Hi Olaf
I just checked some of my chart settings, and I do not define service="mysql"
in the chart item. Maybe try it without it?
This is my config for Temperature chart:
Frame {
Switch item=Temperature_Period icon="temperature2" label="Chart Period" mappings=[0="Day", 1="Week", 2="Two weeks"]
Chart item=Temperature period=D refresh=30000 visibility=[Temperature_Period==0]
Chart item=Temperature period=W refresh=300000 visibility=[Temperature_Period==1]
Chart item=Temperature period=2W refresh=300000 visibility=[Temperature_Period==2]}
}
On a side note:
I’m using persistence on my Synology as well. I have installed:
- Java8 8.0.101
- MariaDB 5.5.53 and
- phpMyAdmin 4.6.5
Persistence in OH2 is JDBC Persistence MariaDB 1.9.0
This works well for me to make charts. It might be worthwhile to check this setup.
