I've recently been looking at different ways of using my Omega and Pi's.
I've come across Cayenne which uses an agent on a Pi to control it, similar to Onion Cloud without as much granularity.
Also Initial State which looks pretty cool, its a way of recording data from sensors primarily but you can store other datapoints too. So a temp sensor or humidiy sensor, you can stream values to a REST API. Looks promising although there is a free and paid model, the free level could be limiting.
