Basic http end-point on RIO

[Beno]

You are going to hit brick wall after brick wall using the stock HTTP IN node because the port it listens on can not be changed.
This thread talks about this here:

Node Red HTTP IN Node Post Endpoint

I have a node red flow that uses an HTTP In node to create an endpoint to accept data from other devices. It parses the data and put it into the Epic’s MariaDB. I am testing it using Postman (https://www.postman.com/). When I am inside my network I use the local IP address of the Epic (note no port specified). It works. Here is the post command I use in Postman: https://10.1.5.101/node-red/test?signalin=7.54&eventdatetime=2021-04-17 13:52:58&unitid=21477&channel=1 When I am outside my net…

(Stop reading when it gets into the certificate stuff - or not).

So it all depends on what your end goal is here.
The TCP In node might be the better better tool as you can change it to listen to a port above 1024 and then open the groov firewall to match the port number and you will be up and running to some extent.
