How does the T3 differ from the T2 and T0 in the TX range?

The T3 pairs black tempered glass and a frame with a 433.92 MHz RF receiver. The T2 is the same electronics in Ultra White, and the T0 is the base model without RF. All EU 1-gang versions carry a 2 A relay.

Is the RF remote included in the box?

No. The T3EU1C only carries the 433.92 MHz receiver; the remote (such as the SONOFF RM433R2) is a separate purchase. Pairing is quick: hold the touch button for 3 seconds, then press the chosen key on the remote.

Do I need a neutral wire in the wall box?

Yes, the wiring diagram calls for both live and neutral. If the switch point only has a broken live — common in older buildings — pull a neutral during renovation or pick a no-neutral module such as the Sonoff ZBMINIL2.

How much load can it switch?

The relay is rated 2 A at 100–240 V; for LED lighting Sonoff quotes up to 300 W per channel at 220 V. It is meant for lighting circuits — chandeliers, sconces, track lights — not sockets, boilers or pumps.

Can you find the black panel at night on a dark wall?

Yes. The touch zone has an LED locator: a soft glow marks the button in the dark, so the switch is as easy to find as a classic white one. In daylight the marker all but disappears against the black glass.

Does it fit a standard European wall box?

Yes, the T3EU1C mounts in a regular round EU back box; the panel measures 86×86 mm with an overall depth of 35 mm. Sonoff recommends an installation height of up to 2 m.

Are there 2-gang and 3-gang versions in the same black glass?

Yes, the T3 comes in 1-, 2- and 3-gang versions of the same design, so the whole flat can stay visually consistent. The black 2-gang variant is coded T3EU2C-TX and is also available at CasaSmart.

Will it join a 5 GHz-only Wi-Fi network?

No, the TX series works on 2.4 GHz only (IEEE 802.11 b/g/n, 2412–2472 MHz). If your router broadcasts one SSID for both bands, split the networks while pairing or temporarily disable the 5 GHz band.

About this product

A matte-black feature wall deserves better than a white plastic switch — and that is precisely the gap the T3EU1C fills. Its 86×86 mm panel of black tempered glass carries a slim frame and an LED locator that keeps the touch zone visible at night.<br><br>A light tap switches the line instantly, with no mechanical click. The eWeLink app adds schedules, scenes and shared access; Alexa and Google Home handle voice; LAN mode keeps app commands local if the internet drops. A built-in 433.92 MHz receiver takes an optional RF remote. Installation needs live and neutral; the 2 A relay is meant for lighting circuits.

Where it works

Use cases

Home

On a graphite living-room wall the black T3 panel replaces the stock white switch and drives the track lights; an Evening scene dims them with one tap.

Home

Against dark wallpaper in a Chișinău flat the soft glow of the touch zone marks the switch at night, so the light goes on without hunting along the wall.

Home

An RM433R2 remote on the coffee table kills the lights with no phone and no Wi-Fi — the 433.92 MHz receiver inside the switch takes the command directly.
