Hi there,
I am currently busy designing a MySensors API. This project is named OhMySensors and is available at https://github.com/marvinroger/OhMySensors. Don't mind the front-end code yet.
This is basically a node.js application acting as a controller, and as a storage layer for the data sent by the sensors. All the data is available through a WebSocket API, documented on the Wiki.
Do you think the API is well designed? Would you change something? If there are some front-end devs around here, would it be easy for you to build a front-end based on this API?
Thanks for your feedbacks.
