Graphs not displayed on App

Apps & Services Android App
1

Hi,
I’ve configured three graphs for my temperature sensors and they are diplayed regulary if I access to openhab with a browser.Insted when I use the android app usually no graphs are displayed or they are displayed partially (only one of three) or they are displayed after a lot of time (5 minutes after the apps in loaded)
Sitemaps configuration is the following:
Frame label=“Temp. Room1” {
Chart item=Fibaro_Motion_1_1_Temperature period=d refresh=3000
}
Frame label=“Temp. Room2” {
Chart item=Fibaro_Motion_2_1_Temperature period=d refresh=3000
}
Frame label=“Temp. Room3” {
Chart item=Fibaro_Motion_3_1_Temperature period=d refresh=3000
}

If I check jetty request log while accessing with the app It seems that the app try to access to the graphs many times:

As you can see the http response code is 200 and no error are presents in openhab.log, It seems that the app continuos retry to get the graph image.
Instead when I access to openhab with browser I see only three get for my three graps:

Any clues ?

Can you increase refresh? I think there is no point it trying to refresh charts every 3 seconds.

Yes you were right!
Increasing the refresh time solved my problem.
Thanx!

using latest Openhab Beta 4 and Habdroid App, the Chart is showing no items (actual Chart is displayed, but not items and only 0 to the left).

While displays perfectly on the Web interface, any ideas ?

5

i found out that single item on chart would work, not the group chart though, any ideas ?

I had the same issue. A chart was displaying fine in BasicUI and ClassicUI but did not show up in HABDroid. After playiing around I found the wrapping the Chart definition in a frame caused the problem.
Using this in my sitemap was NOT working:

     Frame label="Temperaturverlauf" {
      Chart label="TempChart1" item=Temperature4 period=2W refresh=30000 service=rrd4j
    }

By removing the frame, the exactly identical chart definition worked well:

      Chart label="TempChart1" item=Temperature4 period=2W refresh=30000 service=rrd4j
