I have been with Telldus and Vera, and now I am here. So far it works very well. It is good that the immature home automation have a vibrant community. Athom has taken some bold moves with 2.0, and I suggest that a further bold move should be taken; make the community language english only - and then make it more likely that it will exist in 2 years time - and I dont need to move on yet another time.
Right now the fragmentation into many languages is not helpful for such a small community.
