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.

envirophat-mqtt

Publish sensor updates from Enviro pHat to MQTT

Calibrates the temperature reading for variance caused by heat from the CPU of the Raspberry Pi and smooths the data using a moving average.

A factor of 1.2 works well for me, but may vary depending on case and environment.

Running

sudo npm i -g envirophat-mqtt
envirophat-mqtt

Use PM2 or similar to run on startup.

Configuration

Create a config file at /etc/envirophatmqtt/config.yml

Check the available settings and defaults in config/defaults.yml.

Example:

---

mqtt:
  host: '192.168.0.123'
  topic: sensor/loune/input
temperature:
  factor: 1.2
interval:
  duration: 60000

Pre-requisites

Pimoroni libs: curl https://get.pimoroni.com/envirophat | bash
Node js

Why Node js?

Selfish reason: Because all my existing home automation runs on Node js managed with PM2.

Even though the provided libraries are Python, and it's pretty easy to publish to MQTT from Python, I wrote this so I could run my entire platform on Node js.
