Execute automation with delay between 2 actions

Hello, i have integrated stores control in my HA:

I would like to create an automation which closes all the stores in this room.
However the dues to a technical reasons it is not working if i send immediately a close action to Store 1 and Store 2, i need to do the following:
Store 1 close
Wait 3 sec
Store 2 close
The problem is related in the fact that the device is not able to queue the commands, and when a radio channel is occupied, it ignores the second order, so i need to add a delay between actions.
I have played with timers, but i think i am doing it wrong:

What would be the best way to achive this scenario ?
Thank you

Use a delay (wait for time to pass) instead of the timer.
Timers will just run in the background

Thank you it worked!
