What it needs to work

Manufacturer: the Zigbee version requires a Zigbee gateway, bought separately; the device is added as a sub-device of the gateway in the MOES app.

Suitable gateways and hubs

Buy with installation

Check compatibility

Connectivity: Zigbee
Maximum load current: 20 A
Energy metering: Yes

A 3 kW heater overloads an ordinary 10A smart relay; the ZS-SR-EUB holds 20A / 3500W, switches both poles and shows energy use in kWh in the app, over Zigbee via a gateway.

Connectivity and compatibility7

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, 2.4 GHz. The switch has no Wi-Fi radio [1]
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 requiredManufacturer: the Zigbee version requires a Zigbee gateway, bought separately; the device is added as a sub-device of the gateway in the MOES app [1]
Matter support — what it means Whether the device supports the Matter standard, directly or through a bridge. Matter lets you add it to Apple Home, Google Home, Alexa and Home Assistant.	NoMatter is not claimed: the device runs Zigbee 3.0; compatibility is listed with Alexa, Google Assistant, MOES, Smart Life and Tuya. Exposure to Matter via a bridge gateway is not described for this model [1]
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 a hub or coordinatorMOES does not claim Home Assistant support; as a Zigbee 3.0 device it connects via a Zigbee coordinator (ZHA, Zigbee2MQTT). Whether energy data is available depends on the model's support in the integration [1]
Works without internet — what it means Whether the device keeps working over the local network or through a hub when the internet is down. Cloud features (remote access, voice assistants) need the internet.	Not stated by the manufacturer
App — what it means The maker’s app used to set up and control the device.	MOES (recommended), Tuya Smart / Smart Life [4]
Radio frequencies and transmit power	2.400–2.483 GHz, up to +10 dBm [1]

Power and load4

Maximum load current — what it means The highest current the switch handles continuously (resistive load). A 2 kW boiler draws about 9 A, a 3 kW one about 13 A; current headroom reduces contact heating.	20 A“Max Current: 20A” in the product page specs, the manual and the datasheet [1]
Maximum load power — what it means The highest appliance power the manufacturer allows (resistive load). Compare it with the rating plate of your boiler, convector or air conditioner.	3500 W [2]
Supply voltage — what it means The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.	95–250 V AC, 50/60 Hz [1]
Power source — what it means Where the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery.	230 V mains [1]

Control and features8

Switched poles — what it means A single-pole switch breaks only the live wire; a double-pole switch breaks live and neutral together, so after switching off no conductor of that line stays live at the appliance.	Double-pole (live L and neutral N)“1 Gang Double Pole Switch”: disconnects the load's live and neutral at the same time (wiring diagram in the manual) [1]
Energy metering — what it means Whether the switch shows in the app how much the connected appliance uses: live power and accumulated kWh.	Yes“Smart Electricity Metering”: real-time monitoring and usage history in the app [1]
Measured values — what it means Which quantities are measured and shown in the maker's app. “Energy exported to the grid” means counting production, e.g. from a balcony solar kit. Via a third-party hub some of this data may be missing.	Energy (kWh)Instant power, voltage and current are not listed separately by the maker [3]
Control at the wall — what it means How the load is switched on the device itself, without a phone: touch panel, mechanical button or rocker.	Mechanical buttonOne large push key on the front; per the manual, holding it for about 7 s resets the Zigbee pairing [4]
Timers and schedules — what it means Which timers the app offers: time schedule, countdown, auto-off after a set time. For example, to have a boiler heat water only at the hours you need.	Time schedule, Countdown, loop timer, auto-off after a set timeOn the official image: Schedule, Countdown, Circulate (loop timer), Random, Inching (auto-off after a set time) [5]
Overload protection — what it means What happens when current, voltage or power exceed the set threshold: the device cuts the load or only sends a notification. It does not replace the circuit breaker in the panel.	Not stated by the manufacturer
State after power restore — what it means What state the load returns to when power comes back after an outage: on, off, as it was before, or the opposite. The options you can choose in settings are listed.	Off, On, last stateManufacturer: the relay state after power is restored is set in the app — OFF, ON or “Remember last status” [6]
Channels — what it means How many separate loads (light circuits, appliances, motors) the device controls independently.	11 key, 1 double-pole output (“1 Gang Double Pole”) [4]

Housing and installation5

Neutral wire (N) — what it means Whether the wall box needs a neutral wire. Older wiring often brings only the live wire to the switch; then pick a model that works without N.	RequiredManual: “Neutral Wire is required” — the wall box must contain a neutral wire [4]
Mounting — what it means How and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket.	In a wall boxEuropean-standard (EU) wall switch for a wall box; fixed with the two supplied screws [4]
Terminal wire size — what it means Cross-section of copper wire the terminals accept. The line's wire must match the rating of its breaker.	Not stated by the manufacturer
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.	86 × 86 mm (front plate); in-wall body 48.5 mm high, 30 mm deep [7]
Certifications — what it means Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).	CE (2014/53/EU, 2014/35/EU, 2014/30/EU), RoHS 2011/65/EUEU declaration of conformity by Wenzhou NOVA New Energy Co., Ltd [4]

Model and version1

Colour — what it means The housing colour of this model. Other colours in the same series are separate products.	GreyVariant “Grey” (SKU ZS-SR-EUB-GY-MS); the maker's photos show a dark grey (anthracite) shade [1]

Package contents2

Manufacturer warranty — what it means The warranty period the maker states. Confirm warranty terms in Moldova with the seller.	24 monthsPer the warranty card in the manual; the regional seller's terms may differ [4]
Package contents — what it means What comes in the box, per the maker.	Smart switch 20A ×1, screws ×2, user manual ×1 [1]
