i just want to tell you about my Smartthings experience.
Ive got a v2 hub before christmas, it run flalessly for about 2 week, and i got the first problem. Some of my light switch abruptly stop working (GE switch bug, still not fix i think) -10 for smartthing
I finally fix it after some try and error.
a week later, my entire zwave network stop working for at less 3 days! and it bug again a week later! yeah! -200 for smartthings.
Even with v2 hub, LOTS of event are working on the cloud. It was, most of the time, working. But thats not why i brough a v2 hub, it was to not be a slave to the cloud… -50 for smartthing.
I had to thinker in the IDE for some of my device, not everything was working great (read lock management, rule machine) (i will not remove point there, i dont mind checking how thing work)
Thats -260 points for smartthing, and thats the end of it. This hub will be on sale soon on kijiji.
For replacement ive check OpenHAB… you realy need to do EVERITHING, still no secure class implement (lock) but you can work around that with another hub (i have an old vera2)
Event are a lot quicker to fire then anything else ive try!, everything is local. no surprise update that break your rules. The interface is not very slick, but i am sure it will get better.
If youre looking for relyability, security(you have total control), speed, then i recommand looking into openHAB. But be warn that it is something to setup properly.
ps: i am running openHAB with windows and Z-stick gen5
ps2: english is not my mother language, i did try my best to be readable.
