I have checked it and think you are right, it does look a lot as not precise like KaKu.
I have no particuler reason to ask, just curious. As RFXcom also supports it I thought I'd drop a question here to see if anyone else was familiar with the products.
I have tried a view more today and it works remakably easy to configure with homeseer, the range is also great. And even better I can get it very cheap.
If I have some more long term experience with the product I will post it here.
