Z-Wave ZME_UZB1 "hangs"

[hyla]

Hi,

I'm using a Z-Wave ZME_UZB1 Me USB Stick and a Fibaro wall switch.
Every now and then I lose connection to the ZWave devices and have to reset my RaspberryPi.
The USB stick is powered via a USB hub. Domoticz version is 3.5176.

Is there a solution to this? Like a cyclic reboot of the Z-Wave device? Or a check if it is reachable
and a reboot if it isn't? How would I do that on the Raspi?

Thanks,
Christoph

Do you use a separate power supply for the USB hub?
Could be that your raspberry hasn't got enough power for the UZB1

Yep, two separate power supplies ...

Could it be something that it is not same ground? since you have a different power supply for ZME?

Is it possible to upgrade firmware for ZME_UZB1?

Try if is works better when you connect it directly to you pi.

Some USB sticks don't work well when they are connected by a hub of even an USB extension cable.
