I use DietPi as OS on my RPi's. When installing latest versions I found out it installs Node v14.xxx, which causes problems when installing wmbus-client node. Let's say node-red is allready installed. This node uses Serialport v6.2.2 which can not be installed in Node v14.xxx and v12.xxx So node should be downgraded to v10.22.0. How to do this: Check what node version is installed with node-red: node -v If version is higher than v10, then follow below: Remove serialport if exists: npm remove serialport First install "n" package with npm like this: npm install –g n Downgrade "node" to version 10.22 (and npe v6.14.6) like this: sudo n 10.22.0 Check node version with command: node -v restart RPi: restart When rebooted, open web page of node-red, go to manage pallete and install "node-red-contrib-wmbus-client" Now you should see nodes present in node-red, and you can also select com port (USB) in config.

This should now be fixed (better late than never)
