Temperature flow

I feel kind of stupid, but I can’t create a flow to control a floor valve. I bought a Tado smart thermostat. I want the flow to open the valve when the temperature is lower than the set value of the thermostat. How do I make the flow?

I think a clarification is needed. It is a wall thermostat. I want to turn a smart plug on and off depending the set temperature value and the actual temperature. (The smart plug turns on and off a valve for floor heating.) I cannot find any relevant flow tag for this. Please help me.

Create a number-variable ‘target temperature’

WHEN
Temperature has changed
AND
Temperature is less then ‘target temperature’
(Logic-card)
THEN
open valve
ELSE
Close valve

Thank you very much. I will try this.

Or even better, two flows. One for opening the valve and another with a slightly higher target temperature for closing. This way the valve will not be going back and forth a lot if the temperature is fluctuating around the target temperature.

I don’t understand. These are the tags that I get when I choose Tado’s thermostat.
(I have translated tags from Swedish. Maybe it’s not correct.)
Battery alarm …
Humidity …
TEMPERATURE IS BETWEEN … AND …
Open window …
Is on
Smart Schedule is activated
THE TARGET TEMPERATURE IS BETWEEN … AND …

Are these WHEN or AND tags ?

‘TEMPERATURE IS BETWEEN … AND …’ sounds like AND (requirement) and not an WHEN (Trigger/event)..

Thank you all. I have to leave the summerhouse now. Will make another try next time. Probably I have to by an other wall thermostat.

Maybe you can tell which type of Tado thermostat and which app you are using?
So we can see by ourselves which cards are available.

I bought a kit:
Tado Smart Thermostat StarterKit V3+

I could not find what type of roomthermostat is included in the package.
So it is not clear which app does support this thermostat.
