and this does what it should. I connected it to the water heater (via relay) and it works just fine!
Does exactly what its for and in my case i wanted a remote on/off switch for the water heater. Best works with a 2 pole relay for safety. Only bad thing is that its manual in the box doesnt exactly guide you through the app set up but its 2024 and everything is on the Internet and Youtube!
Such a small thing makes a big difference!!!! I use it on the water heater and I have it set up with the motion sensor of the same brand so that when the front door opens, the hot water turns on. The installation on the panel requires a relay, the whole process cost me 30 euros. Setting it up with the ewelink app took a bit of effort, but it was worth it. Attention! Make sure to connect it to the 2.4 frequency of your wifi!
The only negative is that it requires a bit more effort in coordination compared to other products in the same category from the company.
It's great, it does what it says, just remember that you can't turn off the switch because you're cutting off its power.
Easy to use and connect to the app. It works ONLY on the 2.4Ghz band, so be careful when searching. Pairing is done within 1 minute and it's complete. It is used for a solar water heater and has made things easier for us when we program it to turn on when needed during the night.
Overall very satisfied with very good range easily 25 meters and what is single at 16 amps I work normally on a water heater also the quadruples that also have rf work perfectly and price very good also very easy installation inside the panel with the fuses is a bit bulky the quadruple but otherwise very satisfied also very easy setup with wi-fi and with the rf remote control
Good device, works as it should. Easy installation on the panel rail with its extra base. Good handling from the application. Simple and functional with timer function, programming, etc.
Pay attention to the wiring and installation. For remote control use of the water heater, I recommend using a power relay for greater safety in the electrical installation. Although the device has a nominal current of 25A and covers the use of water heater control, I did not trust it and used a relay. It is still a simple Chinese construction that needs to supply enough kW to the water heater, which is one of the largest household consumptions. Because I have seen various videos, etc. using the device on a water heater by essentially cutting off the power circuit, I am providing a rough wiring diagram of the device using a power relay, which I consider safer. Be careful if you are not familiar, ask for help.
It looks good for its price.
I bought an extra 25A power relay and installed it!
I have programmed it for a week now and everything is fine!
Now we will see how it goes in the future...
It works as expected. I have no complaint.
However, be careful, you need to connect the phase and neutral inputs to the corresponding L and N. If you connect them incorrectly, as mentioned by someone else in the comments, both output contacts will have voltage when turned off.
Connects instantly, the application covers other similar products as well, it does what it is intended for.
Used for wireless management of the water heater (smart), it works perfectly, easy to set up and manage.
I must have around 30 Sonoff switches, many of which are Basic version 1 and 2.
They do what they are made to do, to tell the truth I never found any differences between the two versions in practice
I have been using products from the same company for many years. They are reliable, functional, and easy to install.
I installed this switch to control my water heater. The installation was done in parallel with a manual circuit breaker so that I can operate it as I want. In the installation, a 4A fuse was installed to protect the switch, a power relay that receives commands from the Sonoff, and a 20A automatic circuit breaker to protect before the relay. It works perfectly and flawlessly so far, and there has been no WiFi interruption. It can be controlled with the ewelink program through scheduled operation, timer, and of course, immediate on or off.
Edit: After 5 months of continuous use, it continues to respond correctly without any WiFi interruption!
I will agree with all the good reviews that other users have written.
Value for money!
It connects immediately, works without problems, and works perfectly with Google Home.
However, I will not give it 5 stars, but only 3, because of an electric shock I experienced because of it.
The problem?
While the switch is in the Off position, and both output contacts (both L and N) are at 220 volts - when the switch is activated, it only provides 0 volts to N in order to create the voltage difference of 220 volts.
Which twisted mind thought of this operating method?
And while this should be mentioned in bold in its accompanying documentation for safety reasons, it is not mentioned at all!
Very good little thing, easy to connect, I installed it on the water heater, it works perfectly, it has the ability to shut off on its own after the time you set. I have set it to shut off in 25 minutes twice a day, before I go to work, so that I have hot water, and after work, so that I can take a shower without worrying if there is hot water. Guys, it's worth the money, at 6€, come on, it's the best
Awesome. Instead of dealing with the panel, I directly installed it on the water heater and the story was over
Everything is exactly as I expected. It connected easily to the (2.4Ghz) wifi. After downloading their app, I named it, set it up, and connected it to Google Home within a few minutes.
BUT, the most important feature for me has a big problem. I am referring to the automatic switch-off after a few minutes. I got extremely confused because there are 2 ways to activate the automatic switch-off through the app.
