I honestly do not know what to think (not about your project / code I hasten to add).
Building Node-Red into a communications gateway seems 'odd' to me - not sure why but maybe it's my inner Linux creeping out - create a tool to do one job and do it well.
To have an industrial piece of kit that is running out of date software (Released 2021) is concerning esp with one that has wireless access (OK I do not know of any LoRa vulnerabilities but that does not mean they do not exist).
I can see the selling points:
- Pre-process the data before it hits the main network
- One box so less maintenance
- One supplier
but still bothered so I'll not surf their offerings I'm afraid.
