Have the system now for about a week in use (Cube - 8 radiator thermostats - 1 Wandtermostat and 1 Eco switch Unfortunately a total flop. The system runs on the latest software (1.4.2) extremely buggy and hangs regularly in use on. The decor is simple and fast (this had already been forcibly x-times tested), but after that the trouble starts. The Cube is simply no longer accessible, although you can ping it and the LEDs "Power" and "Internet". When starting the software (on Windows 7), the Max! Cube quickly found, it is then retrieved in seconds the software version and then the browser attempts (whether Chrome, Firefox or MS Internet Explorer) to connect to the cube. PC and Cube depend on the same switch and the same IP network, yet the browser hangs when loading. No logs and no useful error messages. If I reset complete the cube, I can connect me immediately and configure the devices. Not later than the second or third attempt to connect me again, this is no longer. On the manufacturing side, there is no support or assistance. In a word: Stay away! The stuff is extremely immature and not running!
