Hi @wes.johnson ,
- I am not sure on the type of the MQTT server implementation (let me get back on this), but it is deployed on a google cloud.
- It does support MQTT v3.1.1 as I have published to the broker via node red mqtt node via MQTTv3.1.1
- It is using basic authentication which is username and password.
So there is an update on the mqtt transmission module for ignition 8.3, I have been using mqtt transmission for ignition without the version for the past few day to search for help.
Anyway, deeply appreciate for this link and thanks!
