Thanks to all of you for your answers,
I started to insert a lot of automations to take over my previous “assistants” Smart Things etc., but I see that something doesn’t work with Home Assistant.
In order to let the automation work I have to execut it manually … but in real life of course it doesn’t make sense.
This is the simpler automation I tryed and … of course it doesn’t start:
alias: prova
description: ""
triggers:
- type: turned_off
device_id: ac31ec94c5b79d510a7c947668a6de35

- condition: time

actions:
- type: turn_on

entity_id: ec1f158ced38243afa548776abf60920
domain: light
- delay:
hours: 0
minutes: 0
seconds: 30
milliseconds: 0
- type: turn_off
device_id: ac31ec94c5b79d510a7c947668a6de35
entity_id: ec1f158ced38243afa548776abf60920
domain: light
mode: single
… so in the end at 10:05 nor at 10:06 the light didn’t switch on …
About logs … yes, I see a lot of lines there, but nothing for example regarding the trial above … maybe it was too easy for the system to be considered 
What can I try?
I was also considering that (maybe) the rule from my router to switch to different IP’s users within the home network on itself whenever considered necessary (in other words the system doesn’t work based on ‘static’ IP’s) could be a (or the) problem.
From the other side I’m warried that if I remove this setting (suggested by TP-LINK) on my router I risk to lose the connection with some device.
One of the log errors I see maybe connected to some automation is this:

Briefly some automation contains conditions like a temperature value from a room, coming from the air conditioner temperature sensor in that room, in order to start (or not) another heating system.
Now, the air conditioner is always on stby by night and well connected to the wifi so it can provide the temperature data, but then why Home Assistant doesn’t complete the automation?
By the way, considering I’m new on all of this system I can even be wrong and misunderstanding logs and their meanings.
I’m a bit discouraged on this stuff
