I've asked Jango the next information about this issue:

Can you send me the json result of: http://domoticz_ip:port/json.htm?type=devices&filter=all

And if you open the Domoticz in Firefox, then go to the screen where you see your usage.

• Hit F12 to open de developers console, and make sure the tab 'console' is open.
• Please send me the url that is now in the developers console like: "http://ip:port/json.htm?type=textlog&idx=198" or "http://ip:port/json.htm?type=graph&sensor=counter&method=1&idx=58&range=day"
• Please also send me the json for that url.
