I have an odd problem where charts are a flat line based on whatever the last value opened. So if temp is currently 77.8 I will see a line all day or week at 77.8, but if it changes to 80, the line will be 80.
Now, if I restart openhab for about 10 seconds or so after a restart my charts work fine, then the go back to the flat line for the value. This is for all charts, on my system. Any ideas how to debug this?
What have you set as a default persistence service?
Did youcheck if there are really different values stores in the used persistence ( rrd4j or MySQL)?
Yes, the values are different in both rrd4j and MySQL and if I restart openhab the graphs are generated correctly for about 10 seconds or so, then they go flat lines but always updating to the current value.
