CA 06:44 PM ATM environment alarm system atm-environment-alarm-system #61: MQTT telemetry to boeghpoulsen.dk via DTUdevice hop

Update from continued discussion:
* Publishing will be a continuous stream (not batched at boot+midnight), enabled by the network-simplification design in #63 - DTUdevice becomes the PS's persistent default connection rather than a sche... claude assistant

CA 06:36 PM ATM environment alarm system atm-environment-alarm-system #63 (New): Drop app-based Wi-Fi provisioning; hardcode DTUdevice; reset-button-hold for local OTA

Simplification agreed during MQTT architecture discussion with Claude: the current app-based Wi-Fi provisioning flow (wifi_prov_mgr, SoftAP + ESPSoftAPProv app + QR code) can be dropped entirely.
Proposed replacement:
* STA network i... claude assistant

CA 06:35 PM ATM environment alarm system atm-environment-alarm-system #62 (New): Frequency ramp-up + max-value capture during warning/alarm

Original wishlist item from the start of this project's Claude session: "More frequent measurements (frequency configurable) when above warning level to reduce lag and improve fire alarm abatement" plus "when more frequent measurements, ... claude assistant

CA 12:59 PM ATM environment alarm system atm-environment-alarm-system #61 (New): MQTT telemetry to boeghpoulsen.dk via DTUdevice hop

## Architecture sketch discussed with Claude (not yet implemented):
* PS continues to store measurements locally as today (LittleFS ring buffer), unchanged.
* At the existing DTU hop (power-up + local midnight, see #58), in addition ... claude assistant

CA 12:26 PM ATM environment alarm system atm-environment-alarm-system #58: Access to DTUdevice

Landed the correct design: dtu_sync_task()/dtu_time_sync() in wifi_manager.c briefly connect to DTUdevice at power-up and at local midnight, purely to force an NTP sync (esp_netif_sntp_sync_wait()), then restore whatever network the PS w... claude assistant

CA 10:46 AM ATM environment alarm system atm-environment-alarm-system #58: Access to DTUdevice

Correction: the DTU auto-join follow-up noted earlier (commits 51f16fc, 80fe8b8, c7e4ae3, cbd7077) has been reverted from master. The premise was wrong - DTUdevice blocks inbound internet access, and on reflection the real network in use... claude assistant

CA 02:06 PM ATM environment alarm system atm-environment-alarm-system #58: Access to DTUdevice

Follow-up: added automatic connection to DTUdevice during provisioning mode (before this, the device only used DTUdevice if already provisioned with it manually). wifi_manager.c now scans for DTUdevice (SSID/password configurable via Kco... claude assistant

CA 01:51 PM ATM environment alarm system atm-environment-alarm-system #17 (Ongoing): Watchdog signal

Implemented: new watchdog_mon module. (1) Crash-loop: boot-time check of esp_reset_reason() + an NVS-persisted counter; 3 abnormal resets in a row asserts fail-safe outputs (all lamps on, sounder quiet, CC on) and halts before retrying t... claude assistant
