SWV-ZF2 ends manual irrigation early but state_1 remains ON

What happened?

A SONOFF SWV-ZF2 was configured for a 21-minute manual irrigation.

The device accepted and reported:

• manual_irrigation_duration: 21
• manual_irrigation_mode: duration
• manual_fail_safe: 30

The irrigation started correctly and water consumption increased to 20 L during
approximately the first 5–6 minutes.

The device then reported the irrigation schedule as finished, but state_1
remained ON. Water consumption stopped increasing while the reported valve
state stayed ON.

An external Home Assistant safety automation finally sent OFF after 32 minutes.

What did you expect to happen?

The valve should irrigate for the configured 21 minutes and then:

• physically stop the irrigation;
• publish state_1: OFF;
• report a coherent actual end time and duration.

The 30-minute local fail-safe should also ensure the state returns to OFF.

How to reproduce it (minimal and precise)

1. Set manual_irrigation_mode to duration.
2. Set manual_irrigation_duration to 21.
3. Confirm that the device reports the value back as 21.
4. Turn channel 1 ON.
5. Observe irrigation_schedule_status_1, real_time_irrigation_duration_1,
   real_time_irrigation_volume and state_1.
6. The schedule may be reported as ended prematurely while state_1 remains ON.

Debug log

The original incident was recorded with the default info log level, so a full
debug log is not currently available. I can reproduce it with debug logging if
required, but reproduction operates a physical irrigation valve.

Relevant Zigbee2MQTT output from the incident is included below.

TimeoutOverflowWarning: 5184001000 does not fit into a 32-bit signed integer.
Timeout duration was set to 1.

Notes

Timeline:

• 23:03:54: irrigation started.
• 23:03:55: state_1 changed to ON.
• 23:05:02: 6 L.
• 23:06:01: 9 L.
• 23:07:02: 12 L.
• 23:08:03: 15 L.
• 23:09:03: 19 L.
• 23:10:04: 20 L.
• No further water consumption was reported.
• 23:35:55: an external safety automation sent OFF.

A later device payload simultaneously contained:

{
  "state_1": "ON",
  "manual_irrigation_duration": 21,
  "manual_irrigation_mode": "duration",
  "manual_fail_safe": 30,
  "real_time_irrigation_duration_1": 5,
  "real_time_irrigation_volume": 20,
  "irrigation_schedule_status_1": {
    "schedule_status": "end",
    "schedule_type": "manual",
    "irrigation_mode": "duration",
    "start_time": "2026-07-28T23:03:54+02:00",
    "expected_end_time": "2026-07-28T23:24:54+02:00",
    "actual_end_time": "2026-07-28T23:09:21+02:00",
    "actual_irrigation_amount": 20
  }
}

This is internally inconsistent: the schedule is marked as ended after about
5 minutes, while state_1 remains ON.

Zigbee2MQTT also repeatedly logged:

TimeoutOverflowWarning: 5184001000 does not fit into a 32-bit signed integer.
Timeout duration was set to 1.

No source file or test is named. Start by reproducing with debug logging and inspect the SWV-ZF2 irrigation schedule, state, and timeout handling around the reported TimeoutOverflowWarning. Done means a 21-minute manual run ends coherently with physical irrigation stopped, state_1 OFF, and consistent duration and end-time values.
