I am running Redmatic on my CCU3 without trouble. Now i would like to have a testbed seperate from "production" if you like. I did setup another instance of Nodered on a seperate (x86!) Server and left redmatic on the CCU (arm).
I did install almost all plugins fine, but node-red-contrib-ccu seems to make trouble. After i imported all flows from my CCU into the non-prod Node Red i get a warning that flows are stopped by a missing Nodetype: ccu-connection
I also habe no way of configuring an external one as the edit button is missing:
I understand that there are obvious CPU Architecture differences but i was still hoping to be able to use Node-Red with an "non-localhost" CCU - my mistake? I can have a look running a VM of Redmatic (available for x86) somewhere but i hope i can simple skip to maintain another OS instance... Any ideas?

Go into your `.node-red` folder and run
`npm remove node-red-contrib-ccu`
`npm install node-red-contrib-ccu`
and if the install does not end with something like
```auto
+ node-red-contrib-ccu@3.4.0
added 39 packages from 62 contributors in 10.389s
```
then copy/paste the output from the install command here. Use the `` button at the top of the forum entry window when you paste it.
If it does end as I showed then restart node-red and see if it is now ok.

well, i still have no possibility to add a CCU:

Yes the first line tells you it wants nodejs version 10 or better and you have node 8.

agree - installed nodejs 10 and it seems to run now but looks like there is still a [problem](https://discourse.nodered.org/t/redmatic-and-external-node-red-show-different-behaviour/37917/2) that the datapoints don´t go through...
