Cool thanks, have managed to fix mine by removing the device from the alarm, rebooting the alarm and then re-adding it. Now the battery status correctly reflects new batteries, fingers crossed it updates over time and that it doesnt kill the batteries (which when I last tried using ST Hub and the old Z Wave module, I found batteries lasted 4 weeks at best!)...
Its been 8 month since the alarm was released in the UK - has anyone found a 3rd party z-wave siren that works properly with the Ring Alarm ?
I've seen some that can be added but only appear as a manual on-off like a light switch in the Ring Alarm - it could not be associated with the alarm state (e.g. go off when the main alarm goes off).
For battery life I got about 6 months with the batteries provided. Replaced with Duracell Plus, so that should last longer. Unfortunately, I ran into the same problem of Ring indicating the batteries are dead after replacement, so I removed and added the lock back to Ring. It works correctly now, but it looks like this is a limitation (problem) with the integration, and that it will have to done for every battery replacement. So maybe this is something to fix before we can have it as a official 'Works with Ring' device?
