I was an early adapter with my zipatobox (nr 1) at that moment they had version 0.05. slowly on more and more functions where developend but at a certain momemt they moved from version 0.9 to 0.99 to version 0.999 etcetera.

now about 5 years later they still have several bugs. For that reason i am migrating to Homey. I have more than 50 zigbee and Z-Wave devices in house.
