I want to be able to receive water meter readings using a DIY gateway that has LoRaWAN module interfaced with Raspberry Pi. Is there any standard that LoRaWAN water meters follow to send the readings or is it completely proprietary?
I tried to google but found no luck.
Thanks and Regards,
Goldy
You should improve your search (re-)skillz, see: This guide can help you build your own LoRaWAN gateway using a Raspberry Pi , but your question does not contain details about the chip used.
