If `app_token` is empty, direct dashboard/API access is disabled. History → Custom Charts → Copy link creates a random persisted share token and returns a chart-only URL.

+- Persists chart shares behind random bearer URLs whose token is stored only as a hash; shared URLs do not expose metric/device selectors.
+- In Supervisor mode, requires `app_token` for direct dashboard/API/WebSocket access on port `8787`, while trusted HA ingress remains automatic.
+- Keeps only generated Custom Chart data public to the network; the add-on watchdog may call `/api/health` anonymously only from the Supervisor peer.
 - Makes the Home Assistant entity picker in `Reusable data -> Shared Flow input` explicit with a separate search box and selected `entity_id` field.
 - Filters the live Home Assistant entity catalog by friendly name, `entity_id`, current state, unit and device class while typing.
 - Keeps automatic Supervisor authentication, failed-test manual fallback and standalone Home Assistant behavior unchanged.

+Usługa słucha na TCP `8787`; ingress Home Assistant przekazuje Web UI na ten port. Gdy wykryty jest `SUPERVISOR_TOKEN`, bezpośredni dashboard/API na `:8787` wymaga `app_token`; przy pustym `app_token` bezpośredni dashboard jest zablokowany. Z sieci bez poświadczeń dostępny jest tylko publiczny widok i endpoint danych pojedynczego Custom Chart (`/charts/custom/<share-token>`, `/api/public/charts/custom/<share-token>`). Token udostępnienia jest losowy, jego skrót jest zapisywany w SQLite, a sam URL nie zawiera nazw urządzeń ani listy metryk. Link kopiowany z History → Custom chart omija HA ingress i wskazuje bezpośrednio host/IP dodatku na jego porcie HTTP (domyślnie `8787`). `/api/health` bez tokenu jest akceptowane tylko od peera Supervisora na potrzeby watchdoga; bezpośrednie żądanie sieciowe wymaga `app_token`. Baza jest zapisywana w `/data/gree-controller.db`; konfiguracja używa `backup: cold`, więc dane są objęte backupem dodatku.

 Watchdog sprawdza `/api/health`. Do diagnostyki sieci najpierw sprawdź `ha network info`, poprawność `gree_interface`, broadcast konkretnej podsieci i reguły UDP/firewalla.

 ### Access, data and security

-The service listens on TCP `8787`; Home Assistant ingress proxies the Web UI to that port. If `8787` is reachable from an untrusted network, configure `app_token` or block the port at the firewall. The database is stored in `/data/gree-controller.db`; `backup: cold` keeps it in the add-on backup.
+The service listens on TCP `8787`; Home Assistant ingress proxies the Web UI to that port. When `SUPERVISOR_TOKEN` is detected, direct dashboard/API access on `:8787` requires `app_token`; with an empty `app_token`, direct dashboard access is disabled. From the network, the only unauthenticated application data is the single public Custom Chart view/data endpoint (`/charts/custom/<share-token>`, `/api/public/charts/custom/<share-token>`). The share token is random, only its hash is stored in SQLite, and the URL does not expose device names or metric selectors. Links copied from History → Custom chart bypass HA ingress and point directly to the add-on host/IP on its HTTP port (default `8787`). `/api/health` is accepted without a token only from the Supervisor peer for the add-on watchdog; direct network requests require `app_token`. The database is stored in `/data/gree-controller.db`; `backup: cold` keeps it in the add-on backup.

 The watchdog checks `/api/health`. For network troubleshooting, verify `ha network info`, `gree_interface`, the selected subnet broadcast, and UDP/firewall rules first.
