• Hi, the date must be converted to the decimal format before the mathematical operation and back to time format.

• Hi,

no funktion in my example!

• @jens timeDecimal only works for time of day strings and thus cannot be used to calculate date offsets.

Thank you.

• Hi Jens,

How did you make the gauges?
Or is that an iframe? In that case, how do you update them to see actual info?

Hi, this is my way.

I have 3 Variable in my system.

``````\$wasserfilter
\$wasserfilter 2
\$wasserdatum
``````

and 2 Rules.

``````When Reset is pressed set \$wasserfilter = 182 and set \$wasserfilter2 = 1 and set \$wasserdatum to \$system-date.date
When its after 0:00 hour set \$wasserfilter to \$wasserfilter - 1 and set \$wasserfilter2 to \$wasserfilter2 + 1
``````

“182” is the half year.

A Variable Device with \$wasserdatum and \$wasserfilter and Gauge Device with \$wasserfilter 2 and \$wasserfilter show the information.
A Button Device with “confirm enabled” for set and reset funktion.

Good night!

• @jens Thanks for the reply. In your case it might be OK, but if Pimatic is off around midnight counts will be lost. I am still looking for a solution where I store the start date and calculate the elapsed time when ever is needed.

• Hi,
