LoRaWAN QR scanner

LoRaWAN LHT65N temperature sensors

We have our own iotaaap LNS, and for a while we were doing device configurations manually.

Now I quickly built a Node.js app to speed things up. I just scan a QR code, and it automatically fills the database with the keys I need. It also generates a file I can directly send to our partners, so they can easily pair devices with the DHM app out in the field.

It took me 18 minutes to build it. And yes, ChatGPT wrote most of the code. Now it saves me at least 8 minutes per device every time I need to configure and add one to the platform.

Small tool, big difference. We're deploying 40 devices per user, on average!
