The project is an thermostat(CV) interface which is suitable for the older CV on/off systems and Opentherm as well. The system consists of an Gateway that enables communication over the web. Depending on your preferable solution the Gateway can be accessed via an port-forwarding setting on your router or the Gateway contacts an server thus avoiding difficult router setting.
