Sonoff SWV water valve reporting its status to z3m

Hardware
1

Hi everyone,

I’m experiencing an issue with my Sonoff Smart Water Valve and Zigbee2MQTT (z2m) integration in Home Assistant.

When I manually operate the valve using its physical button (to turn it on or off), the device doesn’t automatically report its new state to z2m. This results in Home Assistant displaying an incorrect, outdated status for the valve. However, I want to clarify that controlling the valve (turning it on or off) directly from Home Assistant works perfectly, and its state updates as expected in that scenario.

Interestingly, the valve does report its state correctly for other changes, such as when water flow is detected or stops. The problem seems specific to manual on/off actions via the device’s button.

Has anyone else encountered this with their Sonoff Smart Water Valve? How does your valve behave in this scenario? Any insights or potential solutions would be greatly appreciated!

My setup is the same as yours, i.e. the SWV ans Z2M:

Firmware build date  20240820
Firmware version        1.0.4
Manufacturer         SONOFF
Model                SWV

The dashboard reflects manually switching the valve on and off almost instantly.

Sorry, that I can’t provide more insight for you to resolve your issue :frowning:

Thank you for confirming it is expected behaviour :wink:

They’re telling you that it is not expected behaviour.

I don’t have the SWV so can’t help you much, but it could probably be fixed in Z2M by checking the Reporting tab of the device.

Try checking if setting reporting for OnOff cluster on endpoint 1 fixes your issue. Maybe @chairstacker can confirm what his reporting tab looks like.

The below is from a different device, but this is the screen you’re looking for

Thank you for the clarification! Yes i meant that “expected behavior” was indeed what I had expected, i.e. sending status even though the change happened by pushing the device button.

I actually reinterviewed the device and now the status is correctly reported, so problem solved! I didn’t know about the page you suggested looking, so thank you for the tip!

However I have some issues with the measure “flow” and others. Until yesterday flow was reported then suddenly it stopped at 7.20pm. before interviewing, it was just not present at all in the UI of z2m: next to the measure in the Expose menu, there was no number nor icon. Now I see it there but it’s as “null”. In the Logs I see the JSON file that is reported as containing “null” for several measures. However, Battery is correctly reported.

Do you know how this could be fixed?

Thanks.

Sorry, like I said earlier, I don’t own that device. Hopefully someone else can help with that.

There’s a few threads here about the swv device. Maybe you could try searching for them in the meantime, in case anyone had your same issue.

Same here - I ordered 2, the first one works as expected, but my second one has the same issue as you describe. I have tried deleting it and re-interviewing it to no success. Going to keep trying, and might write to support.

Interesting observation - I think it might be z2m not syncing the state properly. If i click the manual button, then sync, the state updates. Otherwise it goes to the de-synced state. After re-configuring the device, it works like normal - strange.
