Establish mosquitto MQTT over websockets

[mohamed Abdulmajid]

Hello everyone, 

i have a raspberry pi that runs raspbian with mosquitto, node red, influx db, and grafana installed. i'd like to use grafana to control a sonoff switch through mqtt and i have found this panel geeks-r-us mqtt grafana panel. but unfortunately, due to the panel runs in the browser it can only establish mqtt connection over websockets. i tried to modify the mosquitto.conf file but it doesn't work. 

could anyone help me to establish this connection and get it work ?
