We are looking at building a LoRa device that can send and receive data for monitoring of sensors and turning on solenoids via relays etc. The Pycom LoPy4 looks suitable.
Are there example micropython sketches that work with AU915 OTTA connecting to TTN that I can modify to achieve the uplink/downlink communications for device monitoring and actuation?
What we want to build is many devices that would be enclosed in an IP68 box that has something like:
Expansion board 3.1
Ability to be charge from solar panels
Downlink commands would be sent from our cloud platform via TTN to the device. The code on the device would decode the command and turn on/off GPIOs. The device would also monitor analog pins to uplink sensor data in mV etc. It would probably need to be LoRa class C.
Any advice regarding programability of the LoPy4 or alternative devices appreciated.
