5 stars simply! I have connected all my blinds at home without any issue, it just needs a neutral to work. I used an external switch as it didn't fit in the built-in switch.

I don't like to give bad reviews for a product. Some people have put a lot of effort into creating it. The only reason I will do it in this case is that some others have tried to create a much better product and that should be rewarded. Let me explain:
Is the sonoff dual r3 a bad product? Answer: Absolutely not. It is a decent product and does its job well. If you use it on its own, using the official app, you won't have a big problem. I use it to open and close shutters through HomeAssistant. This brings me to the first issue, the integration with HomeAssistant. To make the integration work, you need to input the username and password of the eWelink app into an external module of HomeAssistant and it needs to be always online. Call me strange, but I don't feel comfortable with that for many reasons. Is there any other problem? Yes, it is huge and doesn't fit in any European box. How big is it? Look at the photo I attached comparing it to the Shelly 2.5, which is by far the best product in this category. What can we do, the guys at Shelly did a great job and that's the truth.
In my opinion, no regular user should choose it over the Shelly 2.5. The one-time difference of 10-15€ is very small for what you will ultimately get in your hands. For the rest of the users (those who want to play with gadgets), I have the following to say: 1. It easily supports esphome, which completely changes it at the software level and frees it from the sonoff's eWelink. After that, it improves significantly at the software level, but still falls short of the Shelly. 2. The process is not something special, but it's not for a user who doesn't have the willingness to get involved a bit. I have uploaded the yaml config file for esphome here for anyone interested: https://github.com/gmeles/dualr3_esphome/blob/main/sonoff_dual.yaml 3. Its advantages over the Shelly are that it has the new esp32 module, which has Bluetooth and more GPIO. I'm not sure who will make use of these, but it's not bad to have them.
In conclusion, it is a good device, but it has a rival in an excellent product with a standard implementation. The decisions are yours

    It works just fine with electric shutters (blinds) where it was installed, both with the Sonoff (eWeLink) app and with Google Home. It's just a bit large and it barely fits, with much difficulty, in the classic blue round switch boxes; it would be good for the electrician to plan to install slightly larger boxes if this particular switch is to be installed

    I have installed it on external awnings and connected it to a Google Nest, so I can raise and lower them with my voice. It needs to be connected to its app on your phone first, but after that you use it permanently from the Nest. I was afraid of the Shelly because some people say they break after a power outage, I don't know if that's true, but I've had this one for months, the power has gone out many times and I haven't had any issues.

    It is just what you need for automation of the blinds. I highly recommend it!!! However, be careful as it requires a neutral and does not fit behind the outlet box. I opened the junction boxes near the blinds and placed them there.

    I installed 4 devices. 2 broke down in one day. Specifically, they stopped responding to the physical switch. From WiFi, you could control them normally.

    I replaced both of them and there is no longer a problem.

    Flawless. Installed 1.5 years now, it works continuously. It raises and lowers the blind by itself according to what I have set. Every day at a specific time to go up and a specific time to go down. Very convenient and very economical. It has stuck a couple of times, where I simply reset it to connect through the application. All good though. Convenient if you have plants and want them to have light even when you are away, so the blind goes up and down as you wish, as well as if you are away from home to not look closed and empty.

    This product is easy to connect and operate with several automations. It is designed to handle two lines and at a very affordable price. WARNING: It does not have dry contact, meaning the lines it opens and closes have current!

    Very good functionality. I applied it to a home installation box for controlling the electric roller. Many operating options (direct opening-closing of the roller) either individually as long as you press the switch or through the application. It has been working without any problems for a year now. I just had to cut the plastic base in the middle of the box for the cover and replace the existing cover with another one with handles.
