by migrating from OH 2.5 to OH 3 i tried to use the new charting possibilities, looks great and also analyze i single item and save is really great!
but it does not work with all items.
as datawarehouse i’m using influxdb version 1.8
as i could see so far, analyze is working with items with 2 decimal places, where ever they come from
and not working in case of no decimal places …
it seem to be an influxdb related issue … the query for SMAEnergyMeter_BezogeneLeistung works…
ReturnCode 200

any ideas ?
i seems that influxdb query does not like the unescaped item names starting with a number
Well spotted; Item names should not start with a number
openHAB validation currently misses this
oh, it’s such a long time ago where i read about item naming… i just let them start with an underscore… are there any known limitations to that ?
