The Sonoff SWV-BSP is a Zigbee3.0 garden valve with a Silabs EFR32MG22 Zigbee radio and built-in flow/volume sensing; it pairs with Zigbee2MQTT/Home Assistant, supports time‑ or volume‑based schedules, and reports leak/no‑flow states. Good for DIY Zigbee smart gardens thanks to brass fittings, a flow sensor (≈5–10% reported accuracy) and water‑volume scheduling, but expect AA battery operation, slow/approximate battery reporting, and some firmware/features that depend on Sonoff firmware or gateway.
Buy if you want a Zigbee‑native irrigation valve with flow/volume scheduling for Home Assistant; avoid if you need mains power or precise lab‑grade flow metering.
