Hivemq cloud connection

[ivangilli]

Is it possible to connect with the hivemq cloud mqtt service? Currently not...

[barbudor]

Yes it is
You need a build with mqtt-tls enabled which is not by default for esp8266 but is for esp32

This has been addressed multiple times in discussions in the past, please search

Actually you don't need to create a username/password
Leaving that blank also works fine

Indeed the cluster URL is a token which is private to your account.
Creating client credentials would allow, for example, to create access rules to topics based on client

How can I show this window with optional features??

[barbudor]

This is the standard MQTT Broker configuration for the current development version
You must pull the development branch from GitHub and run it in Python.
TLS is (AFAIK) not available in binary release

@jziolkowski @Jason2866 Would it be possible to update PyPi and binary release to the latest development version ?

Thanks

Where is the configura file on Mac?

[ivangilli]

I was able to make the program work on Mac too...I had to edit the mqtt.py management file
