- Around line 163-171: Update the maintenance_control OFF handler to stop and
execute decide_sleep only when maintenance_active is true; otherwise, restart
prepare_cycle only if script.is_running: prepare_cycle, ignoring retained OFF
echoes after admission has completed. Add coverage for rejection and
exit_maintenance echoes, verifying a single acquisition and preservation of
REJECTED_LOW_BATTERY.

Behavior
Retained mode changes could leave older asynchronous work running. Maintenance OFF during battery/time admission could sleep without fresh plant readings. Storage changes during an unfinished refresh could publish stale state or leave acquisition running. A repeated Maintenance ON or a successful OTA could also let the old watchdog start an unwanted refresh.
Cancel the previous cycle's child scripts when a new command starts preparation. Handle OFF before Maintenance becomes active. Cancel the old watchdog before renewal and successful OTA cleanup. Reject infinite battery readings at the Maintenance admission boundary. Ignore echoed Maintenance OFF after rejection or exit, and ignore Storage commands whose desired state is unchanged. This preserves the rejection result and avoids duplicate acquisition cycles.
Verification
python3 -B -m unittest discover -s tests -v; pinned ESPHome Python runstest_api_boot.pyseparately.0x6a9cb288, and synthetic credentials, broker, local fonts and label. No live device, shared builder or fleet test is used.AI assistance
Codex assisted implementation and verification. Source changes are limited to the MQTT profile. The author checked the semantic diff, test execution and full firmware compilation.
