The motivation of this project is to monitor and control several energy-sources like wind generators or solar panels. It will develop to a full and low-cost smarthome-solution, but for now we started to capture the weather as a basis to calculate the efficiency of the energy-sources.
The client-server architecture consists of several clients (ie. the weather-station, a station to measure the power consumption, the charge controller, rgb-controller for the lights, shutter controller, etc...
