Do I need a smart thermostate when using smart thermostatic valve controllers?

Hey all! I am looking for some advice. I want to buy several of those shelly TRVs to manage the heating in my house but I was wondering, I probably also need a smart thermostat in order to really have this working correctly, am I right?

I live in The Netherlands, I only have heaters (no floor heating).

Reason I am asking this is that the main thermostate has to give the signal for the boiler(?) to heat up. I can open up all my valves but if the boiler isn't delivering hot water then it's basically for nothing, right?

Well by default all it does is open and close the valves just as your normal ones would do

Heating would continue to be enabled on exactly the same reasoning as it does without

Well the thing is that I currently have a "dumb" thermostate that measures the temperature in my living room and sends a signal to the boiler to heat up or not.

Then depending on the valves per room it would heat up.

Now I was thinking if, when getting these TRVs, I needed to also replace this "dumb" thermo with a smarter version. So for example it wouldn't already send the signal to my boiler that we are done heating (temperature in living room is as desired) while the temperature in my study hasn't.

I see what you mean, in that case yes it could help controlling that differently. But it mostly would require multiple temp sensors

In more theory you may be able to use the sensors on those valves

That's what I thought too. But luckily I have several temp sensors already

So I can combine those
