All my radiators turn on at once even when I just turn on one room
I have four radiators and two heated bathroom rails in my flat. I bought four Taco Smart Radiator valves and put them on the four radiators. I've set them all up successfully as separate rooms, with no error message. But when I turn on one 'room', all the radiators heat up rather than just the one 'room' I have selected to heat. I have tried changing the zone controller to both assigned and not assigned but the same thing happens.
I also wondered - if everything was working correctly, and all my 4 rooms could each heat up separately, would this be technically possible: If I turned the heating 'on' on the app, and then turned off each of the four 'rooms' separately would that leave it so that my bathroom rails (which are connected to the same system and boiler) would heat up but none of the four radiators?

In answer to the first para: sounds like the trv heads either aren’t screwed on tightly enough or you need an adapter.
Second para: no, if no rooms were calling for heat then the heating would be off.1 -
@johnnyp78 Thank you for your reply. Do you know if there is a way to tell when they are screwed tightly enough? There are no error signs.

The plastic base needs to be as tight as it can go. You might need to tighten the metal collar with pliers.1
