Step 1: Learn About SIS and Decide What You Want to Do.

The first step is to understand fully what SIS is all about and the documentation that we have provided to assist you in ordering parts, building the SIS Hub, installing the firmware, planning your installation, and using the SIS Client app. The starting point is to read the document:


You must also read, understand and accept the Terms of Use, License and Disclosure:


<p>Well written instructions and a very nice project.</p><p>You may want to edit the final email address. It looks like &quot;shrimware&quot; should be shrimpware. Love your logo!</p>
<p>Thanks for noticing this - done!</p>
<p>I made one using 433 and 315 MHz receivers from Sparkfun. It made the assembled PCB look a little like the starship Enterprise.</p>
<p>Great ideas for a DIY security system.</p>
We have thought about using SIS for security, but we have reservations about the cheap sensors. These sensors are, in fact, sold on E-Bay as part of a security system, but they do not broadcast a low battery conditions. We think that the low price is worth it if the application is monitoring Grandma to see if she is OK at home (but not emergency response!). If a sensor battery dies, you would see a change in Grandma's daily pattern that would consistently leave out some room, in which case you would be inclined to check on the sensor's battery (and Grandma!).<br><br>Another reservation is that the separation sensors only trip when a door or window is opened. Most professional alarm systems keep track of door and window state so that you don't arm the alarm system with the back door or a window left open and then a burgler enters the house without tripping the alarm. Likewise, in SIS we cannot tell if Grandma closed (and locked) her door when she left the house, but we do know that she went out and is not at home.
