SAIC-iSmart-API/saic-python-mqtt-gateway 0.12.0 on GitHub

What's Changed

Add --saic-user-timezone / SAIC_USER_TIMEZONE config option to force the account timezone instead of relying on the SAIC API value. Useful when the API reports a wrong DST offset (#444). Discrepancies between the forced zone and the API value are detected by comparing the current UTC offset and logged at WARNING level.
Add SoC kWh fallback for vehicles that do not report realtimePower: the gateway now estimates energy consumed from the SoC delta and battery capacity so the kWh sensors remain populated even without live power data (#448).
Add battery capacity support for MG4 Urban (AH4EM series) (#455).
Default MG4 Urban non-Long-Range variants to 54 kWh when no custom override is configured (#452).
Home Assistant SoC icon now dynamically reflects the charging state (charging / discharging / idle) (#458).

Persist user-set HA gateway entities across gateway restarts by retaining their /set commands on the MQTT broker (refresh mode, all four refresh periods, and total battery capacity). On reconnect the existing command-dispatch path replays the retained value before configure_missing() would apply config defaults. A retained one-shot refresh mode (force, charging_detection) is dropped on replay so a single-shot poll does not fire on every restart.

Note: on first upgrade only entities you change after the upgrade become persistent. Existing retained STATE values on the broker are not converted into retained /set commands. (#441)
Forward the retain flag through all typed publish methods so that retained state is correctly preserved on the broker across reconnects (#443).
Republish the effective Total Battery Capacity to its state topic right after the user updates the HA number. The handler used to only mutate the in-memory override and rely on the next vehicle poll to refresh the shared sensor topic, leaving the HA sensor stuck on the previous value. A payload of 0 re-publishes the per-model default (#445).
