I am a noob in the world of Rakwireless and TTN. A while back I picked up a RAK7246G gateway and a few RAK811 nodes. As of yesterday everything is up and running; being able to connect and join the TTN. My goal is to have each node monitor several sensors and if the conditions are right, flip a relay. In addition, I would like to send the state and state changes of each system to the gateway. I know this isn’t rocket science, just a little GPIO and logic.
How do I do this:
- Use the serial tool and the configuration options
- Use the Application and Device settings on TTN
- Use a micro controller to drive the node via UART
- Use the node as a micro controller and code it up
Options 1-2 seem doable but I don’t know the system well enough.
Option 3 seems to waste the GPIO on the node since the micro controller will have GPIO
Seems like the right answer if option 1 or 2 won’t work.
Before I over engineer anything I would like a little guidance to get to the most elegant solution.
