TODO
-
tls
-
change hard-coded device id
- DS18B20 - connect to the board to provide a unique id
-
ability for user to change telemetry reporting interval
-
Once the hardware is somewhere near being finalized, a qr-code with the device id can be put on the housing. This will allow the app to scan it and add it.
-
Set the device hosts/hostname to the device id for easy network identification
-
Need a way to do user setup on the device to connect it to wifi.
- Start the device as an AP with a webpage that the user can log into and change settings via wifi?
