I won't say that eedomus box is slow. But it is junt not fast enough.
Especially what relates to rule engine. When I use eedomus rules to automate light on motion - it works but sometimes with several seconds delay between motion and action. That is why I have to use direct association between ZWave devices - works much better.
With aeon keyfob it also works fine almost all the time, but sometimes takes up to 10-15 seconds to react on button press. In comparison - rules on Fibaro HC2 work almost immediately most of the time.
I guess the main factor is actually perfomance in eedomus. Is there any plans to release a faster eedomus box version?
Vera plans to release a Pro version with a new user-friendly UI and better perfomance (1 Ghz, 1 Gb), and then I believe it become a serious competitor to eedomus. http://blog.domadoo.fr/2013/01/09/micas ... les-veras/
