Thanks to Element 14 and the sponsors for holding the Forget-Me-Not Design Challenge.  Also a big thanks to fellow Element 14 members for teaching me new ways of using OpenHAB.  I learned a lot of neat tricks, and I read lots of creative uses of technology from the other members.   For this design challenge, I set out to create a flexible home automation system with different types of wireless sensors.  This system also alerted the users via email or audio alarm when certain ...

I've been working on the laundry room portion of my home automation system.  I've worked out the OpenHAB automation portion.  I've changed the way I've been doing alarms and light indicators from my previous demos, so I thought others might be interested in seeing these parts.   Here's a graphic of what the screen looks like.       For custom icons, I found out how to do them from an OpenHAB forum member.  For the item definition, I'm defining a switch item ...
I've started work on a dog GPS prototype, but don't have anything to show yet.  The idea is to transmit the dog GPS location to OpenHAB, and have OpenHAB evaluate the coordinates.  If the coordinates are outside the yard, then play an audio alarm inside the house to let the people know the dog has wondered off.   I'd also like to do some physical computing by using an arrow mounted on a 360 servo to point to the direction of the dog.  This "dog pointer" would let you know ...
A couple of us are doing security systems for our project.  I thought this might be useful for putting time stamps directly on the OpenHAB screen.     Item Definition: DateTime itm_mailbox_time "Mailbox Last Updated [%1$tA, %1$tm/%1$td, %1$tI:%1$tM %1$tp]"   Sitemap: Text item=itm_mailbox_time   Rule: rule "update mailbox" when      Item itm_mailboxmqtt received update then      postUpdate(itm_mailbox_time, new DateTime ...
Started my prototype of these notifiers and tied it to OpenHAB:   1)  Dog Bark Sensor Using a $3 sound sensor similar to this one, you can sense loud sharp noises.  The ones with the larger diameter diaphragm might work better for sensitive sound detection than the smaller ones.  The one I have is a digital output device, and you use the pot to change the trigger level.     2)  Gas / Smoke Sensor You can get a MQ2 sensor for about $7.  It's sensitive ...
