Just got the new C8, easy migration from C7.
138 devices.
Old user (literally 62, so be nice smart young people) but avid home automation enthusiast going on 7 years. Started with the "gateway drug"; wifi - soon, adios. Then went Wink, you how that went. Went SM and about 4 years back bought my first C5 and never looked back. Just made the migration
from C7 to C8, 20 minutes tops. Not a speed bump. The VERY first attempt and for the very first time in 7 years - zwave repair ran fast and all 138 devices checked in fine - zero errors.
This was on the C8, first try. You guys are an amazing company and make life better - thank you. jj
