Basically ok. is the installation and commissioning, if the software has only once made the network connection to the Cube, is the application and the structure of the components very well.
Super also the window contact history, these works quickly and reliably.
If the system would work consistently clean, it would be a dream. Using timing daytime when unused, cool and at the right time at the right temperature brought spaces.
Prima example is the Bad: When the morning the first goes to the bathroom, does not have to turn up the heating and maintenance. It is already cuddly warm. And "turning heating down" the annoying or same forgetting there is no longer even that concerned the timing. Theoretically.
But: Unfortunately, the system is far from functioning throughout. I'm really sorry it now, constantly coming up error messages like "the server is not available", etc. In most cases, of course, when you're not at home and just using iPhone or VPN (VPN yes, is a web interface for the Cube for PC or MAC it does not want) to access the controller.
Time you get a message that certain parts are not accessible (usually the wall switch next to the door), sometimes the condition is it not displayed window contacts correctly (although the HT`s do everything right). Most recently: All thermostats appear when remote access to target temperature 21 ° C, although the timing is active and actually completely different temperatures should be in the house.
In addition, for me is not clear why only times nothing happens when the temperature is controlled manually at HT, it goes by at least 1 minute bit of HT (audible) governs.
And the biggest mischief for me is that the HT`s all illuminated displays, the room thermostats are not. Just hang this but often in darker corners of the room!
All in all, the system is simply not round and not thought through. Disturbing is especially the unreliability and this will probably be the deciding factor, time to try something else.
