The room thermostat sends its status if the room temperature has changed by more than 0.5°C since the last transmission. However, after 1h at the latest, it will be sent in any case (even if the temperature has changed less than 0.5°C).
The timestamp in the HomePilot is only adjusted for changes of more than 0.5°C. This means that if the temperature in the room does not vary by more than 0.5°C over 2 days, the last update in the HomePilot is correspondingly 2 days old.
In the case of automation via the HomePilot, of course, is immediately sent to the HomePilot when the temperature exceeds or falls below the set limits.
