ESP8266

We use these in our new ESP8266 Sensor Server but will make more generic programming notes here.

The ESP8266 is a low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller capability produced by Shanghai-based manufacturer Espressif. wikipedia

We generate sensor reports from flat files maintained within the SensorServer system with the mksensor script.
