I've been happy with 2.2.4- no noticeable issues with my z-wave mesh, all devices and rules behaving normally, with one exception. My ZSE19 multisiren hasn't been nearly as reliable since 2.2.4.145.
I have a smattering of Ecolink contact sensors on exterior doors, and one Sensitive Strips Guard on the front door. I have a very simple rule that instructs the ZSE19 to play a sound from its library whenever one of these sensors shows open. This worked flawlessly in 2.2.3, however I've noticed problems since 2.2.4.145. I wasn't paying attention before .145, but the problem may have been present in all 2.2.4 builds.
The contact sensors all work well- open/close events show up in the log immediately. Also logged are the commands sent to the ZSE19- it shows that it's being instructed to play chime number 38 every time. However, I often don't hear a chime at all. Sometimes it's delayed by many seconds, and sometimes it plays the chime 2 or 3 times, despite only being told to play a single chime. The ZSE19 is paired S2 Authenticated, and has been since 2.2.3...
Any ideas?
