- Issue 6 (2-3s toggle lag): the command service now writes the expected state
immediately for ALL devices (not just demo). The card flips within the
Livewire round-trip; the real MQTT echo / post-command HTTP poll reconciles it
(monotonic — newer observed_at wins). Toggling now feels instant.
- Issue 7 (wrong icon): Device::displayIcon() with a per-device override
(config.icon) + a picker on the device page (lamp/led/plug/window/door/
doorbell/sensor/…); cards use it. New icons added.
- Issue 8 (dead "Update prüfen"): real Shelly.CheckForUpdate over HTTP now
reports available version / up-to-date / unsupported instead of a demo string.
- Issue 9 (no MQTT option): device page can switch a Shelly between Local (HTTP,
probed) and MQTT transport; driverFor already routes by protocol.
Suite 71 green, 12/12 tabs clean.
