IoT and the Smart Grids

In this blog I will discuss IoT and then Smart Grid revolution that is changing the way electricity is going to be supplied over the next few years. Why is this important? – To build connected devices and services that help businesses and homes drive a greener IT agenda, you need to understand the road ahead so you can benefit from the changes coming.

Introduction – IoT, the cloud and connected devices

The Internet of things (IoT) is changing the way devices are connected and used. Building on the top of modern cloud infrastructures such as Amazon, Docker etc it has become easier than ever to roll out, scale up and scale down your own connected services.

Embarcadero recently ran the 4 day IoT boot camp showing how to use the powerful RAD Server middle tier technology to automatically manage a network of connected devices made with Arduino that can be connected to via any modern programming language using REST.

Seeing emerging technologies for managing a wide network of devices certainly got a lot of developers egger to build their own connected solutions. But devices will need to connect to their local environment too to get the best value out of the Internet of things.

Protocols such as Zigbee and ZWave are at the heart of the future of the connected home. These protocols are easy accessed when building RAD Server Thing Points via the 50+ IoT components in RAD Studio. Click for more on Delphi and C++Builder and the Internet of Things.

How is IoT and the Smart Grid related?

Zigbee and ZWave are important protocols for the connected home. The future smart hubs in homes that will be connected to the electric meters will enable local devices to discover when is most cost effective to use electricity, e.g. enabling you to charge your Tesla car, or Power wall during time where electricity is in abundance and offered dynamically at a lower cost rate. Being able to judge demand and share and spread electricity usage to increase capacity is one way connected devices in IoT will interact with the Smart Grid via smart hubs.

I recently did a Roadmap for Smart Grids and last Friday I spent some time with Jim McKeeth and Nick Hodges talking about Smart Grids as a guest on their weekly Delphi.org pod cast.

New Eddystone beacon format from Google

Google Eddystone™ beacon format

Give your users better location and proximity experiences by providing a strong context signal for their devices in the form of Bluetooth low energy (BLE) beacons with Eddystone™, the open beacon format from Google.

I found out today about a new Bluetooth LE beacon format that google have released called Eddystone.

This makes 3 formats for beacons along side AltBeacons and iBeacons.

The Eddystone format, like AltBeacons, is an open beacon format but allows the inclusion of additional data blobs with the beacon that can be updated once the beacons are deployed. A key part of this vision from Google is an integrated cloud based API’s that Google may well hope puts them at the centre of the growing beacon ecosystem.

Using Azure Translator Services with Delphi

Often when building IoT applications there is benefit in linking to 3rd party services. e.g. Heating control systems may link to weather services to help detect external influences that may effect their operation. Typically these services are exposed via JSON and REST providing multi-platform access.

Microsoft Azure data services offer access to a wide range of datasets and services and in this blog post I will take you over my journey connecting to the Azure translator data service and achieving translation of text on Windows, Mac OS X, iOS and Android thanks to the REST components and helper classes in RAD Studio XE8.

About Microsoft Azure Translator Data

Microsoft Translator is a WEB API that enables Automatic Translation (Machine Translation) of text between any of the 50 supported languages

The Azure Translator data is used by Microsoft Office, Visual Studio, Bing and many more Microsoft products. It works over REST using a mix of JSON and XML to provide a number of services including translation and text to audio.
