Log entries look something like this. At 2:08:09 I unplugged and then plugged in a Z-Wave relay switch. Indigo immediately received the status message from the module.

Z-Wave received "Office Fan Switch" status update is on
Then 20 seconds later I executed an action that is supposed to turn it off and on. Indigo wasn't able to communicate with the module.

This is happening with all of my Z-Wave devices. Is this a symptom of some well-known scenario? It has been working just fine for a couple of years now, and I'm baffled.
