It does what it says. I wanted to control some lights remotely and it's just what I needed. Small and economical. I also bought the switch but you can use any garage door remote. Pairing is very easy

The setup with my phone was done very quickly, without any hassle. It works perfectly with Alexa, and I like that I can turn on the lights from my phone or simply with a voice command. It really made things much easier for me with my devices!

I have worked with over 40 Sonoff products. This one is very stable! It inspires confidence, it doesn't do silly things like disconnections, etc. For what it does, it is really very good VFM.

The intermediate switches are amazing!!!! The ewelink application is one of the most stable I have found... The switches are connected to Google Smart Home and the commands work without any problem!!! I also have the smart water heater working!!!! For two years, not a single device has broken

It was installed and connected easily. I control it with the Sonoff RM433-R2. I placed it in the kitchen hood.

Oh, that Chinese guy. Flawless gadget. I installed 6 Sonoff RF2 and 6 double Sonoff RF switches in an old apartment that previously had one socket and one switch in each room, and suddenly with 70 euros, the apartment became smart, with double switches in every room (connected via RF with Sonoff adhesive switches) + the ability to give commands via WiFi. Plus, the lights now have two levels (without needing to pull a second phase). I gained an extra socket since the regular switches were abolished. The intermediate switches were installed inside the light fixtures (in one fixture, I had to remove the switch covers to fit them). It took 30 seconds to set up the RF commands, only the WiFi connection gave me a hard time because it requires a little patience.

It works perfectly as always. BUT unfortunately, even though I paid to have it the next day, it arrived after 2 days. I sent the relevant messages but received no response.

It works perfectly, it takes a bit of noise to adjust the RF, describes a friend the process in another review.

Perfect! It opens and closes any device from anywhere with Wi-Fi and up close with an RF remote control. Its use depends on everyone's imagination.
Through the eWeLink application, you can do many things. Highly recommended!

It's funny that something so simple cannot have simpler and clearer installation instructions! We spent an afternoon trying to figure out what was going on with the connection, but in the end, we managed to do it! From there on, it works perfectly through its application, but also through the wireless Sonoff controller (which also had different instructions and we couldn't make sense of it) and even though it says that in case of interruption it needs to be reconnected, we didn't need anything. Its application is okay and the good thing is that you can use it from a distance (outside the house).

The fact that it forces you to use an app, give email, phone number, and with GPS tracking, all just to open and close a relay, I consider it excessive intrusion. I didn't even bother installing it.

Perfect! Easy electric connection. Also easy WiFi setup. Very good app on mobile. Many customization options.

I have it for a few days and it works perfectly!
It connects easily to wifi through ewelink.
The way to set up the RF is different from what the manual describes.
1) Hold down the switch on the sonoff until the blue LED flashes red momentarily.
2) Press your RF switch.
3) Press the sonoff once again.
4) Press the RF switch once again... and it's ready!

I have connected one sonoff and two RF switches... creating a wireless "alle retour" setup... very convenient!!!

It works great with Alexa and Google Assistant, it recognizes it as an outlet.

I give it 4 stars instead of 5 because it took me 2 hours to figure out how to connect the RF... due to the incorrect instructions in the manual.

It is cheap, works well and fast. For the initial wifi connection, the eWeLink application is required. Also, through this application, options such as on/off, timer, scheduled functions, etc. can be set. The eWeLink application is generally average. Furthermore, with Google Home, you can open/close the switch and see if it is on or off. However, you cannot schedule tasks (e.g. to close in one hour, etc.) through Google Home. The device can be controlled whether you are within the network or remotely. I mention the Google Home application because compatibility is important for anyone who has multiple devices of this kind from different brands. If they are not compatible with Google Home to gather all the information there, then you end up with many similar applications, which is completely impractical.

I have installed it in series with a power relay to control the water heater (do not install it without a relay for loads over 1kw).
In the approximately one month that I have had it, it works perfectly. Easy installation through the ewelink application. Control via the internet or remote control in case the router signal is not good where you will place it (e.g. a rooftop like in my case). Of course, time is a very important factor in evaluating such a device...

Excellent product, you can open and close the lights in your house via the internet and it also has an excellent programming system.
Also, the rf control is amazing, you can program separate buttons for separate devices. I couldn't connect to the network with an old router.
