I can understand why users can get upset with Fibaro. I had my share of frustration with my HC2 as well. But at the end, when I look back, in past year playing with it I feel that it gave me more nice moments than bad ones. I always liked developing even I left that job for another. Making my home smarter every day gives me great satisfaction and occasional problems can't destroy that.
As far as I know there is no other Fibaro forums except French one and this international one. Fibaro UK has a link to forum, this one. I believe that forums are as good as users are, since forums are made for users to help each other and not to be official support. So, as long as there are experienced users on this forum ready to help others its goal is fulfilled.
I can check if there is some other forum for home automation, but that will be then general one where is not only Fibaro but everything else discussed. But I believe that we don't need to look around. This forum has experienced users that are always ready to help and when somebody get into difficult problems with his HC then help should be requested from both official support and this forum alike.
To be honest, this box is not TV or refrigerator, and many people will have problems with it, either because they are not willing to put some more effort to first learn things or they are expecting that merely just buying it will make their house smart. Unfortunately with Fibaro HC that is not the case, especially with HC2. This system can give a lot, but it requires also a lot from its users, especially knowledge of wireless systems, electrical stuff and at least some basic knowledge in programming rules and good habits.
So you see, this system is not for everyone, it is only for those people who like learning, or like technical stuff and have at least basic knowledge. I mean ti is much more than buying new TV and program channels on it!
HomeKit is for everyone! Simple, easy to install, easy to configure since there is no much to configure anyway Apple philosophy, strip everything away, close system as much as you can so that users just can't change anything and therefore can't *abuse* up anything That is the best choice for many people, but for geeks and people who like challenges Fibaro is the best choice that can be found on market today!
