[Solved] Tuya Smart - How to program a cyclic action every 20 minutes at < 7°C?

How do I get a cyclical action in Tuya every 20 minutes?
I would like it to :
A. when the outside temp drops below 7 degrees
B. a contactor (OXT relay) would cycle on for 40 seconds every 20 minutes
C. when it jumps above 7 degrees - switch off B.
Is it possible to program the SCENE in Tuya Smart in this way ?

I think it is possible. You would have to buy a blu or wifi thermometer, a gate and your socket. Together you add them to the gate and then maybe there you can set up such scenes. I have a BLU thermometer in the room and when my temperature drops below 10C it turns on the central heating furnace.
Maybe someone more familiar with the subject can advise you.

Thermometer I have; gated. The relay too.
I just don't know how to get that cyclicity in Tuya.

This is how I programmed it and it works:

1. (when any condition is met)
1a if relay is OFF
1b if temp outside < 7

2a. delay the action 20 min
2b. set the relay to ON
2c. set the relay contdown to 40 sec.

3. preconditions: outside temp < 7

It works like this:

The script starts when the relay switches off or the temp drops below 7 deg C. Then: it waits 20 min, then switches the relay on for 40 sec, after which it starts again (because the relay is off), i.e.: it waits 20 min, then switches the relay on for 40 sec, etc. ...
The script will run in a loop as long as the outside temp<7 deg C ( preconditions ).
