Is it possible to restore the values after changing something to a items file?
When I add a new or change an item in one of my .items file, all values are gone. Some of my rules don’t like this
I know I can manually add some lines to the rules to grab the values, but maybe there are other possibilities?
http://docs.openhab.org/configuration/persistence.html
Works for both OH startup and reload of .items files.
- restoreOnStartup: load and initialize the last persisted state of the Item on openHAB startup (if the Item state is undefined (UNDEF)).
Nothing is mentioned about reload of .items files… or do I miss something?
I also noticed that items with values ON or OFF are not restored.
maybe good to know: I use JDBC with Mariadb
Depending on the database Switch Items should also be restored. I have no experience with JDBC. I use MapDB for restoreOnStartup.
I was also thinking to use mapdb. Do you only add restoreOnStartup as strategy? And mapdb needs to be configured as default persistence, right?
Half right. I use restoreOnStartup for the strategy on *. MapDB does not need to be the default persistence.

Thanks, I’ll check this.
It seems t be working, but since I installed mapdb, my graphs are ony displaying a flat line. I checked my jdbc persistence (mariadb), and there are still new entries logged every 5 minutes.
But it looks like the charts are taking the mapdb data… I only removed the restoreOnStartup
strategy for my jdbc persistence
Text label="Graph" icon="line" {
Switch item=General_ChartPeriod label="Choose time period" mappings=[0="Hour", 1="Day", 2="Week", 3="Month", 4="Year"]
Chart item=Grp_Xiaomi_Temp_0 period=h refresh=600 visibility=[General_ChartPeriod==0]
Chart item=Grp_Xiaomi_Temp_0 period=D refresh=900 visibility=[General_ChartPeriod==1, General_ChartPeriod=="NULL"]
Chart item=Grp_Xiaomi_Temp_0 period=W refresh=3600 visibility=[General_ChartPeriod==2]
Chart item=Grp_Xiaomi_Temp_0 period=M refresh=3600 visibility=[General_ChartPeriod==3]
Chart item=Grp_Xiaomi_Temp_0 period=Y refresh=3600 visibility=[General_ChartPeriod==4]
Chart item=Grp_Xiaomi_Hum_0 period=h refresh=600 visibility=[General_ChartPeriod==0]
Chart item=Grp_Xiaomi_Hum_0 period=D refresh=900 visibility=[General_ChartPeriod==1, General_ChartPeriod=="NULL"]
Chart item=Grp_Xiaomi_Hum_0 period=W refresh=3600 visibility=[General_ChartPeriod==2]
Chart item=Grp_Xiaomi_Hum_0 period=M refresh=3600 visibility=[General_ChartPeriod==3]
Chart item=Grp_Xiaomi_Hum_0 period=Y refresh=3600 visibility=[General_ChartPeriod==4]
}
What is your default persistence? It sounds like it is trying to chart from MapDB which only keeps the most recent value so a flat line would be the result.
Make sure that jdbc is set as your default or add service="jdbc"
to your Charts
Chart item=Grp_Xiaomi_Temp_0 period=h refresh=600 service="jdbc" visibility=[General_ChartPeriod==0]
By adding service="jdbc"
to the chart item, the issue is solved.
jdbc is set as default in conf/services/runtime.cfg
& in the paper UI. I already restarted OpenHAB