And with both ways, even though I had set the device to switch off after 20 minutes of operation, I had different incorrect results. One time it turned off after 5 minutes, another time after 10, another time after 7, and occasionally, after the actual 20 minutes that I wanted.
I contacted the creators of the app, and they told me to restart the device. Obviously, this did not fix the problem and unfortunately, I have to keep in mind to ensure that the device operates within the desired time frame.
Apart from this issue, I am very satisfied with how the device functions
The best thing that has come out. I have been using it for 6 years without any disconnections and with daily use. I already have 10 of them
I installed a SONOFF BASIC R2 inside the household electrical distribution panel along with a double remote power relay (Hager ESC225 25A) to implement a timer for the water heater, in order to take advantage of the nighttime electricity rates. Currently, the system works perfectly. The water heater automatically turns on every morning at 6:20 and turns off at 6:50.
1st SOLUTION FOR INSTALLING THE SONOFF IN A PANEL
Because the SONOFF BASIC R2 cannot be directly mounted on the panel rail, there is a suitable accessory (Sonoff DR DIN Rail Tray, with code SNF-DR) that serves as a base for easy installation of the Sonoff switches on the distribution panel rail. This allows you to mount the SONOFF inside the panel. However, it will not protrude much like the miniature circuit breakers of the panel, making it easy to access the SONOFF button to manually activate the water heater. If you want easy direct access to the button, you will need to find a way to mount it (for example, I screwed the SONOFF on the front of the panel but from the inside, so it is at the same level as the other circuit breakers, see attached photo). On my mobile phone, I installed the recommended eWelink application to manage the Sonoff.
2nd SOLUTION FOR INSTALLING THE SONOFF IN A PANEL USING THE SPECIAL BASE
The Sonoff switch was placed on a rail using the special base "Sonoff DR - DIN Rail Tray" available in the market. Other Sonoff products (such as Sonoff Basic, Sonoff RF, Sonoff Pow, Sonoff TH10/16, Sonoff Dual, Sonoff G1) can also be screwed onto this base, allowing them to be installed on a DIN rail in the household electrical distribution panel. The system works perfectly with the eWelink application on the mobile phone.
However, what the base does not do is bring the Sonoff "face" (see same level) with the other switches on the panel. So the Sonoff remains "embedded" inside the panel, which is not very safe when you want to manually activate it by putting your hand inside.
If someone wants to bring the Sonoff "face" (see same level) with the other switches, I describe a simple and functional solution that you can find on Skroutz in my review for the "Sonoff DR DIN Rail Tray" (look for the review for the product "Sonoff DR - DIN Rail Tray"). See attached photo.
The classic Sonoff works just fine....
This is a somewhat new version and during the pairing process in the app, it wouldn't connect to the 5GHz router of Cosmote no matter what, while when I turned off the 5GHz and left only the 2GHz, it eventually connected at some point....
It connected immediately to another 2.5GHz router
It works perfectly, for some reason it pairs with the mobile app the second time, it doesn't find it the first time, the same thing happened with two different routers, a minor inconvenience since it only happens the first time you connect it, even if there is a power outage when it comes back on, it is ready to use.
It is exactly what it describes. Reliable and easily connects to the home wifi. The application has many options for settings.
I have bought 2, one I have used as a power strip and the other I have installed for the water heater, I haven't encountered any issues, they work perfectly
There is no better patent than this one, really!
We have been using them for years, never had any issues.
And it works perfectly with the iPhone application.
Very simple but requires the cable to be cut or inserted somehow in order to work as a switch. It definitely needs a neutral wire, so it is not suitable for places like old lights that only have interruption in the phase.
It worked perfectly with the standalone switch Sonoff RF-T2EU1C in the adjacent room. It also works with Google Home as long as you add it to the Sonoff application (eWeLink) and import it into the Google Home application.
A great product... I use it in my 3D printer for remote shutdown when the printing is finished. I am completely satisfied.
To connect with the eWeLink app on iPhone, the compatible pairing mode was required, for which you can find instructions on the official site/manual and in a video on YouTube. It is used to control a power relay for a water heater. It works flawlessly. You can program when it will turn on, when it will turn off, what it will do when the power comes back after an outage (on/off or as it was before the power went out), as well as how long it will stay on before turning off (inching), regardless of how it was turned on. All through the app.
Very easy and practical. It pairs the first time it gets power. Then I set up a recurring automation and that was it, I find the bathroom warm every day when I come back from work. Perfect.
