[doku] can you provide an example for Node-Red

[Hypnos3]

I was not able to get a mqtt connection of gbridge with node-red.

To rule out whether this is a local problem, it would be nice if someone could point out an example of a working node-red configuration that you might also be able to include in the documentation.

My (not working) configuration is:
TLS:

MQTT 1:

MQTT 2:

Many Thanks

I don't use NodeRed regularly, so I would write examples blindly.

Try:

• Removing the "CA Certificate" (thus leaving it empty)
• Checking "Verify server certificate"
• Checking "Use legacy MQTT 3.1 support"

This configuration worked for some users who requested support and for me in a test environment.

Have a good one!

[peterkappelt]

Have you got it working with these recommendations?

[Hypnos3]

No, same Problem.

I try my self hosted docker instance.

I wouldn't like to close this issue yet. I don't really know wheter this problem just exists for you or for all NodeRed users.

It did work for a couple of NodeRed users around two months ago. It is possible that an update of NodeRed somehow broke the compatibility with gBridge's MQTT servers

Can you give additional information? Are there any log files? What's the exact problem (Is your NodeRed instance unable to make a connection to gBridge? Do you receive no messages? ...)

Best regards,

the only error is:

Hi, For me it works without TLS configuration. Just enable secure connection, but don't add anything in the configuration.

I had similar connection problems, but solved it by changing the MQTT password as mine had a $ character which was causing authentication error. Mine works with TLS enabled but not configured. gBridge is great, thanks!

[Hypnos3]

Thank you!! This was the problem. I Have the # sign in the password. I have changed this and now it is working.

[peterkappelt]

Ahh, that was too easy...

I've wrote a guide for Node-RED integration: https://doc.gbridge.io/integration/tasmota.html
