It's hard to believe it's been almost 3 months since the start of the Forget Me Not design challenge. As the challenge is drawing to a close, it's a good time to reflect on my performance and progress.   This is my first involvement in a design challenge for Element14. I had mixed feelings when I was chosen as one of the 5 bonus competitors: although there was happiness at having my idea validated, I was disappointed to be starting on the back foot, so to speak, when compared to the others ...
Most alarm systems these days use a keypad on the wall. Before you leave the house, you punch in your 4-digit code to arm the system. When you return, you enter the code again to disarm the system. This approach is limited in a number of ways.   The keypad needs to be wired into the system and placed by the entrance. If you have multiple entrances, you will often require multiple keypads (one at each exit). It's also difficult to track who is arming/disarming the system. Sure, you can issu ...
I haven't seen this mentioned yet, so I thought I'd write a quick post.   openHAB configuration is controlled by a number of text files, which define the various rules, items, and sitemaps. The format is quite particular and editing directly on the RPi can be tedious.   Initially I was using the openHAB designer on my laptop to configure openHAB. It runs on Windows, Linux, and OSX, providing a GUI with which to modify the various files. By also running openHAB on my laptop, I could p ...
You may have wondered about the lack of updates on my security system for the Forget Me Not challenge. I apologise for this, but want to provide some explanation.   Life has certainly been conspiring against me for this challenge. First I had my car broken into and my laptop stolen. Then I had my fair share of shipping delays and lost parcels. And then recently a close friend passed away suddenly. With all the events it's been difficult to make headway and also to keep up momentum.   ...
I am attempting to get my challenge back on track after a few hiccups. My car is now fixed but insurance has yet to replace my laptop so my progress will still be slow. I'm also yet to receive the EnOcean Pi and sensor kit, so can't make any headway on that front.   This means my tasks have to shuffle around a bit, and I will work on some aspects of my project that were "time-permitting" rather than "mission-critical".   I currently have OpenHAB running on my RaspberryPi B+ but it wa ...
So the good news is I received my Raspberry Pi B+ today, along with the EnOcean EOP350. I haven't received the EnOcean Pi or sensor kit yet.   The bad news is my car was burgled 2 days ago and among the things taken was my personal laptop. This is going to hurt my challenge quite badly, as I have lost not only some design material but it's going to take some time to get up and running again.   I can probably get some things done after hours on my PC at work, but it's not ideal... ...

The waiting game...

Posted by tekmeister Aug 18, 2014
Just a brief update:   I'm in a bit of a holding pattern, still waiting on my basic kit to arrive. According to UPS it is due in my hands tomorrow.  I've also been trying to finish some of my other (real-life) tasks so that when the package does get here I can devote time to getting familiar with it.   Up to now I've just been experimenting with my older Model B Raspberry Pi and playing with OpenHAB. Also some reading up of EnOcean to explore the possibilities of re-programming ...
If you've followed my earlier post, you'll have a Pi with up-to-date packages, and you'll know how to log in.   The next step is to get openHAB up and running.   Java Check If you are running Raspbian, java is already pre-installed.   Check this by running java -version   Copying files to the Pi Probably the easiest way to transfer files to/from the Pi is to use SFTP - this is enabled by default on Raspbian. I use the free Filezilla client (WinSCP is another popular free ...
Getting started with Linux and the Raspberry Pi can be daunting. Hopefully this post helps alleviate the pain for those just starting out.   Before you start, I'm assuming you already have a Raspberry Pi (RPi) and an SD card (microSD for the model B+). Life will be a bit easier if you have a monitor and keyboard that you can use with the RPi, although it's not essential.   Download an OS image Firstly you want to choose a Linux image. I normally use the Raspbian distribution. You can ...
This morning I woke up to find an email informing me that I was chosen to receive a basic package for Forget Me Not challenge.   I'm excited for a multitude of reasons. Firstly I get a reason to play with the EnOcean energy harvesting sensors. They have been available for a number of years and I've been aware of them for a long time, but I've yet to play with them. There's still something magical about sensors that are self-powered.   This challenge is also providing me with some mot ...
