Hi
I'm trying to figure out how long during a day my water heater is working.
i've figure out how to use the time-difference function in LUA but i can't seem to aggregate the differences to a total amount.

from what i know the scripts run every minute by domoticz, and inside the script there's no variable who can keep the information without it getting written-over. I've tried using user variables but those too didn't kept the information.

is there a place or a way to create variables "above" the scripts? something that will keep the information?
