This is a hobby project by Martin Harizanov. A small Arduiono with usb and radio module.
This is v3 of my “Funky” Arduino clone, specifically designed to be small, with on-board radio module and for low power applications.
IBM is very active in both open source as well as in IoT. Here is a very nice tool for anyone into integration of any sorts of data flow.
I have it installed on one of my Raspberry Pi’s and it allow me to visually create integration mixing hardware and software.
Head of to http://nodered.org if you have yet see this.
Update, 25 Jan 2016: Node Red is included in the Jessie build for Raspberry pi. After struggling to get the GPIO to work with my old build, I decided to start from scratch. It was worth it. Node red is now only a menu option away, works like a sharm.
Extra benefit: The new GUI in Jessie (if you don’t decide for the slim down version) is very nice.
One example of what I included as my first experiment:
I have motion running with a camera overlooking my garden and street. As soon motion is detected it sends an event to a MQTT broker I’m running on another Pi. Then I have a node flow that subscribes to that topic and makes a http against my Sonos system to play a short notification indicating ‘car is arriving’. The Sonos api is based on node (min version 4) by jishi.
Using the api to post data in is only a few lines:
from ubidots import ApiClient
#Create an "API" object
api = ApiClient("4785d3be6f45a6102xxxxxx75efb16a6f9b9c")
#Create a "Variable" object
test_variable = api.get_variable("56294a1xxxxxxx27c3c69d")
test_value = random.randint(1,100)
Here is my outside temperatur chart based on a logging once per hour:
I wanted a clean and simple web interface to turn on/off my devices. It should also work on an iPhone or iPad.
I found that the remotestick-server created by Patrik Åkerfeldt was exactly what I wanted. It is based on the lean python framework Bottle.
The only tweek I have made so far is to filter my device listing to the devices beginning with underscore will not show up. The reason for is it to be able to define all my switches but only show the active one in the GUI.
Installation is simple:
Install the bottle framework with: sudo apt-get install python-bottle
