 __Summary Status__
-Phase 1 is done.  Mounted the enclosure on my wall and put it in service.  There are a few follow-up tasks but the HESA is working as designed.
+After experiencing a minor flood in the basement when the water softener turned on and the sump pump was not installed, I realized that my water softener runs without electricity.  So, I changed the design of the HESA to turn on power to a submersible pump when it detects water rather then turn off power to the water softener.  I also added graphing capability to the web page and made the code more reliable.

-===== Phase 1 =====
+===== Final Solution ====
-==== Description ====
-Create a device that will sense when water is spilling in to the basement.  The device will shut off power to the water softener and notify people that there is a problem.
 ==== Features ====
+  * Auto-startup on power up.
+  * Auto-recovery on program failure
+  * Status light that shows when pi is running.
   * Check for water in the basement.  If found:
-  * Shut off power to water softener
+    * Turn on power to submersible pump
-  * Send email to mail address
+    * Send email to mail address.  If internet is down, wait until it is up to send message.
-  * Auto-startup on power up
+    * Update local status page and internet database
+  * Send all clear email when water clears
+  * Read temperature and humidity in basement
+  * Store hourly readings to SQL tables on internet
+  * Check internet connectivity
   * All components mounted in enclosure that is mounted on wall and connected to 120v power
 ==== External Features ====
   * Email address that forwards mail to several email addresses as well as texting
+  * Web site that displays reading results in tabular and graphical form
 ==== Schematic ====
   * [[http://www.digikey.com/schemeit#kbo|Schematic]] stored on Digikey's website.

-===== Phase 2 =====
+==== Future Ideas ====
-==== Description ====
-Make the device more user-friendly and interactive.  Replace the Pi with a Beaglebone Black to make it able to connect to more things.  It should record daily data and statuses in a web-based database.  It should check the internet connection regularly.  If there are any non-standard conditions, alert the humans with email (if possible), lights, and sound until the problem conditions are gone.
-==== Features ====
-  * Record resistance readings multiple times a day in a web-based database
-  * Record system statuses in a web-based database
-  * Check internet connectivity
   * Display status on LCD screen
-  * Turn on light if internet connection is lost
-  * Turn on siren if flood condition recognized
-  * Repeat messaging every 24 hours
-==== External Features ====
-  * Web site that displays reading results in tabular and graphical form
-==== Components ====
-  * Beaglebone Black
-  * Green LED for normal operating conditions
-  * Yellow LED for internet lost
-  * Red LED for hazardous condition
-  * 16x2 display
-  * Siren
-  * Manual power switch for siren
   * Reset button
+  * Add a battery backup feature so the system can send alerts and shutdown gracefully in case of a catastrophe.
