Hello, I have some questions on Chats under OH2.
I transfered the Chartdefinition from OH1 to OH2:
Switch item=Heizung_Temp_System_Period label=“Heizung System” mappings=[0=“Stunde”, 1=“Tag”, 2=“Woche”, 3=“Monat”, 4=“Jahr”]
Chart item=Heizung_Temp_System period=h refresh=600000 visibility=[Heizung_Temp_System_Period==0]
Chart item=Heizung_Temp_System period=D refresh=12000000 visibility=[Heizung_Temp_System_Period==1, Heizung_Temp_System_Period==“Uninitialized”]
Chart item=Heizung_Temp_System period=W refresh=12000000 visibility=[Heizung_Temp_System_Period==2]
Chart item=Heizung_Temp_System period=M refresh=12000000 visibility=[Heizung_Temp_System_Period==3]
Chart item=Heizung_Temp_System period=Y refresh=12000000 visibility=[Heizung_Temp_System_Period==4]
They are working “sometimes”, means they appear sometime, sometimes not. If not, CPU usage goes to 100% (RPI3) and stays there for hours until the Browser is closed again.
The log shows then some tens gigabyte with:
2016-11-20 19:31:49.030 [WARN ] [eclipse.jetty.servlet.ServletHandler] - /chart
javax.imageio.IIOException: Can’t create output stream!
and:
2016-11-20 19:31:49.023 [WARN ] [eclipse.jetty.server.ServerConnector] -
java.io.IOException: Zu viele offene Dateien (to many open files)
and:
Caused by: javax.imageio.IIOException: Can’t create cache file!
What is wrong there? I tried to exchange the “Uninitialized” by
"NULL" and also by NULL (without quotes). No success.
Second Question: When I use habmin2 I can:
Diagramm-Editor --> choose the item to be displayed -> nice Diagramm is almost displayed on the spot.
Save --> give it a name --> choose some other stuff --> Green popup: saved O.K.
But now, where is it? How can I use it within OH2?
Nearly the same with the Dasboard. How can I use the saved Dash?
I googled the whole day, I need a hint where to find a liitle more info…
Thanks!
