Software for a plant status reporting device.

Setup to compile software to run on a Wemos D1 Mini board to send Chirp sensor metrics to Azure IoT hub.

Script setup/macos.sh contains commands to install everything necessary to build and install this software from a MacOS machine.

1. Install software on the device as usual with Arduino/Wemos.
2. Device led should blink 10 times in 5 seconds to notify that configuration is starting.
3. Wait 6 minutes while the device creates a filesystem on first install.
4. Join WLAN named DEVICE_SETUP.
5. If a dialog doesn't open up, open browser and go to any address, eg. http://set.up/
6. Fill in requested information
   • name and password of the WLAN to use for access to Internet
   • address of MQTT server for uploading the metrics.
7. Device led blinks 10 times in 1 second to notify that the device has been configured.
8. Device led blinks once per second when it works normally.

You can listen in on the serial port for debug messages.

• Send a one-letter message to get configuration report.
• Send a JSON object to update configuration
  • "mqtt_server_url": an unused string for now
