Could the « water flow » feature be added?
It’s the first one at the top left: SWV
From what I’ve seen regarding the flow rate, each manufacturer has its own name for this feature, unlike switches or other « simple » functions, for example.
On the development side, I don’t know if it’s possible, but it would be great to have a « group » where you can put all the names that will be given (I hope I’m being clear…).
I have a Sonoff SWV and here are all the states including the flow:
{
"auto_close_when_water_shortage": "ENABLE",
"battery": 48,
"current_device_status": "normal_state",
"daily_irrigation_volume": 12,
"flow": 0,
"irrigation_end_time": 1783243880,
"irrigation_start_time": 1783243462,
"last_seen": "2026-07-05T16:19:47+02:00",
"linkquality": 132,
"real_time_irrigation_duration": 600,
"real_time_irrigation_volume": 535,
"state": "OFF",
"update": {
"installed_version": 4100,
"latest_release_notes": null,
"latest_source": "https://raw.githubusercontent.com/Koenkk/zigbee-OTA/master/images/Sonoff/zbswv_v1.0.4.ota",
"latest_version": 4100,
"state": "idle"
}
}
On my side, I retrieve the real_time_irrigation_duration and real_time_irrigation_volume via a virtual MQTT device, but I wouldn’t say no to automatic retrieval either 
Does this type of device work well? What is the purpose of the feature below?
Works great for me for automatic watering of the vegetable garden and plants, and if I have water in my tanks, I activate the pump to avoid using the urban network (with a manual bypass for the tank<>urban).
This is the volume of water (in liters) that passes in real time: very practical for adding 300 liters to the pool and automatically stopping the valve
