    Hi,

    I need a simple switch to control lighting - one lamp (on / off).
    Control from a simple remote control + possibly control via wifi (app).
    Controller to be placed in the box.

    Thank you in advance.

    There are many such solutions - type WiFi+RF in google and there are many remote controls to choose from - this is probably the simplest solution and at the same time the most stable and reliable. There are also remotes on WiFi - e.g. QN-WR01 then you don't need RF in the switch - WiFi is enough, but the switch must be within the same application as the remote.
    The zigbee+RF versions already require a zigbee gateway - but the choice of devices is greater.
    Check you have an N wire in the box before choosing - this may determine the possibilities.

    Many thanks for your reply. Can you suggest me a specific proven type or two of such controller? You may already have experience with them. They are not expensive, but I don't want to order several and test them. I want such a controller to be stable and have a status memory in case of power failure.

    See for yourself what is available considering whether it is N.
    .
    The electrical installation is being done from scratch so there will be 3 wires in the box.

    See e.g. Tuya's QL series, but I don't know if it has memory, generally if you type WiFi+RF into google you might find something that suits this particular application.
    I avoid WiFi and cloud control and I don't know too many such devices.

    Hi,
    I would like to be able to switch lights on/off via a traditional switch as well. That is, for example, I will turn off the "light" via the RF remote control and turn it on with a "flick".

    I found two types of QL Tuya controllers:
    - 1 channel - Works with a traditional switch,
    - 2 channel - Works with a traditional 2 pole switch.

    Which controller should I choose?

    .
    And what's the deal with these channels? How many remotes will a given controller be operated with?

    That is, if I want to control one lamp (one bulb) then I buy a 1-channel controller.
    However, if I want to control two bulbs then I buy a 2-channel controller.
    Is this correct?

    Can you recommend me any remotes for this series? I can't seem to find anything interesting.

    BleBox switchBox + remote control µRemote . There is also a version of this switch that controls two devices (with a 'D' at the end).

    Blebox is good, especially as you can get two-way communication and confirmation of execution. But it is not cheap. Of the cheap ones, e.g. Tuya's QL. Glass switches from e.g. Sonoff also have RF and there are similar remotes for them - but this is no longer a doped solution.

    That is, I buy a kit like the one below and can control a single lamp via the RF remote.

    Relay 1 channel QL WIFI+RF module 2300W TUYA:

    Remote control 2 function for QL ON/OFF modules:

    What do you suggest for the LED dimmer? Also control via RF.

Topic summary

✨ The discussion revolves around selecting a simple switch for controlling a lamp with both remote and WiFi app integration. Users inquire about reliable controllers that can operate via RF remote and WiFi, with a preference for devices that retain memory during power failures. Recommendations include the Tuya QL series, which offers 1-channel and 2-channel controllers compatible with traditional switches. The BleBox switchBox is also suggested for its two-way communication feature, although it is noted to be more expensive. Users seek clarity on the number of channels needed based on the number of lamps to control and request suggestions for compatible remotes and LED dimmers with RF control.

FAQ

TL;DR: For one lamp use a 1‑channel module; for two, a 2‑channel—"How many devices it will control - e.g. 2 lamps or 1 lamp." Choose WiFi+RF for simple, stable remote-and-app control. [Elektroda, sk1977, post #19866717]

Why it matters: This FAQ helps DIYers and installers pick a reliable in‑box light controller that works with remotes, apps, and existing wall switches.

Quick Facts

What’s the simplest way to control one lamp by remote and app?

Install a WiFi+RF in‑wall relay in the switch box. Pair it with an RF handheld remote and your phone app. This approach is simple, stable, and reliable. Options discussed include Tuya QL modules, Sonoff RF glass switches, and BleBox switchBox with µRemote. Ensure the relay fits your box and load. [Elektroda, sk1977, post #19825074]

Do I need a Neutral (N) wire in the box?

Usually yes. Most in‑wall relays power themselves from Line and Neutral. Without N, you must pick specialized no‑neutral models. As one expert put it, “Check you have an N wire in the box before choosing.” Verify wiring before purchase. [Elektroda, sk1977, post #19825074]

How do I choose between 1‑channel and 2‑channel controllers?

