Constantly total failure of the system

Since the portal through which the control via Internet or smartphone app is possible, constantly is offline because the operator is not on the series get to keep it going, the whole system is completely useless and a waste of money. Too bad the potential to be a great product, the system has. If not for the following would be (an excerpt):

Configuration is hakelig.
App is in your functions trimmed (no programming of temperature curves possible only simple +/- function and mode change)
Portal umpteen times been offline since the purchase about 2 months ago, at least 5 outages that have stopped in some cases for several days, but at least several hours. Every failure means that neither my app still at home via computer, the heating can be controlled. Per computer at home (and only on the computer that is connected to the same router as the Cube), it's all on the allocation of a fixed IP for the Cube, which represents a major obstacle for laymen. In addition, one may then every time you leave the house, the Configuration switch again because perhaps at some point again the portal is erreichhbar and you want to control the heating via app or from the Internet. That's the whole point of the system (!).
-Serverumzug Was made, since it does not work better, but even worse, even more failures.
-Diverse Bugs (eg window contacts must be re-learned, one is with the window open the mode for the room changes once v)
-support Does not exist in principle. Either react the support until at least one week after the request (which is only possible by e-mail ...), or he does not react. When a response comes, a abwiegelnde Standard Mail.

All in all, just awful and a disgrace, I am very disappointed and can only strongly advise against any of the purchase. Anyone who wants to can gain an additional impression of the "reliability" of the system here by times "unreachable max portal" google for and the thread in the forum by ELV reads. 116 posts which give a good picture of what you intend to buy here.

I can see the dealers selling the product, only advise to put pressure on the manufacturer to ensure that the constant problems come to an end. Then could be a really good thing.
