Connectivity

The firmware only sensor readout and conditioning on the data, and then transmit it over WiFi/MQTT. Data logging and processing is done using MsgFlo components on the message queue.

Basic idea is to:

The MsgFlo side of this integration is in the c-flo repository.

MQTT connectivity is handled by the MicroFlo ESP8266 MsgFlo integration.
