It seems that something has changed in the Z-Wave binding since at least 2.5.0.M3. I noticed that in 2.5.0.M3 devices would randomly go offline without explanation, and would only come back after I manually performed a network sync. Every most devices would go offline, and when I’d wake up in the morning my z-wave light bulbs will be turned on, and openhab would say they’re offline. So I rolled back to 2.5.0.M1, and have had no issue for weeks. Yesterday, I saw that 2.5.0.M4 had been released, so I updated my system to see if this issue has been fixed. It has not. I noticed after a few hours, one (little used) device went offline but I figured it was an isolated instance because everything else appeared to be working. This morning I woke up to find my bulbs turned on, and offline like before. I check openHAB, and a bunch of my devices are marked offline again. Now, I’ve tried to search for this issue before and I couldn’t quite find something similar… I would like to try to resolve this issue, rather than forever being stuck at 2.5.0.M1, so if any one has any idea what could be going on, I’d love some input.
