i think you are over complicating your life… It also sounds as if you have everything running on the pi?
You either need to:
- develop something against the API (your chirpstack ip/API)
- Use a excel to API → Lora App Server new device registration - #12 by fmgst
- Simply show the customer how to do it in the AS.
I would however not really look to run this all on a RPI… SD cards are not realy meant for this. You either need to get your own version of Chirpstack running in the cloud and then give him an account, or build a sull appliance install for him…
But running everything on an RPI is only going to cause you headaches…
