Problems integrating status data of Telekom Speedport Smart 4 in Node-RED


I found a flow on GitHub to integrate status data in Node-RED (see here).

My test flow looks like this:

Unfortunately, I am unable to integrate it successfully - I always get the following error:
“TypeError: Cannot read properties of undefined (reading ‘createDecipheriv’)”

I also installed “node-red-contrib-crypto-js” as “this flow requires NodeJS Crypto module” (as the author states).

Any ideas how to fix this?

Thanks in advance and best regards,
