I've seen an example of a dynamic configuration here but I wonder if the MQTT Client ID can also be set dynamically. I want each device to set their ID to the device's serial number, so doing that manually across all devices is not a good solution. Is that possible?

@Steve-Mcl Great, thanks for the quick help! One more follow-up question: Can the TLS configuration also be set dynamically?

[image] NNNN: Can the TLS configuration also be set dynamically No. not supported. You can use ENV VARs in the TLS config (env vars get evaluated at launch of node-red) - perhaps that would help?
