SlimmeLezer+ with Aidon 6534 (communication module 6442 S) energy meter

Bought a SlimmeLezer+ to read data from the energy meter Aidon 6534.

Installed it according to the guide. Got power from the HAN-port using the provided serial cable, but I also needed to connect it to the USB-C to get it to work well.

Once setup and connected, I used the web interface to discover that it could not parse the data from the energy meter. The following error message was displayed in the log:

Node.js with esm and app-module-path

This is a short post on how to use ESM with app-module-path in a Node.js (6+) project.

Q: Why?

Lots of benifits, easier to export/import modules.

Instead of:

console.log(...Object.entries(window.localStorage))
