button - the one write action this integration offers. There's no port or SSID reconfiguration; this is a monitoring-and-restart integration, not a full network-management replacement for the UniFi controller itself.

Works with Dashboard cards, History, and Automations exactly like every other integration - useful for a "notify me if my access point drops offline" automation, for example.
