Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Victron BLE for Node.js & Node-RED

A modern TypeScript/Node.js library to parse Victron Instant Readout BLE advertisements, inspired by the excellent keshavdv/victron-ble Python library.

What does this library do?

  • Parses Victron Energy BLE advertisements (Instant Readout) from Victron devices (SmartShunt, Smart Battery Sense, Solar Charger, etc.)
  • Decrypts and decodes the data using your device's unique encryption key
  • Works out-of-the-box as a Node.js library, a CLI tool, and a Node-RED node
  • No Python or extra dependencies required—runs natively on Node.js, including on Victron GX, Ekrano, and similar devices

Usage

1. CLI Tool

After installing dependencies and building the project, you can use the CLI to scan and read Victron BLE devices:

# Discover Victron BLE devices
npx victron-ble discover

# Read data from a device (replace ADDRESS and KEY)
npx victron-ble read <DEVICE_ADDRESS> <ENCRYPTION_KEY>

2. Node-RED Node

  • Install via the Node-RED Palette Manager (search for victron-ble)
  • Drag the Victron BLE node into your flow
  • Enter your device's BLE address and encryption key (see below)
  • The node will emit parsed data as messages

Getting Your Victron Device's Encryption Key

To decrypt BLE advertisements, you need the device's unique encryption key. You can find this in the official VictronConnect app:

  1. Pair with your device in the VictronConnect app
  2. Go to the device's Product Info section
  3. Find the Instant Readout via Bluetooth area
  4. Click Show next to Instant Readout Details to reveal the encryption key
  5. Copy the MAC address and the key

Note: The key is required for both the CLI and Node-RED node to decode data.

Why this library?

This project is inspired by keshavdv/victron-ble, but is written in TypeScript/Node.js for:

  • Native Node-RED integration (no Python or extra installation)
  • Easy deployment on Victron GX, Ekrano, and similar embedded systems
  • Modern, type-safe codebase
