Sinope Sedna Valve 2nd Gen 3/4 in (VA4220ZB)

Quick verdict

A serious automatic water shut-off: a full-port stainless ball valve that joins ZHA or Zigbee2MQTT directly and reports state, position and battery for local leak automations. It is mains-powered (with optional AAA or UPS backup), so site it near an outlet and lean on a nearby mains Zigbee router for mesh reliability. Don't confuse it with the Wi-Fi VA4220WF model - the Zigbee SKU has no native voice assistants, which is exactly what a local-first build wants.

Standout: A full-port stainless motorized water shut-off valve rated to 145 PSI that pairs to any Zigbee coordinator for fully local leak-shutoff - no Sinope hub.
