i spent lots of time using this pluggin without success.
i have configured Grafana behind a proxy server, all seems to work fine.
i have added the mqtt plugin and connected it to my MQTT server. (connection ok)
i added 3 panels with each 1 topic
but when i load the dashboard, the value are displayed randomly..
sometimes, only 1 value, sometimes, 2 values, most of the time, all 3 panels display "no data".
if let google chrome opened on the dashboard and restart grafana-server, the 3 values instantly refresh with values !
that seems to confirm the proxy server is working fine.
note these 3 topics are only refreshed once per day.
another thing to notice, if i use the "explore" feature and set 1 topic, i get values, but only when new mqtt value... (but graph display only 1st point)
i also checked the log files, but there is no error shown
it is like mqtt plugin do not always send the latest value before streaming new one..
