Home Networking, MQTT and Home IOT

Hi and Welcome to Steve’s Internet Guide.
beginners guide internet-and-networkingIn 2017 over 3 billion people where connected to the Internet (Wiki), and over the past 10 years the Internet has become just as important as TV, radio, and the telephone.

The use of the Internet,networks and related technologies is growing.

The Home Network

Today’s home and office networks are built around the same protocols and technologies as the Internet. See TCP/IP protocol suite explained

The home network or home office network will form the hub for your internet connection allowing all devices, play stations, tablets, computers etc to connect together and to share an Internet connection.

With the growing use of Internet and network enabled devices there will a growing need for almost everyone to have a basic understanding of networking so that they can setup, configure, and use them. See Setting Up a Home Network

The Home Internet of Things (IOT)

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).

Every object, both real and virtual, connected to, and accessible over the Internet is the basic idea of the Internet of Things or the internet of Everything.

The home IOT will probably use the same technologies as the industrial IOT and I hope to cover them as they develop. See- Beginners Guide to IOT

MQTT (MQ Telemetry and Transport)

MQTT  is a M2M (machine to machine messaging protocol) and is emerging as the main messaging protocol for IOT and Home IOT.

Python and JavaScript Programming

Being able to Program is becoming a basic requirement for anyone in computer networking.

The site will concentrate on Python but will also contain many JavaScript examples focused on node-red.

If you have any questions please ask

Best Regards Steve

Logging MQTT Sensor Data

Data from sensors will need to be stored. But how much do you really need to store?

Many sensors like state sensors (ON/OFF), temperature etc will fluctuate very little over the course of a day so does it makes sense to store the same sensor value every x seconds? (more…)
