I made a new plugin to communicate to homegear (https://www.homegear.eu) via xml-rpc, which is quite handy if the CUL stick is used to communicate with homematic or max! devices.
@sweetpi feel free to add it to the plugins page.
Currently, only the homematic thermostat devices are supported, since I only have those at hand to test. Also a lot of possible features from homegear are not exposed yet.
