Z-Wave multiple controllers/z-wave js UI

Hello,

After I started with HA I found out it is a usefull program for a lot of things.

N ow I am trieing too get my z-wave stuff in it.

I do have a large number of devices (somewhat over 100). Because I read on several places that the maximum for most controllers is around 50, I do have 2 controller. A aeotec zwave stick version 5 and 1 version 7.
I want to integrate both in HA.
I don’t know in the first place if that is possible.

But I read in a topic that zwave js UI could be helfull with this.

So I am triing to install that.

But when I start up I get the next log:

s6-rc: info: service s6rc-oneshot-runner: starting

So I added /discovery but still the same error.

Can anyone help me to get this working?
