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-sm-bas

This is the node-red node to control Sequent Microsystems Building Automation Stackable Card for Raspberry Pi.

Manual Install

Clone or update the repository, follow the instrutions fron the first page.

In your node-red user directory, tipicaly ~/.node-red,

~$ cd ~/.node-red

Run the fallowing command:

~/.node-red$ npm install ~/megabas-rpi/node-red-contrib-sm-bas

In order to see the node in the palette and use-it you need to restart node-red. If you run node-red as a service:

~$ node-red-stop
~$ node-red-start

Usage

After install and restart the node-red you will see on the node palete, under Sequent Microsystems category 7 new nodes:

BAS triac

This node will turn on or off a triac. The card stack level and triac number can be set in the dialog screen or dynamicaly through msg.stack and msg.triac. The output of the triac can be set dynamically as a boolean using msg.payload.

BAS 0 10V in

This node reads one 0-10V input channel (Make sure the corresponding jumper is in the "0-10V" position in order for this read to be correct). The card stack level and channel number can be set in the node dialog box or dynamically through msg.stack and msg.channel. The read is triggered by the message input and output can be found in the output message payload as a number representing the voltage readings in volts.

BAS 0 10V out

This node controls one 0-10V output channel. The card stack level and channel number can be set in the node dialog box or dynamically through msg.stack and msg.channel. The value in volts is set dynamically as a number between 0..10 thru msg.payload.

BAS R 1K in

This node reads the 1K ohms thermistor input channel(Make sure the corresponding jumper is in the "1K" position in order for this read to be correct). The card stack level and channel number can be set in the node dialog box or dynamically through msg.stack and msg.channel. The read is triggered by the message input and output can be found in the output message payload as a number representing the resistance readings in kiloohms.

BAS R 10K in

This node reads the 10K ohms thermistor input channel(Make sure the corresponding jumper is in the "10K" position in order for this read to be correct). The card stack level and channel number can be set in the node dialog box or dynamically through msg.stack and msg.channel. The read is triggered by the message input and output can be found in the output message payload as a number representing the resistance readings in kiloohms.

BAS DC cnt

This node reads the dry contact input cunter for one particular channel and set the counting edges for that channel. The card stack level and dry contact inplut counter channel number can be set in the node dialog box or dynamically through msg.stack and msg.channel. The rising edge counting and/or falling edge counting can be enabled/diabled with coresponding check box in the node dialog. The edge settings are sent to the card every time you deply nthis node or the flow start or you select different channel for read through msg.channel. The read is triggered by the message input and output can be found in the output message payload.

BAS DC in

This node reads the dry contact input state for one particular channel(Make sure the corresponding jumper is in the "1K" position in order for this read to be correct). The card stack level and dry contact inplut channel number can be set in the node dialog box or dynamically through msg.stack and msg.channel. The read is triggered by the message input and output can be found in the output message payload as boolean.

Important note

This node is using the I2C-bus package from @fivdi, you can visit his work on github here. The inspiration for this node came from @nielsnl68 work with node-red-contrib-i2c.Thank both for the great job.
