Z-Stick and RPi4 Programs

Evening All,

I am having a bit of difficulty with my ZWave network and was hoping for some advice. I am using the Aeotec Z-Stick Gen5 with a RPi4 installed with Raspbian then HASSIO on top. I am aware of the bug with the ZStick and the Pi4 and I have it plugged into a USB2 hub and I experienced an intermittent issue twice where I rebooted the Pi and HASS just could not operate the stick but a few reboots and it kicked in and once running it was perfect however I have done a config change tonight rebooted and I cannot get the stick to work at all! This time it is saying the Network is started in HASS and all the nodes are shown but they all say Undefined and from the Lovelace UI all the cards say Unavailalbe.

Looking at z-wave logs it all seems to startup find then each node looks like this:

2020-01-18 22:03:24.148 Info, Node002, Sending (NoOp) message (Callback ID=0x0a, Expected Reply=0x13) - NoOperation_Set (Node=2): 0x01, 0x09, 0x00, 0x13, 0x02, 0x02, 0x00, 0x00, 0x25, 0x0a, 0xca

Later on I get messages like this:

2020-01-18 22:16:31.133 Error, Node005, ERROR: ZW_SEND_DATA could not be delivered to Z-Wave stack

Does anyone have an ideas or suggestions pretty please?

Ok after giving up last night I have managed to get it working this morning by unplugging the USB hub, rebooting the Pi allowing it to be fully booted with HASSIO then plugging the hub in leaving it for a few minutes then initiating a reboot of HASS and its all happy again.
