Sonoff SWV - cyclic_timed_irrigation Not Working on Some Devices

[mathmaniac43]

Hello! I have six Sonoff SWV devices. I have had some intermittent connectivity issues, one of which caused a few extra hours of irrigation, so when I found out that the cyclic_timed_irrigation capability had the ability to automatically shut off the valve after a period of time, I adjusted my Home Assistant automation to use that. (for now I can detect when the valve fails to open and notify myself; that is not as bad as flooding!)

Here's the weird part; I can see that my Home Assistant script triggers and modifies the state of each device in MQTT as expected, but only two of my six valves actually open and close for the configured period of time! The others appear to immediately increment the cyclic_timed_irrigation:current_count value from 0 to 1 without opening the valve and waiting for the configured period of time. I can manually open and close all of the valves through HA/Z2M, just trying to trigger via cyclic_timed_irrigation does not work for some of the valves.

I am wondering if anybody has any ideas for what I could do to diagnose or attempt to fix. I have popped out the batteries from them for a few seconds, and think my next step would be to try and re-pair to Z2M (which would be annoying but is fine). I am down to factory reset each device or anything I need to if they start behaving consistently. All devices are on the latest firmware (version 4100).

Thanks for the help!

PS - Here is my HA script, which I call from an automation.

sequence:
  - action: mqtt.publish
    metadata: {}
    data:
      payload: |-
        {
          "cyclic_timed_irrigation": {
            "current_count": 0,
            "total_number": 1,
            "irrigation_duration": {{ valve_on_time_seconds }},
            "irrigation_interval": 0
          }
        }
