I succesfully linked HA with google assistant, but i have problems about which commands to send to Assistant regarding climate sensors. I created three generic climate sensors for my three temperature sensors, they are recognized by Google but i really don’t know how to call them to tell me the actual temperature…
More, which is the command to send for having TADO climate temperature?
Hey Maurizio, long time no see 
As far as I know (unless recently changed) you can no longer “fake” a temperature sensor into a thermostat for Google Assistant (GA) since 0.65.6:
Google Assistant integration: It is no longer possible to override the domain that Home Assistant uses for an entity. This was bound to go wrong when we would test supported features for different domains. Also removed support for disguising temperature sensors as thermostats. We should follow the traits that Google offer us and not offer things that will only work half. (@balloob - #12959) (google_assistant docs) (light docs) (breaking change)
Now 0.65.6 is a while back and there’s been lot of improvements in GA side so things might have changed…
Are you sure of this? trying many commands i get the response about one of my temperature sensors, but the strange is that it worked only for one sensor and only one time and i forgot what command i used…
No I’m not sure 
And since my thermostat is a Nest it integrated automatically…
Just asked google “what is the temperature on my thermostat” and it gave me both current and set temps…
I do the same with my Tado thermostat.
