i created a new item, wrote to it like the debugItem in my post before but sadly everything looks the same… in a chart it shows 0.38% instead of 38%.
I think the item is good so far as i can see in the events.log but the graph isn’t. Any further idea?
Edit: i found the same question here: Charts in OH3 - #27 by VPrimus
Edit2: The solution is, not to use %unit% but hardcode it to “%%” - Then the chart is correct.
Thanks anyway for getting me through this!
