Please explain the context of the problem you are running into (and don't try to put everything in the subject).
We don't know what you mean with "contact" and "activated" etc.

Calculate how long a relay is activated during the day, if it is activated more than two hours a day, we send a condition to the flow so that it is not activated until the next day

So, you want to calculate cumulative time the relay is on activated position, and need not be continuously activated and reset after a day and start over again ?
