A summary of selected recorded differences between these water timers. Check the full specification table below for details and conditions.

Feature differences among your selected devices

Bluetooth (connectivity): Meross Smart Sprinkler Timer MST200 — No; Sonoff Hydro ONE Lite — Yes (Bluetooth Low Energy powers SONOFF's Proximity mode, which lets a phone control the valve and set schedules directly when there is no Zigbee gateway or the outdoor signal is unstable. Zigbee mode and Proximity mode are used one at a time, not together.).
Child Lock (features): Meross Smart Sprinkler Timer MST200 — No (The official feature list describes one-touch manual watering on the two zone buttons and never mentions a child or button lock.); Sonoff Hydro ONE Lite — Yes (With the child lock on, the local button is disabled and control is only available through the app.).
Water Consumption Monitoring (features): Meross Smart Sprinkler Timer MST200 — Yes (Real-time and historical water consumption per zone in the Meross app.); Sonoff Hydro ONE Lite — No (No flow meter. SONOFF's Hydro series comparison shows the flow meter on the Hydro ONE and the Zigbee Smart Water Valve, and marks it absent on the Lite, which is the difference between the two models.).

Sonoff Hydro ONE Lite: No
Catalog note
SONOFF's Matter bridge device list covers its Hydro water valves 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 in.

Google Home

Meross Smart Sprinkler Timer MST200: Meross Hub required
Catalog note
Listed as supported on the official product page, through the Meross Smart Hub the timer is paired to.
Sonoff Hydro ONE Lite: Yes
Catalog note

Home Assistant

Meross Smart Sprinkler Timer MST200: Meross Hub required
Catalog note
The community Meross LAN integration for Home Assistant (HACS) reaches the timer through the hub. MST200 support landed in the 6.0.0 alpha line, where testers report both zone switches and the per-channel watering settings working; the 5.x releases detect it as an MST100 and expose only one zone.
Sonoff Hydro ONE Lite: Yes
Catalog note
SONOFF documents the Hydro ONE Lite on Home Assistant through both Zigbee2MQTT and ZHA, listing which features each exposes. ZHA additionally needs the script SONOFF publishes; without it the valve arrives as a plain on/off entity.

Matter

Meross Smart Sprinkler Timer MST200: No
Catalog note
The official product page's compatibility matrix marks Matter and Thread as not supported.
Sonoff Hydro ONE Lite: SONOFF Hub required
Catalog note
The valve is not a Matter device itself: it is Zigbee 3.0 only. SONOFF republishes its Hydro water valves to Matter through its bridges (ZBBridge-U, iHost, NSPanel Pro, or eWeLink CUBE with a SONOFF Zigbee dongle), exposing valve configuration and control.

SmartThings

Meross Smart Sprinkler Timer MST200: Meross Hub required
Catalog note
Listed as supported on the official product page, through the Meross Smart Hub the timer is paired to.

Irrigation Volume

Meross Smart Sprinkler Timer MST200: No
Catalog note
The official scheduling spec is time based only (start time, duration, frequency); water use is reported, not used as a stop condition.
Sonoff Hydro ONE Lite: No
Catalog note
