[chbot] IoT, ESP8266,Node-RED, etc.

[Mark Atherton]

Hi All,

A week or so ago, Richard published some notes on his adventures with 
the ESP8266, and a project published by Martin Harizanov

http://harizanov.com/2015/02/wifi-thermostat-with-weekly-scheduler/

On the surface, this looks like a straightforward project, but digging 
further reveals that this guy has done a huge amount of work, and 
created quite a framework, of which the 
wifi-thermostat-with-weekly-scheduler appears to be just a single component.

Martin also published a Google hangout session talking about the project 
: https://www.youtube.com/watch?v=KPnwyTgZaS0

.... part of which is system level configuration using nodeRED (see 25:46 
into the video)

So onto http://nodered.org/
     Node-RED: A visual tool for wiring the Internet of Things,
     Node-RED is a tool for wiring together hardware devices, APIs and 
online services in new and interesting ways.

Martin has chosen MQTT as TCP messaging protocol of choice
     MQTT is a publish-subscribe based "light weight" messaging protocol 
for use on top of the TCP/IP protocol.
     It is designed for connections with remote locations where a "small 
code footprint" is required and/or network bandwidth is limited.

So, it looks like with a bit of careful planning, it is possible to 
create quite a comprehensive and well documented IoT network using low 
cost hardware and free software
