relayr's ‘WunderBar’ Internet of Things starter kit to be distributed by Conrad

June 25, 2014 // By Graham Prophet
Distributor Conrad Business Supplies has announced that it is working exclusively with Berlin based start-up company relayr (iThings4U GmbH) to support the development and launch of the Open Source ‘Internet of Things’ (IoT) starter kit known as ‘WunderBar’.

relayr is a start-up that is focussed on enabling applications using connected devices, and providing the infrastructure that will allows many of the product concepts currently circulating as Internet-of-Things ideas, the get the real world and to function. Medium- and long-term, relayr's business model is to, in effect, 'commoditise' aspects such as the cloud services that will produce real and useful services from the IoT. The company is considering models similar to the “app” environment with revenue streams coming from small subscriptions or one-time payments, for IoT-based functions and services. It is developing a range of offerings such as its Open Sensor Cloud concept, which will be an environment where data from myriad smart devices can be collated and made useful by an embedded rules engine.

More immediately, relayr believes that there are many would-be IoT “application” developers for whom, “hardware is hard” - for this group, who don't have a problem in coding functions, the practicalities of actually getting sensor measurements connected to a context where they can do “connected-device” operations, is a barrier. Therefore, the company has designed WunderBar.

In March this year, the WunderBar project successfully completed its crowdfunding campaign on the hardware crowd funding platform Dragon Innovations, where it achieved 120% funding.

The WunderBar IoT starter kit together with the relayr Open Sensor Cloud platform allows software application developers to quickly and easily begin working on wireless applications and prototype building based on data gathered from the physical world without needing to learn about hardware. The platform includes software development kits (SDKs) for iOS, Android and Node.js.

The “-Bar” part of the name allude to a chocolate bar, in that the product comes as a single PCB that can be snapped into functional “bites”. There's a host module with a Freescale ARM Cortex-M MCU (“deliberately overkill” in terms of its performance, relayr says, leaving headroom for application code) and a Gainspan WiFi module; the host and
