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 🙏

Readme

node-red-contrib-powermateble

A Node-RED node for interacting with a PowerMate Bluetooth device.

Under the hood, this node makes use of and thus has a dependency on the noble Node.js library.

Prerequisites

Linux

  • Node.js v0.12.x or greater
  • Bluetooth

Install the prerequisite bluetooth libraries by running the following command.

sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev

Optional: The noble library requires Node.js to run as sudo or root. Run the following command to grant the node binary cap_net_raw privileges so that this is no longer a requirement.

sudo apt-get install libcap2-bin
sudo setcap cap_net_raw+eip $(eval readlink -f '/path/to/node/binary')

Install

Run the following command in the root directory of your Node-RED install

npm install node-red-contrib-powermateble

Usage

powermate-in

A node that listens to a PowerMate Bluetooth device for device events.

Select or connect to a new PowerMate device via the Device field by entering it's MAC address. The msg.payload property contains the parsed event value. Additionally, msg.topic contains the name of the captured event.

Possible events/value combinations are:

powermate-led

A node that sets the brightness of a PowerMate Bluetooth device LED.

Select or connect to a new PowerMate device via the Device field by entering it's MAC address. Enter the percentage brightness into the Brightness field to set the devices LED brightness. If left blank the passed in msg.payload will be used.

Setting a value of -1 will pulse the LED.
