I’d say that’s another website that we as Corporal Hicks would say, need to nuke from high orbit.
It’s old stuff. Very very old stuff. It would create something called a SCPF - I can’t use the whole name as it’s worse than saying Voldermort or other swear words. I mean really bad. Makes Samuel L. Jackson in Pulp Fiction with his Oedipal Noun phrase look like saintly language.
You won’t even get started, far too many complications - and you won’t get ANY support from any of us on here. See this for more info: Single Channel Packet Forwarders (SCPF) are obsolete and not supported
You need to remove the word ‘assume’ from your LoRaWAN vocabulary - it’s got too many moving parts to assume anything. Which is why we are so happy to help with sensible questions, even if we do get a bit theatric (like above) with some of the answers.
If you need a solid starter gateway, get a TTIG, a Dragino LPS8 or LIG16 or a RAK card to sit on top of your Pi - they are all reasonably priced (for the technology) and are all fully compliant.
Going penny-pinching cheap is a real bad move with LoRaWAN - as you end up buying stuff you can’t use and no one can help you make work because it’s just not possible.
Once you have got going with creating a device, you can bring the cost down in that dept, you can build one for around £/$/€10 with a sensor or two. But to get started you need something you can rely on and is on the support list, like the Feather above.
