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.

node-red-contrib-battery

A Node Red node to get information about the battery

Install

Run the following npm command in your Node-RED user directory (typically ~/.node-red):

npm install node-red-contrib-battery

Node Usage

Get information about the battery by injecting a random message into this node:

Flow

The msg.payload of the output message contains a lot of data about the battery:

hasbattery: indicates presence of battery.
cyclecount: numbers of recharges.
ischarging: indicates if battery is charging.
maxcapacity: max capacity of battery.
currentcapacity: current capacity of battery.
percent: charging level in percent.
timeremaining: minutes left (if discharging).
acconnected: AC connected.
type: battery type.
model: model.
manufacturer: manufacturer.
serial: battery serial.

Limitation

This node can be run on a number of operating systems, but check this table to make sure the required information is accessible on your platform!

Most systems running Node-RED wil not contain a battery. For example on Raspberry Pi, the msg.payload.hasbattery field will contain false and all other fields will contain no data ...
