I have a MQTT Mosquitto server running on a Raspberry Pi, and it receives local energy data every 5 seconds, along with other MQTT data - switches, environmental data etc. Currently, the same Pi processes the data in node-RED, and publishes it in a NR dashboard & Grafana. However, I've also setup …

Well I got there in the end!! TLS secure MQTT connection to another webserver, and all local network MQTT traffic not encrypted, so that I can easily connect to local sensors etc. It was surprisingly simple (but only when you know how :woozy_face:) If there's any interest, I'll write-up the proce…

I'm still failing miserably trying to get MQTT over websockets to work! I have 2 servers; https://mysite.co.uk & https://nodered.mysite.co.uk, one is on a local RP & the other a Oracle VM. Both have very simple flows; [flow] I have not setup TLS security for the websocket connection yet, and ther…

Where are you running the mqtt broker?

On https://mysite.co.uk but I can't see where the broker comes into play?

The MQTT nodes have to connect to the same broker, but you seem to have configured the nodes to connect to brokers on the opposite machine.

I thought that they were connected by websockets, not by the mqtt server? Sorry if I'm being a bit slow....

[image] Paul-Reed: 'm still failing miserably trying to get MQTT over websockets to work! IIRC - you have to stick the port number in the server name for some reason try using ws://nodered.mysite.co.uk:9001 (or whatever port your broker is using for websockets)

[image] Colin: The mqtt nodes don't talk directly to each other, each one talks to the broker Well if I set the server as ws://mysite.co.uk - which is the site containing the Mosquitto broker, it still does not connect. [image] cymplecy: try using ws://nodered.mysite.co.uk:9001 I trie…

Your broker won't be using 1883 for websockets - default mosquitto is to use 9001 but in this example, the broker uses 8080 [image]

PS have you configured your broker to use websockets? They don't tend to be pre-configured for them out-of-the-box

Websockets is an option for how the mqtt nodes connect to the broker, at least that is how I understood it. The mqtt nodes don't talk directly to each other, each one talks to the broker.
