Hi and Welcome to Steve’s Internet Guide.

The first wave of the Internet involved connecting people to each other and people to information.

The next wave of the Internet will involve connecting the physical world to the Internet, and machines to each other (M2M – Machine to machine).

Although the Internet of Things will make use of the existing Internet and Internet technologies t will introduce new technologies,protocols and services.

One of the protocols I believe will be crucial in the coming years is MQTT and it will form the main focus of this site.

The node-red http request node is a core node and can be used for making http requests. It can be used for.

• Retrieving web pages from a website
• Making API Request
• Sending and receiving JSON data to a website or API.
• etc

This is a data and topic logger similar to the python data and topic loggers that can be used for logging MQTT data to log files either as a single file containing multiple topics or multiple files based on topic.

It is controlled using a node-red dashboard making it much easier to use than the python loggers. (more…)

The MQTT data logger logs data to all monitored topics to the same log files.

If the data need to be split into topics then it will need to be done by the log analyser software. (more…)

Normally the Sonoff switches don’t support MQTT but you can buy flashed devices that run the Tasmota firmware that does.

The Sonoff-Tasmota firmware provides three interfaces: MQTT, web and serial that can be used for controlling the switch.

In this tutorial I will cover basic setup of the Sonoff Tasmota MQTT Basic Switch and how to use MQTT to control and configure the switch. (more…)

When I first starting working with computers everything was in ASCII.

However today working with networking protocols and network programming you will come across a variety of data and character encoding schemes.

In this tutorial we will look at basic encoding schemes used on computers and in the second part of the tutorial we look at how data is sent over a network. (more…)
