Im trying to get things going

domotiga@domosmurf:~/domotiga/rrd$ chmod 777 graphs/ -R

If you click on climate page please copy the debug log output it generates here...
What you also can do is copy the whole line starting with/from rrdtool graph.... as it appears in the log window and paste it into a linux terminal window to be run outside of domotiga and see what it does...

I have enabled a device and added it to the climate group. After that i can click climate and see a graph with nan legends

But there is no rrrdtool / command in the debug logfile or in the graph screen so what am i missing ?

Maybe you see an old image, clear the graphs dir.
nan means not enough data gathered yet, or data out of range.
Then enable rrdtool debug open climate tab and see what it says.
Post it.
It should say no graphs found for climate group or it should note some rrdtool commands.
I have to guess too much this way.

It seems like graphing is working after adding the device to the climate group. Why does a device must be part of the climate group for graphing to work. The device has already graphing enabled

You must add a device to a group so DomotiGa knows on which page to show it.
Climate, Energy, etc...
Same for extended graphs.
Or did I overlook something? Or is something not logical?
I would be happy to change it if needed.

Ron,

any clues?

Carlos

Update:

Today i realize something very strange.

My domotiga server is located at /home/cmr/domotiga on a ARM machine

I ran my client on virtualbox located at /home/domotiga/domotiga on Windows

RRD files are updated on server but If you look at the image file attached RRDTOOL is trying to create graphs on the client's directory.

That's why i can't see no graphs on climate tab.

Ron? What should i do?

Carlos!!!!
