Sonoff Hydro DUO: Capabilities And Limitations
Based on listed specifications, not hands-on testing. Manufacturer sources are linked where checked.
What it offers
Water-consumption monitoring is listed as an additional usage feature. Check the measurement method, units and history available. Built-in flow meter reading 2 to 45 L/min, which the valve uses for volume-based watering and per-zone usage tracking.
View Water Consumption Monitoring details →A Home Assistant integration is listed, providing an integration path to verify for the exact model. Check the exact integration and firmware. A catalog integration label does not establish local control, official support or available entities. SONOFF documents the Hydro DUO on Home Assistant through both Zigbee2MQTT and ZHA, listing which features each exposes. ZHA additionally needs the Hydro_DUO_ZHA_Script SONOFF publishes.

What to consider
Apple Home support is listed as unavailable; do not assume the device appears directly in Apple Home. SONOFF's Matter bridge device list covers the Hydro valves (SWV-NH and SWV-BSP) but states they are supported only in Google Home, because Apple Home does not implement the water valve device type. Apple Home has no Zigbee radio either, so there is no other route.

Yes, according to the listed specifications. Check the measurement method, units and history available. Built-in flow meter reading 2 to 45 L/min, which the valve uses for volume-based watering and per-zone usage tracking.
View Water Consumption Monitoring specifications →Does Sonoff Hydro DUO support Matter?
Matter is listed as “SONOFF Hub required”. The stated condition applies to this feature. Verify the exact device type, firmware and features exposed in your chosen platform. Matter support is not proof of feature parity. The valve is not a Matter device itself: it is Zigbee 3.0 only. SONOFF lists the Hydro valves (SWV-NH, SWV-BSP) among the models its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) republish to Matter, exposing valve configuration and control plus flow measurement.
