Hello, my charts stopped working after a previous openhab update, but i dont know which.
The picture is there but the value is still the same, so its not creating a curve, only a horizontal line.
Confirm you do see different values when using the call to the REST API.
Does the chart display the current value as a horizontal line?
Does a chart displayed via a Habpanel widget show correctly?
I have seen such behaviour after moving from a SSD based system go a SD card based one (new image of openhabian and saved config and .rrd files copied over). Since then after each restart on the raspi I had to clean the cache, restart openHAB and then manually restart all bundles that remained in “resolved” to get a back to a working system.
I have NO idea what is causing this.
