Detect Z-Wave Controller Failure

[johnny_holden]

I want to create an event that tells me if the Z-Wave controller is not working correctly (some form of watchdog). I have Z-net. Can someone receommend how? I currently ping the z-net but this doesn't confirm the Z-Wave controller is actually fully functional.

I have an "extra" switch that I switch off then on, by a recurring event every 5 minutes. I have a second event that triggers an error message if that device ever goes "unknown" state.

That sounds sensible. You would of thought there's some kind of Z-wave controller error handling triggers available like comms error, network state, failure etc..

Have you done any kind redundancy Z-wave? i.e if the Main controller fails, can a secondary controller take over..

That would be above my pay grade; but a wonderful idea if someone can make it work.

How do you specify "unknown" in an event? The reason I ask is that i had one of lock indicate Status = Unknown, but Device value = 0 which happens to be a legitimate value and the last known state.
In other words, how does one trigger on Status instead of Device value?

[BobSpen]

I mis-stated, the actual trigger, for my Leviton switch, is a "An Error or Invalid State" which is in the drop-down for that switch. There is also an "Unknown(Value)".

If something is like "Error....Invalid" is not on the drop-down for your device, look at he device page status-value pairs(Status Graphics tab) and see if there is a value assigned to "Error,,,Invalid".

You also could try removing power from the lock, then send a command and see what value is set in the HS device.

BobSpen you read my mind. After I posted my question I was like "duh! I can reproduce node unreachable just by taking the batteries out."

Also worth noting is there are two ways a device can become “Unknown”. One is if the status goes to Unknown and the other when hs.DeviceInvalidValue = True. The latter will not show in the Status/Value of the device, only in the PED for the device. The Error/Unknown trigger is by the PED data.

Thanks Randy, always appreciate your history and knowledge of HS.
