Long story short, I have a zwave deadbolt that will suddenly go offline without warning. It will take days/weeks/months to realize it is no longer powered. I have tried setting up a battery alert when the power level gets below a certain percentage, but the power drops from, say, full charge to dead with no warning. I need another way to trigger that the lock is dead.
Is there a way to trigger a rule based on when the last time the deadbolt was updated, natively? I know I could set up a variable that updated every time the lock was locked/unlocked, but if something was already there that would make things easier. For example, something that looks at "Last Activity at" under the device details. I looked under Custom Attributes for that device and there is nothing that would work.
Thanks for the reply. Yes, I think I know the trouble. One of the terminals in the battery compartment is slightly corroded. I only use NiMH batteries, so I'm not sure how the corrosion keeps occurring, but I clean them off with distilled vinegar and it starts working again, until it doesn't. And when I say it is slightly corroded, I mean slightly. Nothing caked up, just barely discolored. I'm going to see if I can find a replacement battery compartment, but other than that or until then, I am trying to bandaid the issue.
