• The page opens on live data. The web host disconnected Dieter's core from the gateway and the daemon two
  minutes after the last tab was hidden, and Home Assistant loads the panel's frame afresh each time it is opened, so
  almost every open reconnected from scratch first (session, machines, devices, then the machine streams): 2–5 s on
  "connecting" or on old data after the page itself had started in under a second. The core now connects when the
  add-on starts and stays connected. With the embedded gateway (the default) the gateway and the daemon are on the
  same machine, so this costs next to nothing; with an external gateway it is one more device that stays online.
  • The web host's DIETER_WEB_HOST_IDLE_MS (milliseconds, not an add-on option) still sets a grace instead.
  • The log says how long connecting took (core connecting (took … ms)).
