Description
The OP-SBWF02 is a compact, dual‑channel Wi‑Fi timeswitch intended to replace a conventional two‑way socket box or to sit in an existing single pattress box. It gives two independently switched 230–240V outputs that you can schedule from a smartphone app or operate from the two on‑device override buttons. It’s aimed at straightforward domestic and light‑commercial uses where you want remote timed control of two separate circuits — for example hot‑water pump and circulation, separate heating zones, or lighting and a small appliance.

How it works and when you’d choose one
Functionally the OP‑SBWF02 is a small, wall‑mounted timer that replaces a simple socket box or receiver module and lets you schedule two circuits separately. The unit keeps schedules in one place but lets you allocate the 15 ON/OFF events across the two channels as required. Use it where you need reliable timed switching without adding a larger DIN‑rail controller or a bank of plug‑in smart sockets — for example to control a domestic immersion heater/boiler feed, a circulation pump and a secondary load, or two lighting circuits in a communal space.
It’s designed for retrofit and new wiring installations: the plastic enclosure is sized to sit directly over a standard single pattress box, the terminals accept conventional fixed wiring, and there are two physical override buttons so someone can switch either channel locally without using the app.
Controls, app and integrations
Setup and daily control are handled through a Wi‑Fi smartphone app. The manufacturer and authorised distributors now point users to the Smart Life app (widely used Tuya‑based platform); older C‑Home app support is documented as being deprecated. Through the app you can create 24‑hour or 7‑day schedules, trigger manual overrides, and operate the unit remotely when your phone has a data connection. The OP‑SBWF02 also advertises compatibility with Amazon Alexa and Google Home so you can include its on/off functions in voice routines.
Operationally the unit uses standard 2.4 GHz Wi‑Fi; it does not act as a separate bridge, so it must be within range of your home router (or a suitable wireless extender) to be controlled directly over the internet. For everyday use that generally works well, but factor in signal strength before you terminate the device into a deep wall box.
Installation and practical limits
The installer instructions make clear this is a mains wiring device and should be fitted in accordance with current IET wiring regulations — installation by a qualified electrician is recommended. Wiring is conventional: live and neutral for the module supply, and two switched outputs that are normally open. The unit is intended for indoor socket‑box mounting; it does not carry an IP weatherproof rating and therefore should not be used outdoors without appropriate containment.
Pay particular attention to the switching ratings. The OP‑SBWF02 is rated for resistive loads of 5A per channel (10A combined). Inductive loads — motors, pumps or compressors — place a different demand on the contacts; the published inductive rating is lower, and the manufacturer advises that some types of lamps (discharge or many LED fittings) are not suitable to be switched directly by this module without a contactor. If you’re switching a boiler, pump or other inductive equipment, check the device’s inductive load rating and consult the manual or installer to decide whether a contactor or a higher‑rated timeswitch is required.
Advantages and realistic limitations
- Advantages: Neat single‑box install, independent schedules for two circuits, local manual override, remote control via Smart Life and voice assistants, internet time synchronisation and small physical footprint.
- Limitations: Low per‑channel current rating compared with larger DIN‑rail timers (5A), no stated outdoor/ingress protection so for indoor use only, reliance on 2.4GHz Wi‑Fi and the Smart Life ecosystem for remote control.
In short, the OP‑SBWF02 suits anyone who needs tidy, wall‑mounted timed control of two light‑to‑moderate domestic loads and who wants app and voice convenience. It’s not the right choice where high currents, heavy inductive starting loads or direct switching of certain lamp types are required — in those cases choose a higher‑rated timeswitch or use the OP‑SBWF02 to drive a suitably rated contactor.
Finally, if you already have other Optimum/TFC Wi‑Fi products the OP‑SBWF02 fits into that ecosystem and can be managed with the same app and router constraints, which simplifies setup and grouping of devices in a home‑automation scheme.
