OK, it's beginning to become clear. My initial gadgets & gizmos should arrive today, so I'll start tinkering, and I'm sure more clarity will come.
Thanks for the quick responses, and for your patience. This is so far the best HA forum I've found anywhere!

On the same way, i dont understand how and where are stored the values inside the gateway if not used on each reception, are they stored somewhere to be able to answer them when serial request arrive?
You could bypass this on some kind of events obviously !
Actually my perl gateway is acting as the server Vera is for the arduino gateway. So from there I can trigger external URL, store data in a sqlite3 database... and so on !
For those of you who want an extremely simple build, I've reduced it to just 5 parts:
one 1-megaohm resistor (0805 SMD)
one Arduino Pro Mini
one Ra-01 LoRa module
Male header pins
Battery clips
See photos.
