Hi Chris,
It is my hobby to design stuff for my home automation. The sensor that Alwas use is the foundation of what I am making today.
Currently, I am making Arduino shield connected to my sensors. Here is some example of what I am making. It is an Arduino UNO shield.
I also have Arduino Mega 2560 and Arduino Due shield.
Now, what Alwas need is much simpler. He need to connect simple Analog, Digital sensor. The shield require an Arduino. Adding Arduino is to handle much more complex sensor. Or, Arduino is sometime a good choice if you want to connect a lot of sensors.
Here are some of the demo video what the shield can do. I apologize the demo is using different hub but it is very similar to Smartthings. I maintain DTH for both hubs. I am trying. Sometime, the availability of the demo or feature lag on one hub compared to the others. But, the video should illustrate what the idea is.
If you need more information, just PM me.
Thanks
Iman
