Connectivity: Wi-Fi, RF 433 MHz
LED load per channel: 150 W
Neutral wire (N): Required

Dimming the bedroom from the nightstand takes one press on the RM433R2 remote, while Wi-Fi gives the budget-friendly D1 schedules, voice control and sunset scenes in eWeLink.

No separate hub required

Connects to the router over Wi-Fi and is added to eWeLink directly; the remote talks to the module directly.

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.	Wi-Fi, RF 433 MHz2.4 GHz Wi-Fi (IEEE 802.11 b/g/n) and a 433.92 MHz radio link for the RM433 / RM433R2 remote (receive only on the D1) [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.	No hub neededConnects to the router over Wi-Fi and is added to eWeLink directly; the remote talks to the module directly [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.	NoOfficial documents list only 2.4 GHz Wi-Fi and 433 MHz RF; Matter is not mentioned [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 the maker's integrationOpen REST API over the LAN (DIY mode): the ITEAD page names Home Assistant explicitly. No separate official SONOFF HA integration is stated [2]
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.	YeseWeLink 'LAN control' and the device's HTTP API on the local network [1]
App — what it means The maker’s app used to set up and control the device.	eWeLink [1]
Radio frequencies and transmit power	Wi-Fi 2412–2472 MHz; RF 433.92 MHz (receive only on the D1) [3]

Power and load5

LED load per channel — what it means Total LED lamp wattage per channel that the maker allows. Add up the watts of all lamps on that circuit and compare; for dimmers only dimmable lamps count. If the maker gives the figure in VA or as a total for all channels, the note says so.	150 WDimmable LED lamps only [1]
Max power per channel (resistive) — what it means Power of incandescent lamps, 230 V halogen lamps, heaters and other resistive loads per channel. For LEDs, motors and power supplies the permitted power is lower — see the separate figures.	200 WIncandescent lamps. Manual: the module may only be used with incandescent and dimmable LED lamps [1]
Max current per channel — what it means The highest current one channel handles with a resistive load. For LED lamps check the separate “LED load” figure, which is usually noticeably lower.	1 A'Max. current 1A' on the official ITEAD page; the manual does not state a current [2]
Minimum load — what it means The lowest lamp wattage on the circuit at which the device works reliably. It matters for no-neutral wiring and for dimmers with LED lamps: below it, lights may flicker or glow faintly when off.	Not stated by the manufacturer
Supply voltage — what it means The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.	100–240 V AC, 50/60 Hz [1]

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.	RequiredTerminals: N In, L In, L Out; the manual requires correct neutral and live connection [1]
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 boxITEAD page: fits 86-type, EU and US wall boxes [2]
Dimensions (W × H × D) — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	62 × 47 × 32.5 mmAs printed in the manual; per the ITEAD drawing: 62 mm high, 47 mm wide, 32.5 mm deep [1]
Housing material	Polycarbonate (PC), V-0 flame rating [1]
Certifications — what it means Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).	FCC, CE [2]

Control and features4

Wired wall switch input — what it means Whether you can keep an ordinary wall switch or push button and wire it to the module, so the light works from both the switch and the app. Shows which switch types are supported; on dimmers a momentary button usually also adjusts brightness when held.	No inputNo switch input: only N In, L In and L Out terminals. Control is via app, voice and the 433 MHz remote; a separate wall base for the RM433 exists (not included) [1]
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.	On, Off, last statestartup parameter: on / off / stay (as before the outage); in the app — 'Power-on State' [4]
Overheat protection — what it means The module cuts or reduces the load by itself if it gets too hot inside the box. A dimmer in a cramped wall box heats up more than an ordinary relay.	Not stated by the manufacturer
Channels — what it means How many separate loads (light circuits, appliances, motors) the device controls independently.	1 [1]

Package contents2

Remote included — what it means Whether a remote for phone-free control is in the box. The remote’s link type is shown under “Connection protocol”; compatible remotes sold separately are listed by the manufacturer.	YesCurrent 'D1 + RM433R2' kit (kit quick guide V1.1, 2024) and the ITEAD page: remote included, its wall base is not. The older manual V1.1 (2021) said the RM433 was sold separately [3]
Remote model	SONOFF RM433R2 (433.92 MHz)8 buttons: on, off, 4 brightness levels (hold for smooth adjustment), clear pairing, Wi-Fi pairing mode [3]

Lighting2

Dimming method — what it means How the dimmer cuts the mains sine wave. Trailing-edge dimming usually runs dimmable LED lamps more quietly and with less flicker; leading-edge is designed for incandescent lamps and conventional transformers. Universal models pick the mode themselves or let you switch it in settings.	Not stated by the manufacturer
Min/max brightness calibration — what it means Whether you can set the lowest and highest brightness to suit your lamps. This helps remove flicker or buzzing of LED lamps at low brightness and avoids the dead part of the scale where the lamp no longer lights.	YesApp setting 'Set brightness range'; the LAN API exposes brightmin and brightmax [1]

Operating conditions1

Operating temperature — what it means The air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms.	−10…40 °C [1]