Match channels to circuits. Use one channel for one lamp, or two channels for two independent lamps. Or split a two‑circuit fixture. As noted, “How many devices it will control - e.g. 2 lamps or 1 lamp.” Leave expansion room if you might add a second circuit. [Elektroda, sk1977, post #19866717]

Can I still use a traditional wall switch alongside the remote and app?

Yes. Choose a module that accepts a traditional switch input. Tuya QL has 1‑channel versions for a standard switch and 2‑channel for a two‑pole switch. Wire the switch input according to the manual. This lets you toggle locally even after remote actions. [Elektroda, automatapl, post #19862554]

Which remotes work with Tuya QL or similar WiFi+RF modules?

Pair RF remotes sold for that module family, or use a WiFi remote. For WiFi, QN‑WR01 can trigger switches in the same app ecosystem. In that case, the switch does not need RF. Keep everything on the same Tuya‑compatible app for consistency. [Elektroda, sk1977, post #19825074]

Is a WiFi‑only remote (like QN‑WR01) a good idea?

It removes RF hardware from the switch and centralizes control in one app. However, some users prefer to avoid cloud‑dependent control. If you want resilience without internet, pick a module that also supports local RF. “I avoid WiFi and cloud control.” [Elektroda, sk1977, post #19828458]

What if I prefer Zigbee instead of WiFi?

You can use Zigbee+RF variants, but you will need a Zigbee gateway. The gateway adds cost and complexity but expands device choices. Keep all devices within the same Zigbee ecosystem for smooth operation. Confirm RF pairing options before buying. [Elektroda, sk1977, post #19825074]

I want reliable control and status feedback. Any proven option?

Consider BleBox switchBox with µRemote. It offers two‑way communication and execution confirmation. That helps verify actual relay state after commands. There is also a dual‑channel version for two loads. “Blebox is good… two‑way communication and confirmation of execution.” [Elektroda, sk1977, post #19870871]

How do I wire a WiFi+RF relay with a wall switch?

Typical steps:
  1. Power off at the breaker and verify no voltage.
  2. Connect Line (L) in/out and Neutral (N) to the relay; connect the module’s switch input to the wall switch.
  3. Restore power, pair the remote, then add the device in the app. Confirm you have Neutral available before starting. [Elektroda, sk1977, post #19825074]

Will the controller remember its on/off state after a power outage?

Check the spec for “power‑on state” or “state memory.” Some devices let you set On, Off, or Last State. The thread flagged uncertainty for specific Tuya QL units, so confirm with the seller or manual. Ask before buying to avoid surprises. [Elektroda, sk1977, post #19828458]

How many remotes can control one module?

It depends on the module’s firmware. Many allow registering multiple RF remotes. Check the datasheet or product page for the pairing limit. If you plan several remotes, verify capacity before purchasing. Choose a family with readily available remotes. [Elektroda, sk1977, post #19825074]

Can I dim LEDs via RF as well?

Yes. Use an RF‑capable dimmer matched to your LED type. For 12–24 V LED strips, pick a PWM LED controller. For dimmable 230 V bulbs, choose a mains dimmer rated for your load. The thread references a 12–24 V RF LED controller option. [Elektroda, automatapl, post #19880687]

What about Sonoff glass switches with RF?

They provide RF control and have matching remotes. They replace the wall switch rather than sitting behind it. Evaluate their aesthetics and app ecosystem for your room. Ensure they meet your wiring and load needs before choosing. [Elektroda, sk1977, post #19870871]

My installation has three wires in the box. Does that help?

Yes. With Line, Neutral, and a load conductor present, most in‑box relays will work. This expands your options to standard WiFi+RF units. It simplifies wiring and avoids no‑neutral workarounds. Confirm conductor identification before connecting. [Elektroda, automatapl, post #19827673]

Can one unit control two separate lamps independently?

Use a two‑channel controller. It lets you switch each lamp independently from one module. BleBox offers a two‑channel “D” version. Tuya also sells two‑channel variants for dual circuits and two‑pole switches. Verify total load and box space. [Elektroda, exti, post #19870827]
