Experimental OpenHab Cloud Server goes online

by thorsten 0 Comments

After lacking the bandwidth to finalize my original idea of an AMQP based IoT backend, I started to shift my attention to OpenHAB. It’s an open source project which provides much of what I originally intended, with a different implementation, but much more flexibility in terms of bindings etc.

One of the major differences of course remains that VeliSphere was intended to address broader IoT use cases, whereas OpenHab is really focused on the Home Automation use case. As I am currently planning to install Z-Wave in our soon-to-be-built house, it comes in quite handy.

I will try to preserve the Velisphere Designer, which I found quite decent in terms of functionality, and make it available as graphical “rules designer” for OpenHab.

In the meantime, I’ve set up my own OpenHab cloud server for testing. It can be found here: https://openhab.connectedthingslab.com

This is, for the time being, just the plain “openhab-cloud” reference server as found on the project’s GitHub repository.

Notebook monitoring tutorial app in action, with dashboard shown

In this tutorial, we will build a little application to monitor some parameters of a Linux Notebook (CPU core temperature, HDD SMART health status, battery charge level for batteries #1 and #2) and control certain actions on your notebook (sleep mode, reboot, shutdown).

The entire code for this tutorial can be found on https://github.com/thomeudt/VelisphereClientSDK/tree/master/DemoNotebookBatterySensor

Why try Velisphere

Why try Velisphere

Velisphere provides a middleware layer as well as a web based, „responsive design“ user interface for data communication within and management of the internet of things.

When we started to work on Velisphere, we concluded that the internet of things is limited by the general lack of standardization, which subsequently led to a closed „device-app-ecosystem“ that causes the need for the user to use a different app for each internet connected device and a lack of direct interaction between devices or services of different categories from different vendors.

Everything wired up

In this tutorial, we will turn a RaspberryPI into a multi-sensor device that connects to Velisphere allowing to track and analyze sensor data. In a later tutorial, we will expand on this setup by adding a relay than can be controlled via Velisphere rules. But let’s concentrate on building the sensor device first.

Get in touch

We are still a couple of weeks away from launching our beta phase. However, I’d like to invite you to get in touch with us to learn more about our project and to explore ways of leveraging our upcoming ecosystem for you Internet of Things (IoT) project.
