When following the documentation to insert charts into sitemaps, I am running into some trouble regarding groups.
The group Temperature_Living contains multiple temperature sensors. All sensor values AND the value of the group itself, are persisted every minute and on every change.
Group:Number:AVG Temperature_Living "Temperatur (Stue) [%.1f °C]" <temperature> (Temperature_Inside, Temperature_Inside_MIN, Temperature_Inside_MAX)
Chart item=Temperature_Living refresh=60 period=W
The above generates a chart, with a series (line) for EACH for the sensors in the group. The generated URL for the image is as follows:
Instead of a line for each sensor in the group, I would like to get a single line, showing the group itself. I can do this because I also persist the value of the group itself, and if the URL is changed to the below, it works fine (Changed groups= to items= ):
Unfortunately I cannot decide in the sitemap configuration if I want the group items or the group itself to be shown in the chart. Or does anyone know a way to do this?
