MQTT node in NodeRed


I’m trying to use the MQTT OUT node in Node-Red to post some data to your MQTT broker.
The TLS confit for the broker are as screenshot below. Which option should I pick and where can I get the needed certificate?


Hi Lars,

The CA Certificate can be found here!

Additionally, there is some MQTT documentation that details a little more about certificates, and a blog post on using Node RED as a gateway, which has some helpful tips.

Let me know if this helps,
