Good afternoon all,
I would like to calculate the amount of time that a dummy variable has the value 'on'.
I suspect that using the user readings option, but I'm a bit stuck. I've had a few attempts but nothing has worked too well.
any help appreciated.
Andrew
I think you are looking for the HourCounter (http://fhem.de/commandref.html#HourCounter) module.
Fantastic, thank you.
I've been using them for a couple of years now, and spent a long time with it over that period, but so much has been added recently that i've missed a lot of the new features.
