I bought this smart thermostatic valve so I wouldn't have to get out of bed in the middle of the night. I regret it now. It wasn't clear which adapter to use for my radiator, and then fitting the valve itself onto the RA adapter was almost impossible. Then there's the controls. Whose idea was it to have the valve open based on temperature?!?! You set the temperature to 25°C, but guess what? The thermometer is in the valve head, where the surrounding area heats up instantly from the radiator, so the valve closes after a few minutes and doesn't heat the room at all. The app is a disaster. It constantly defaults to the schedule; wherever you click, it brings up the 'schedule', which is useless if you work different shifts every time. If you want to open the valve in the app, you have to adjust the temperature by sliding it in a tiny window, but even then, it only opens the valve for a few minutes before closing again. I've been trying to heat the room for 6 hours now, with no success. I will be returning it.
There are no pros.
Complicated to attach the valve
Cheap plastics
The built-in thermometer is useless
The app is dreadful
Requires GPS and Bluetooth at the same time

I have been using Danfoss for about 10 years (older models) without problems
simple, no need for additional equipment
holds the set temperature quite well

The product works rather strangely, it does not follow the values set in the application. I'm thinking of returning it.
The control application is very vague and not described in detail.

More expensive than programmable valves, but worth it. Settings in the app ok (high/low temperature) and schedule. It communicates quickly, I have not noticed any longer or slower delays. Hassle-free installation and battery replacement. The control is open/close by default, but in the settings you can also select the option of some kind of predictive mode. Everyone addresses ~ and I did too, that the wheels and reducers are plastic. But my old manual danfosss valve was also plastic. How it works I don't know, we have the temperature set to 21 but in our apartment building it is always about 23-24 degrees. We'll see when it's freezing.

The product was purchased with the idea of installing it in the bedroom so that the heating would be dimmed at night and not heat unnecessarily during the weekdays. With the understanding that it will turn on some time before the alarm, it will not heat during the weekday, and then start again when I return from work. I've had the device for a year and it has never worked like this. In the morning it did not turn on, the heater remained cold despite the large temperature difference between the desired temperature and the temperature on the head sensor (in the application itself). The manual temperature setting does not work either.
Incompatible by default with RTD-N type valve from the same manufacturer
The RTD-N attachment is difficult to find
It does not keep the set temperature, the difference is 5 degrees (between the set temperature and the required temperature) and the head does not heat.
Setting temperatures by day and hour does not work.
The control app often doesn't connect, the app for some unknown reason requires gps on to use.
The instructions are generic and misleading, most of the described features are not observed on the device.
Manual temperature setting also does not work

Very good product, used over aq year before passing to the zigbee version in order to have additional temperature sensors. Quality is excellent, battery life is excellent too. I was very happy with it and it is still used in my parents appartment
works very well
easy to install
reliable and precise
temperature mesured on the unit itself, can be tricky if it is covered by curtain
