Sonoff SWV water valve - auto-turn-off

Configuration Zigbee
,
62

ok thanks.
I just installed Home Assitant and added the device. Now how can I update its firmware ?

63

Confirmed, once the OTA settings in configuration.yaml are done, this device does need the extra things set using ZHA toolkit for ZHA to pick up the firmware

64

I can confirm that MaikaiLife Shaunā€™s method works correctly on Home Assistant 2025.12.3 after installing the ZHA Toolkit integration through HACS.

Just did the update config as mentioned above and after a restart of HA the update was already listed. The extra step with ZHA toolkit seems not to be required any more with 2026.4.2.

Hi there,

Does anyone know if itā€™s possible to configure the ā€œInchingā€ setting to automatically close the valve after xyz time?

Iā€™m using the zha integration in home assistant, with the latest firmware version. In the UI ā€¦ I only see the ā€œWater shortage auto-closeā€ switch. As it seems from this post (submittion) ā€¦ the Zigbee2Mqtt has by far more options ā€¦ but Iā€™m wondering if we can send a command via the developer tools, like the one for updating the firmware to setup the inching mode and make the device to switch off on its own.

PS: I have a sonoff USB stick connected to home assistant, so I think canā€™t use the sonoff app to configure the valve unfortunatelly.

I can't seem to get the valve to turn on using this script, can anyone take a peek at it and let me know if there's an obvious reason why the script doesn't work? I can trigger the valve from HA directly, and it is set up with Zigbee2MQTT.

My 5 min timer script for the Sonof is as follows

action: mqtt.publish
data:
  evaluate_payload: false
  qos: 0
  topic: zigbee2mqtt/Sonoff SWV/set
  payload: "{\"state\" : \"ON\", \"on_time\": 300}"

As I read it, the "irrigation_duration" setting is the time used for scheduled irrigation (automatic daily from within the Sonoff device /app itself)

I don't own one, but I think that's your problem. If the current_count = total_number, it means the max number of cycles has been reached so it won't run. Try setting "current_count": 0 instead (or leave as is and set "total_number": 2)

I figured it out by watching the Z2MQTT log... I had the wrong entity ID for the SWV. I must have renamed it at somepoing... really dumb on my part. It seems to work regardless of whether the current_count was set to 0 or 1... I haven't tested to see if setting it to 0 effectively makes it run twice... I will test that and update this later.
