Hi there,
I’m having issues with my flood sensor.
Today I had the case of a flood, but it only gave local alarm, no messages to OpenHAB.
I discovered it went offline (last updates of temperature) some days ago.
I tried to bring it near the z-wave controller and removed the battery, but the temperature still doesn’t get updated and I don’t get any messages from the node on movement.
Why is this happening?
How can I bring it back to life?
How can I monitor it’s offline-online state? (it always show online in PaperUI if the controller is online)
Thanks for your quick answer, you’re absolutely right.
I didn’t update anything before it stopped working,
using org.openhab.binding.zwave-2.5.5-20200515.172819-7.jar
on OpenHAB 2.5.4
running in docker on a QNAP TS-251D
I tried to find out something through zwave-log-viewer
but didn’t see anything strange, except missing communication from the node.
All other Z-Wave devices are still working.
These are the affected items.
Maybe it’s just lost its settings. You could try re-including it. There’s a bit more to that than removing the battery.
Detecting a failed battery zwave device is a challenge. Most of the time, it’s asleep and indistinguishable from broken or missing.
If you have an Item that gets updated periodically (like your battery), you can detect when one or more updates gets missed. The expire binding is useful for that kind of thing.
