cloudMQTT
Posted: 09:44, 04 Dec 2015
Hi
I have built a single website page that uses the js plugin "mqttws31.js" to get MQTT messages from cloudMQTT and display them in a webpage. The following html code perfectly in chrome but when running in evothings it won't connect to the server.
I get the following error through evothings console log
LOG: used for debugging
LOG: [object Object]
LOG: error
attached is the following html file
Thanks
Steve
