kandi X-RAY | home-automation Summary
There's a lot of consumer automation packages available, as well as a lot of home-brew projects (Arduino, ESP8266). I personally found many of them quite limited in scope and flexibility, and more importantly, reliability. There are many advantages of a PLC-centered design: device control and automation is not reliant on any computer systems, external software, services, or consumer grade hardware. The hardware you do get has orders of magnitude more I/O protection and reliability over something like an off the shelf consumer automation system, coupled with a robust RTOS running your logic. These devices are designed for long term use in harsh industrial environments - in a typical home environment they should last forever with no user intervention.

QUESTION
I have a few web-based local application for home-automation purposes, those are accessible through IP addresses something like http://192.168.1.100:8080 but what I am trying to achieve is to link each individual IP to a internal domain, so that anyone can just enter http://kitchen.home to access that server without messing around with their hosts file, at the same time http://192.168.1.100:8081 should be served as something like http://hall.home.
...ANSWER
Answered 2017-Aug-30 at 19:00DNS names are independent of port numbers. A dns record correlates a name to an IP address. If you want to omit the port number from urls, you either need to host on the default ports (80/443), or use a proxy.
With a home network, the dns can be tricky, and usually depends greatly on the specific router you have. Your options are basically:
- Maybe your router has an interface for defining host overrides. OpenWRT has such a thing, and some routers have a similar dns server on them that you can add host entries to.
- Get a public domain name. You can have an
Arecord forexample.comthat points at a local network address. The server itself may only be accessible inside your network, but the dns will be available anywhere. - Run your own dns server and tell your router to use it as the default resolver for your network.
- Maybe mDNS could suit your needs for .local domains.
QUESTION
I have the experience with ReactJS and I have built the web app with react. But I have seen the home automation from deepsyx https://github.com/deepsyx/home-automation
I have tried to run server in "server" directory but it's error
...ANSWER
Answered 2019-Apr-20 at 15:38I've got it to run React Home Automation Server. I hope this could help all newbie like me to do the home automation on Raspberry Pi.
I found 2 steps:
I found the problem that it cannot find "home-config" directory so I go to "home-config" directory and copy "index.example.js" to "index.js".
In the virtualbox need to add "../" to
const homeConfig = require('../home-config');fromconst homeConfig = require('home-config');but cannot run anyway because of not raspberry pi environment.I get the error from running temperature sensor "DS18B20", then I fix
const deviceFolder = files.find(file => /^10/.test(file));toconst deviceFolder = files.find(file => /^28/.test(file));in "server/utils/temperature.js" because my raspberry pi 3 generate "28-01131faf1feb directory.
QUESTION
This is for a Microsoft tutorial that I am attempting to modify, running in a Jupyter notebook. The example code imports a .wav file and plays it.
If I change the URL in that code to import a different .wav file, it should import and play that .wav file instead. However, the notebook will not import the new wav and will not play it.
The two .wav files have the same sample rate, so it's not that. I have tried doing this with Dropbox and Google Drive links as well, no luck. I even tried downloading the example .wav file, uploading to my own GitHub, and then curling it into the script, and it still did not work.
This code (from the example) works just fine:

Answered 2019-Feb-14 at 12:46Obviously there's an issue with the file you're receiving. curl's output says it's just 15 bytes, too small to be a playable audio file.

QUESTION
I have a question regarding node-red, before jumping on it. I find a big difficultly to get a home-automation tool such as node-red, to get working multiple raspberry pi nodes.
On the master I use django(brain)+angular(web-ui)+pigpio-library to interconnect the master pi with slaves.
Basically using pigpio I can send from the master turn-on or turn-off signals to slave without any other tool.
- In my home configuration, I have 3 raspberry pi.
- All 3 are connected to the same network.
- 1st pi is master and the other 2 are slaves.
- 2nd and 3rd raspberry pi are slaves, and only have pigpio service installed
- this give me centralized interface to n pi`s connected to my network
- downside it that our app is not yet able to do complex things:events, tasks, etc. So if I want to connect a PIR to my master and based on this trun on a LED on slave`s gpio, I cannot!
In node-red or home-assistant, both use mqqt to send or receive information regarding sensors or manipulate gpio`s.
Can I have with node-red a centralized interface installed ok master pi, and from there to act upon a gpio on slave pi?
thank you George
...ANSWER
Answered 2017-Nov-17 at 14:43You can use the node-red-node-pi-gpiod node on a central Node-RED instance to control GPIO pins on remote pi's.
You just need to make sure that pigpiod is configured to listen on the external interface and that the firewall will not block access.

I am trying to deploy my app to heroku and I keep getting this error message saying that it "failed to detect app matching ......." and the push was rejected. I followed the way it said on the heroku website and I keep getting stuck on only that git push heroku master part I have tried doing some research I couldn't find a solution.
...ANSWER
Answered 2017-Jul-19 at 05:50This means that a package.json file isn't checked into the root of your git project, so Heroku is detecting that it isn't a Node.js app. You can see this locally:
