Hi all, a long time ago some problem started to appear on my mobile and tablet, it doesn´t display any of my charts, Im using MYSQL. But, in web browser charts work like a charm. Can u help me with it ?

Here is my item line :
Number Temperature "Temperature [%.1f °C]" <temperature> (WeatherChart) { mqtt="<[mymosquitto:desktop/temperature:state:default]" }

And here is my sitemap line :

Chart item=Temperature period=D service="mysql" refresh=600

Using openhab 1.8.1

Please try to set a lower refresh frequency, currently set to 0.6 secs (refresh time is in msec)
