amenhotep19/librato-esp8266

A temperature sensor based on esp8266 and nodemcu

Project

Here you should have everything you need to quickly prototype a temperature and humidity sensor based on the esp8266 and the nodemcu firmware. We will persist the measurements using librato as a backend.

Hardware

• Adafruit's esp8266 reakout
• Bread board
• Jumper wires
• power adaptor or batteries
• dht11 temperature and humidity sensor

This directory contains the necessary software to flash the chip
with nodemcu. If you want to build your own firmware you
can do it [locally](https://hub.docker.com/r/marcelstoer/nodemcu-build/)
or use this online [tool](http://nodemcu-build.com/).

We will use the luatool to send our lua scripts to the chip. One of
the scripts uses [statsd](https://github.com/etsy/statsd) to aggregate
and send data to librato. The other version uses a custom made proxy
in python that supports payload signing.

This is the python proxy I was referring to above.

This is an example configuration for statsd.
