Hi!

I have a HomeMatic IP system - RaspberryMatic with RedMatic addon (it has Node.js 14) - which works without problems with node-red-contrib-ccu to control everything.

I want to move to a separate pi that I installed with the command from [Running on Raspberry Pi : Node-RED](https://nodered.org/docs/getting-started/raspberrypi) and it installes a Node.js version of 12. Unfortunately, with the same version of node-red-contrib-ccu, it is not possible to control the HomeMatic system. Is there a possibility to update my Node.js version to 14? Just for testing, it is not a productive system.

v14 is an LTS version and is supported by Node-RED. You just need to update node.js however, you should then do:

```auto
cd ~/.node-red
npm rebuild

```

to make sure that all of the compiled libraries are correct.

Thank you!

But how should I do it? On the command line with some command? Or adding some repository to the sources.list and use apt-get?

Edit: Ah, found the repo file!

Edit 2: Update was successful, but doesn't solve the problem 😟

Did you re-install node-red and run `npm rebuild` in the .node-red folder after upgrading nodejs?

Double-check that Node-RED is using the correct version. It is shown at the start of the log.

No, only rebuild, but not re-install. Is that necessary?

Yes, it is necessary to re-install node-red, or at least it is desirable, so that anything in node-red that has to be built is rebuilt using the new version. You can do that with  
`sudo npm install -g --unsafe-perm node-red`

Then restart node-red.

Okay, I didn't know that, though it doesn't solve the problem. But I learned something new 😃
