I have setup a single channel LoRaWAN gateway connected to the crowed source LoRa network The Things Network.
Hardware used is a Raspberry Pi and a Dragino version 1.4 (3.3V) Arduion HAT with a SX1276 chip. Got it via AliExpress. Credits to LogMaker360 for the video.
I had today to change the TTN server address to 40.114.249.243
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.
He also has a gateway board for the Raspberry to use as gateway to talk to wireless nodes such as the Funky and emonTX, JeeNode, etc

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.

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.
Ubidots offer a free service for up to 5 measurement values.
My setup is Nexa temperatur and humidity sensors that report to a Tellstick connected to Raspberry. Here is the setup:
sudo apt-get install python-setuptools $ sudo easy_install pip $ sudo pip install ubidots
Using the api to post data in is only a few lines:
from ubidots import ApiClient
import random
#Create an "API" object
api = ApiClient("4785d3be6f45a6102xxxxxx75efb16a6f9b9c")
#Create a "Variable" object
test_variable = api.get_variable("56294a1xxxxxxx27c3c69d")
test_value = random.randint(1,100)
test_variable.save_value({'value':test_value})
Here is my outside temperatur chart based on a logging once per hour:
This is a link to David Hunt’s DYI very interesting project to build a GSM Phone based on a Raspberry Pi. The project can inspire to various implementations where GPRS may be needed, also for situations where you may need to run on battery.
Here is David’s run-down of component costs. Please be sure to check out his video demo as well.
Costs:
Total: $158
From the Splunk blog there is a simple step-by-step instruction of how to install a forwarder of data from you Pi into a Splunk instance on a Mac/PC.
It could be to capture log data from GPIO connected sensors.

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:
You should of course replace the IP address with the one for your RPi). You may omit user & pass for a local installation to avoid a login-page.
Involved components:
I have now decieded to try the HomeAutomation 2.0.2 created and published as open source. On the Telldus forum, there is a thread covering HA.
Update: I am putting this on hold since I’m now deployed the remotestick-server, see this post.

The Adafruit.com site is both a good site for purchasing your Raspberry as well as a welth of components for any type of project.
There is as well a lot of very good tutorials, but this time I would like to hint of their Alpha-version of a very nice Python development environmen.
The Adafruid WebIDE installes on the Pi and then you access it via your browser. Key advantages:
The IDE even has event management feature that allow you to schedule program snippets to run at specific intervals.
