Number Entity seems not get updated from remote HA

[roverix]

Hello everybody,
I'm writing here for the first time, please excuse me if I will say something not pertinent.

I create an automation on the main Home assistant server.
The automation should trigger when the number of the Temperature entity, change over a value of 10.
The value is 23 but the automation trigger did't fire.
I don't understand if I miss something or is a bug.
In the configuration wizard I checked nearly every item, and no filter.
The communication between two servers are ok because I see the value updated in the lovelace.
What I should check?

Many thanks
