Forget Me Not Design Challenge

In this post I will be presenting a final wire up of the system I developed for Forget Me Not challenge. So now this is what I have at home. I have my raspberry pi hosting openHAB and running a couple of other scripts in my Living Room, beagle bone black at kitchen, Intel Galileo at bedroom and TI's Connected Launchpad for the outside devices.   Now the things are simple in openHAB. I have four pages in openHAB corresponding to each area. I have placed the enocean reed switches in the front ...
In my last post, I showed how we can connect individual room controllers to the main hub( raspberry pi ) using a home network and also how Paho MQTT library comes handy for the communication between them. Basically a room controller takes care of all the controlling functions of devices in a room. Each one runs linux and have a python script using Paho MQTT library for networking and GPIO libraries for controlling the devices. Now my system have the added advantage that openHAB doesn't have to d ...
"If something works for some one, it doesn't mean that it will work for you" -- this is the hard lesson I learned in past weeks. I was caught in between some personal matters for last two weeks and didn't gave much time for the challenge. I'm so ashamed that I tried to fix something here and there for two weeks and all I know now is a thousand ways how it will not work . So this is what basically happened. In my project, there are these 'room controllers' which will be managing all the devices i ...
Let me start with asking you a question. How many of you uses facebook messenger in your smart phone? Most of you will. But how many of you know that you are getting your notifications through MQTT protocol? Probably not many. I came to know it just a few days ago. Why FB is using MQTT in their messenger? Now a days, if you go to any IoT related sites, you willl be seeing this term MQTT quite often. It seems like MQTT is the HTTP of IoT age. But then I asked a question myself -- why should I cho ...
In last post, we looked how to dweet enocean sensor data from raspberry pi using Enocean-Py library and view it real time in your desktop using 'desk_viewer.py' script. In this post, we'll see how to dweet from enocean data from openHAB and also how to control your device from internet. With this step, we are stepping a little more towards the dream of 'internet of things'. I have my enocean pi connected to my rPi and my rPi is having a working internet connection. What we are going to do is to ...
Everybody is tweeting!! I like that. It keeps me updated about whats happening around. Unlike big brother FB, i don't have to worry whether to Like or Share or Comment for a post or just do nothing. If I want to spread the word, just retweet. Simple, elegant! But what happens when all these devices started tweeting. Ohh...they are gonna flood the place. I noticed first the trend around some four years( or before that? ) when people started interfacing a moisture sensor to an arduino with wifi sh ...
In my last post, I introduced Dweet.io and explained how to dweet from your raspberry pi. in this post, I'm going one step ahead and wiring together my Enocean-Py library with dweepy and start dweeting my Enocean sensor data. Let's start dweeting The whole idea is this - my raspberry pi, my first python script will first decode a received radio telegram with Enocean-Py and extract the rocker switch state. Then it will dweet this information to the public. On my desktop, I'll be running a secon ...
Happy news this week is I received raspberry Pi, EOP 350 programmer and the extra serving of Pi . I have already tested openHAB and enocean Pi with my PC, so now it's time to move everything to raspberry Pi. These are some pics of my Pi mounted with enocean Pi, running openHAB. This tutorial assumes that you already have a working Pi installed with latest version of raspbian operating system with a working internet connection. The standard raspbian 7.0(Wheezy) also includes java components ...
In last post, I explained how I was able to connect Enocean Pi to a laptop and configure it with openHAB. It worked pretty well, but I had a hard time decoding IDs of enocean devices to configure in openHAB. I managed to get hexdumps of the serial communication happening with a serial monitor and spend some time with Enocean Serial Protocol document and Enocean Equipment Profile document to finally figure out how to extract device IDs from the hex dump. As a part of my course curriculum, now I'v ...
This is quick post on how to interface enocean Pi to your laptop and use it with openHAB running from your laptop. In this post, I'm using Ubuntu 14.04 as my OS with openHAB 1.5 installed.   As my raspberry pi will be arriving a little late, I set out to find out whether it's possible to interface enocean pi to my laptop. Searching on google I found that Enocean Pi module uses only four pins from raspberry pi - VCC 3.3V, TXD, RXD, and GND. It immediately came to me that with an USB to TTL s ...
"Shipments are a little delayed" -- this is a mail I got a few days ago from e14. Okay...but waiting until my rPi arrives to start working on the project is not a good idea. So I decided to test openHAB with my laptop itself. My laptop is running Ubuntu14.04 64bit on an i5 2.4GHz with 4GB RAM. So the performance of openHAB in my laptop cannot be compared to raspberry pi by any standards. But installing and working with openHAB in more powerful system is always good -- it gives a good understandi ...

This post contains the link to my blog posts for Forget Me Not challenge. I'll keep updating this page as and when I posts new blogs. The challenge runs untill 24th Oct 2014. So you can expect atleast  a new post every week till then.   Index   [FMN#00] My Proposal : In this post, I discusses about the proposal for challenge, architecture of the proposed system and introduces a few tools I'm going to use. [FMN#01] : Ubuntu, meet openHAB. This post explains about my first experien ...

[FMN#00] My Proposal

Posted by vish Aug 3, 2014
Hello all, This is my first post in 'Forgot Me Not' challenge. I'm one of the FMN challenge finalists, not the Top 15, but one in the Lucky 5 gang. So I'll be receiving the basic kit -- Raspberry Pi B+, enocean sensor kit and an enocean Pi . And this is going to be first rPi. I'm going to deviate from my original project proposal due to some budget constrains. I'll have to cut down my shopping list and include some into my lending list. The idea will still remain the same, but I'll be dropping a ...
