Sonoff Zigbee Smart Water Valve

Just received delivery of my Sonoff and paired it to HE.

Driver Version is: 1.3.6 2024/09/23 12:55 PM
Advanced Device Details/Data reports: softwareBuild: 1.0.2

Testing it next to the computer (ie not yet connected to water), and only connected to HE (no Homekit or other integration) I noticed the following:

  1. Current States Valve does not update to closed when closed via Preferences Auto Off Timer.
    Set the Auto Off Timer to 10 seconds, then clicked Open on HE Device details page. The valve clicks, indicating it has opened, and the Current States Valve changes to open. About 10 seconds later, that valve clicks again, indicating it closed, but there is no change to the Current States Valve field; it remains showing open. Irrigation start time, end time, irrigation duration and last open duration are all accurate. Clicking refresh in the device details commands section updates the valve status. It does not update the irrigation end time.

  2. After item 1, if I have not clicked refresh, but click Close on the HE device details page, there is no audible click of the valve because it is already closed, but the Valve Status updates to closed, and the irrigation end time updates to the time I clicked close. Irrigation duration and last open duration do not change.

  3. If, while the valve is closed and showing closed (after item 2 above) I manually open the valve by pressing the button on the valve (and hear the click indicating it opened), the irrigation start time updates to when I pressed the button on the valve, but nothing else changes - the valve Status does not update to open, AND the auto off timer does NOT work; the valve will remain open indefinitely, and AFTER the auto off timer duration has passed, the button on the valve starts double blinking green about every 2 seconds. In this state, both Save preferences and Refresh will update the valve status, but not invoke the Auto Off.

  4. When it is in the state of item 3 above, if I press the button on the valve, the valve audibly clicks indicating it is closed, the irrigation end time updates and the Last Valve open duration updates, but neither the valve status or the irrigation duration update. Save preferences updates only the valve status to closed; irrigation duration remains.

  5. Changing the Preferences Auto Off Timer to 0 and setting the duration in the Device Set Irrigation Timer field (the latter has a reference to Auto Off in the small print) does not work; as soon as I click Save Preferences, the Device Set Irrigation Timer field reverts to 0.

To deploy this device, I need an Auto Off Timer that works regardless of whether the valve is turned on via an automation, via clicking the on button on a HE dashboard or device details page, or manually via clicking the button on the valve itself. It appears this last requirement is what is currently not working.
