Netatmo Modulating Thermostat and hot water control

I've installed the Modulating Thermostat, it can control heating, but not the hot water.

Their documentation lacks any details and the one thing they have on their site - https://helpcenter.netatmo.com/en-us/smart-modulating-thermostat/search/how-does-the-domestic-hot-water-control-work?query=hot%20water - actually does not work, since there is no "advanced settings" in the whole app to be found.

Any ideas?

​

I'll give it a few days and then probably return it, since their support isn't very supportive, their manuals are more manual "try something if you're tech savvy" oriented than proper guides, and their documentation actually lacks any documents and is faulty and misleading...

Also the problems after power failures (like you unplug it from the wall, plug it back in and it does not work with any app [homekit or their fabulous home + control]) aren't helping the image of the brand either.

​

And yes, I have an OpenTherm boiler - Viessmann Vitodense 111-W B1LD with a water tank.
