Hey! I have project on sea, around 300 - 500 buoys. Every buoy needs it’s own node and there would be gateway on the coast… (300 - 600m no obstacles or just here and there a boat)
I need to send small amounts of data to my web server (so not using things network…).
For example I would have web site running on my machine at home, and when you click on specific button, it would trigger that buoy would send few floats to my web page.
I was thinking like this (feel free to suggest better way of doing it):
-Raspberry Pi 3 with RAK831 for gateway, raspberry would have USB modem for internet
-Every buoy node
Problems and questions:
-Single point of failure
-What Node or Gateway to use?
