Control and features12

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 [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)Watering by time or by volume, single or cyclic. Volume watering is not available with every gateway (not with first-generation ZBBridge, ZHA or Alexa) [2]
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.	2–39Below 2 L/min the valve treats it as no water and closes after 30 minutes [1]
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.	Not stated by the manufacturer
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.	Not stated by the manufacturer
Alerts — what it means Which situations the valve reports in the app. No-water and leak alerts usually rely on flow meter data.	No water / low flow, leak (abnormal flow)A low-battery alert is not listed for this model in the maker's comparison table [4]
Child lock — what it means Locks the on-device buttons so a child cannot change the mode or switch the unit off.	No [4]
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 [3]
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 [2]
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 [3]
Watering history	Water usage and watering duration for up to 180 days, by day, week or monthHistory is available with ZBBridge-P/-U, NSPanel Pro, iHost and in Home Assistant; not with first-generation ZBBridge or Alexa [1]
Auto shut-off on no water	Below 2 L/min the valve reports 'No Water' and closes after 30 minutes [1]

Connectivity and compatibility7

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 requiredZigbee 3.0 only, no Bluetooth: needs a Zigbee gateway or coordinator (SONOFF ZBBridge-P/-U, NSPanel Pro, iHost, ZBDongle-P/-E, Echo with Zigbee). Philips Hue, IKEA and FRITZ!Box gateways are not supported [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.	ZigbeeZigbee 3.0 [3]
Wireless range — what it means The stated radio range, usually in open space. Walls and floors cut it noticeably.	130 mOpen space [3]
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 (ZBDongle-P/-E): all functions in Zigbee2MQTT; ZHA lacks volume watering [1]
App — what it means The maker’s app used to set up and control the device.	eWeLink [3]
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.	EFR32MG22 [3]
Zigbee role	End device (does not relay the signal) [4]

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-BSP version: BSP thread G3/4-14, 3/4" nominal size. The US version SWV-NH 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.	PlasticEngineering plastic [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 [3]
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 [3]
Housing material	PC + ABS [3]
Certifications — what it means Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).	CE, FCC, ISED [3]
Weight — what it means The device’s weight without packaging, per the maker.	278 g [3]

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) [3]
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 months1 year per the maker's comparison table [4]
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) [3]
Power source — what it means Where the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery.	Batteries [3]
