I am trying to calculate the costs for one time washing with my washing machine.
I have no problem to detect start and and, the flows are available.
Für the start, I can set a logic or better logic numerical variable with the meter reading.
However for both, logic and better logic, I don’t succeed defining the calculation. I don’t see, how to calculate with a variable. They don’t show up at the tags, also $variable$ and the like does not work.
I have searched the forum - found nothing.
Also, how do I use the result in a text message to push or simple log? I only see Boolean variables to chose from?
Nay help would be appreciated!
(Please not only screenshots, which don’t show me how to get this!)
