Control and features13

Built-in flow meter — what it means A flow meter counts how much water passes through the valve. With it you can water a set number of litres and see usage statistics; without it watering is set by time only.	YesThe maker recommends vertical installation; horizontal mounting increases flow measurement error. The flow meter reduces water pressure by about 10% [1]
Watering modes — what it means How a single watering run is set: manually, by duration (minutes) or by water volume (litres). Cyclic mode repeats watering several times with pauses so the water can soak in.	Manual, by duration, by volume, cyclic (with pauses)For volume watering a time limit can be set: if the volume is not reached, watering stops [1]
Flow measuring range, L/min — what it means Range within which the flow meter counts water, in litres per minute. Below the lower limit the volume is not counted and the valve may report no water.	2–45If flow stays below 5 L/min for a set time, the valve reports water shortage and can close [3]
Number of schedules — what it means How many independent watering schedules can be stored in the valve — for example morning and evening, or different weekdays.	6 [3]
Schedule options — what it means Which watering rules can be set in the app. Weather-based skip cancels watering in unsuitable forecast conditions; seasonal adjustment changes watering duration or volume over the year.	Selected weekdays, odd / even days, every N days, weather-based skip, seasonal adjustmentInterval of 1 to 30 days. Weather-based skip (rain probability, humidity and temperature thresholds, next 24 hours) works only in Zigbee mode via a gateway; manual rain delay is also available. Seasonal adjustment is a monthly multiplier of duration and volume [3]
Alerts — what it means Which situations the valve reports in the app. No-water and leak alerts usually rely on flow meter data.	Low battery, no water / low flow, leak (abnormal flow), frost riskWater shortage: flow below 5 L/min for a set time (valve can be set to close); leak: flow detected a set time after closing; frost: based on forecast minimum temperature [3]
Child lock — what it means Locks the on-device buttons so a child cannot change the mode or switch the unit off.	YesDisables the button on the housing; app control still works [1]
Operating water pressure — what it means Mains water pressure at which the maker guarantees correct operation. 100 kPa ≈ 1 bar.	60–800 kPaDocumented as 0.06–0.8 MPa [1]
Water temperature — what it means Permitted temperature of the water passing through the valve. Irrigation valves are designed for cold mains water.	5–40 °C [1]
Zones (outlets) — what it means How many separate watering lines the valve controls independently. With one zone, two areas on different schedules need two valves.	1One inlet and one outlet [1]
Watering history	Water volume and duration by day, month and half-year, exportable [3]
Schedules stored on the valve	YesSchedules run even without a network [3]
Time limit for volume watering	YesIf the set volume is not reached within the user-set time limit, watering stops automatically [2]

Connectivity and compatibility9

Hub required — what it means Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.	Hub optionalWithout a hub the valve connects to a phone over Bluetooth (eWeLink Proximity mode): manual watering, schedules and basic settings are available near the valve. Remote access, scenes and push notifications need a Zigbee gateway; weather-based skip works in Zigbee mode only [1]
Connectivity — what it means The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.	Zigbee, Bluetooth LEZigbee 3.0 and Bluetooth LE [2]
Wireless range — what it means The stated radio range, usually in open space. Walls and floors cut it noticeably.	130 mOpen space [1]
Home Assistant — what it means How the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration.	Via hub / coordinatorThrough a Zigbee coordinator: Zigbee2MQTT or ZHA (for ZHA the maker currently supplies a separate script). Available features depend on the platform; see the maker's compatibility table [2]
App — what it means The maker’s app used to set up and control the device.	eWeLink [1]
Processor / radio chip — what it means The microcontroller or radio module inside, per the maker (for example ESP32). For firmware such as WLED and ESPHome it determines available features and whether the device can be re-flashed.	TLSR8656 [1]
Radio frequencies and transmit power	Zigbee 2405–2480 MHz, ≤10 dBm; BLE 2402–2480 MHz, ≤10 dBmFrom the CE statement for the EU version [1]
Zigbee role	End device (does not relay the signal) [5]
Matter support — what it means Whether the device supports the Matter standard, directly or through a bridge. Matter lets you add it to Apple Home, Google Home, Alexa and Home Assistant.	Via a bridgeInto Apple Home through a Matter bridge: ZBBridge-U, iHost or eWeLink CUBE with a SONOFF Zigbee dongle [2]

Housing and installation7

Connection thread — what it means Thread on the valve inlet and outlet. G (BSP) is the European garden tap standard, NH is the American one; they are not compatible without an adapter.	G 3/4" (BSP)SWV-ZFE version: BSP thread G3/4-14, 3/4" nominal size. The US version SWV-ZFU has an NH3/4-11.5 thread and does not fit European taps without an adapter [1]
Inlet material — what it means What the threaded part screwed onto the tap is made of. The material affects how the joint holds up under constant water pressure and in the sun.	Brass [4]
Ingress protection (IP) — what it means Protection against dust (first digit) and water (second). IP20 is for dry rooms only, IP44 resists splashes, IP65 and up handle water jets and outdoor use.	IP55 [1]
Dimensions — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	152 × 100 × 46 mm [1]
Housing material	PC + ABS [1]
Certifications — what it means Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).	CE, RoHS, FCCSWV-ZFE (EU version). The manual lists CE/RoHS; the maker's help centre and comparison table list CE/RoHS/FCC [1]
Inlet filter screen	Yes [4]

Power4

Batteries or battery — what it means Which cells it takes and how many. A built-in rechargeable battery is stated in the value.	4 × AA (1.5 V) [1]
Battery life — what it means Typical life on one set of batteries or one charge, per the maker. Frequent triggers, cold and a weak signal shorten it.	12 monthsAbout 1 year with two 30-minute waterings per day; about 1 month if used continuously as a water meter [3]
Supply voltage — what it means The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.	6 V ⎓ (4 × 1.5 V AA) [1]
Power source — what it means Where the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery.	Batteries [1]
