This document discusses interoperability issues with connecting devices in the Internet of Things. It provides examples of devices like a washing machine, solar panel, car, and smart grid operator that need to communicate but face problems due to different data formats and APIs. Potential solutions discussed include manual integration, common standards, and universal APIs, but so far none have fully solved the challenge of enabling seamless communication between all connected things. The document promotes the company CloudRail and its approach using a cloud-based definition server to automatically convert between data formats and serve as a universal API for Internet of Things devices and applications.

5. Smart Home / Grid Example
1. Washing Machine > Solar Panel: Enough energy?
2. Solar Panel > Washing Machine: No!
3. Washing Machine > Grid Operator: Cheap energy?
4. Grid Operator > Washing Machine: No!
5. Washing Machine > Car: Surplus energy?
6. Car > Google Calendar: Appointments requiring the car?
7. Google Calendar > Car: No!
8. Car > Washing Machine: Enough energy for washing!

8. Situation today
Light on
Heating off

9. Problem
Different APIs, Data Formats, Semantics
Communication often impossible
X X

10. Solution Approaches
Manual Integration
N:M Problem, Maintenance, Lack of Reusability

11. Solution Approaches
Common Standard
E.g. AllSeen Alliance, Apple, Google
Takes long to agree on, imposes limitations

12. Solution Approaches
Universal API
e.g. IFTTT, OpenHAB, CloudRail
None is really universal as of now
