Hello,
i want to show the maximum, the minimum & the average temperatur of the year in my chart. But i have no idea or found a topic wich item i need.

Currently I let me show the current temperature. Does anyone have an idea or know what I mean?

In order to show such calculated values you need to create items that take those values and calculate them periodically.

There is some limited ability to add such functions to charts. See the docs:

And try searching the formus for examples using aggregationFunction

You can also do this with the analyze function…
There are options for min, max and average.
Just set the time period to year, no need for an extra item or coding.

Thanks guys, my idea was to show this in HABPanel. But with the new OH3 UI it works so much easier. Thanks for help.
