Chart issues IOS, works in basic ui

  • Platform information:

    • openHAB version:3.0.1

Im trying to get the chart functionality to work in the ios openhab app.
I have my chart defined in my sitemap as per:
Chart item=Lounge_Temps label=“Internal Temperature” refresh=600 period=D legend=false
Where lounge temps is a group of temperatures.

This works fine in basic ui, but will not show up in the ios app.

If i remove one item, from the list (the setpoint temperature) it works correctly.
the only difference i can see between the ones that work and dont, is the category, the ones that work are temperature whereas the ones that don’t work are categorised as heating.

However if i then change this to :temperature on the ones that do not work, it still does not resolve the issue.
Is there anyway i can see exactly the differences between two items?
