Sorry to burst your bubble here, as far as ZHA 1.2 goes, they are anything but rock solid.
There's a good reason these aren't on our official supported devices list.
If they work for you, awesome.
I am not going to get into a debate on these, nor point fingers as to where the issue lies, or what specifically these are doing and or not doing that can make them challenging to keep online, the bottom line is, for new customers that are looking for stuff to just work, we won't be promoting their use in the community.
