Z-NET – Unknown State

Hello –

I have a Z-Net (Version 1). On 9/24/2016 my Z-NET status changed to “Unknown”. As far as I can tell my Z-NET is functioning fine. I am able to connect and disconnect without any issues and I can communicate with all my Z-Wave devices. Any idea what would cause the Z-NET to display an “Unknown” state – and should it be a concern?

Thanks
Mike
