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 heatweb Thermal Integration heat heat networks

node-red-contrib-heatweb

A Node-RED set of nodes for interacting with Heatweb systems, handling message topics, and data storage.

Pre-requisites

There are no pre-requisites.

Install

Run the following command in the root directory of your Node-RED install. This is usually ~/.node-red

    npm install node-red-contrib-heatweb

Usage

Heatweb Connect Node

A single connect node should be used for establishing a link to the Heatweb server, and for initialising global variables.

Global Variables

readings - A nested object containing all message data.
node - A unique alpha-numeric identifier for the instance.
networkId - A unique alpha-numeric external identifier for the network.
localNetworkId - An alpha-numeric internal identifier for the network.
topics - A nested object containing the dictionary for interpreting messages.

Message Handling Node

Messages (data) fed into a handling node are stored in memory under the global readings object, and appended with additional relevant data extracted from the global topics object, such as a description and units of measurement.

Message topics are conditioned to match the standard 5 level Heatweb MQTT protocol:

network / publisher / device / data type / data key
