This page contains a selection of files which can be used to support various WEL capabilities. 
Right-click a link to download the document or program.

Current Release

On 5/11/2006 the WEL system underwent two significant changes. 

  • The WEL PCB was upgraded to Rev 3.2, to include a "1-Wire +V" supply switch.
  • The WEL Software was upgraded to Rev 2.0 which included a more robust software update feature.

The files in this section relate to the current hardware and software release.
Scroll down to the Legacy Files section for manuals for prior hardware and software.

WEL User Manual 2.0. (WEL_User_Manual_2.0.doc)  [[an error occurred while processing this directive]]

This updated WEL Users Manual was created to address the 3.2 hardware and 2.X software.  This manual incorporates BOTH the User Guide and the Owner Setup manuals from prior revisions.  It also includes a primer on Network addressing as it relates to the WEL

LocateIP (LocateIP.exe)

If you use DHCP to automatically assign your WEL unit an IP address, you may not know how to find it with your browser.  Locate IP is a neat windows program that will go out and find the WEL, and let you see (and modify) it's IP address.

Image refresh scripts (WEL_images_refresh_scripts.doc)  [[an error occurred while processing this directive]]

Your live system image and trend graphs are created and displayed on an automatically-generated page on the OurCoolHouse server.  But if you have your on web site, then you may want to include them there as well.  Since the images are continually updated by the server, it makes sense to have them automatically refresh on your web page.  This file explains the best way to get your images to refresh automatically.  It's just some simple Java Script that can be cut & pasted into your page.

Standard Sensor Names (WEL_Standardized_Sensor_Names.doc)  [[an error occurred while processing this directive]]

One part of configuring the WEL is to give all your sensors names.  These names are used to define your system graphic and trend graphs.  This document suggests a standard naming convention.

Software Updates

User Software-Updates are possible on any WEL board running code version 2.0 or greater. 
This process requires you to download the UpdateManager program and the latest WEL binary image.  Once you have these files, follow the directions on the Software Update Page.

Update Manager program (UpdateMGR.exe)  [[an error occurred while processing this directive]]

This is a Windows XP program that locates the WEL on your network, then enables you to load the new binary image into the on-board flash.  The existing image can be saved on the WEL as a backup in case there is a problem with the new image.  Download this program and put it in a "WEL_Update" folder on your hard drive.  Add a shortcut to the program on your desktop.

WEL Binary Image Rev 2.3  (OCH_WEL_2.3.bin)  [[an error occurred while processing this directive]]

Thus update makes the WEB Post process more robust and corrects a bug that effects the Humidity Sensor.  Download this file and place it in the same folder as the Update Manager program (see above).

Legacy Files

WEL user guide. (WEL_User_Guide.doc)  [[an error occurred while processing this directive]]

This is the original WEL user guide.  It describes the hardware features of the 3.1 version board, and it's a general introduction to the overall WEL concept.  The manual describes the various functions inside the WEL, and it shows how to connect up the standard sensors to the WEL screw terminals.

WEL Owner Setup. (WEL_Owner_Setup.doc)  [[an error occurred while processing this directive]]

This document describes the process of setting up the WEL to post data, and setting up the OurCoolHouse website to record and display posted data.  The WEL screens are bas on Revision 1.X software.

The Web Energy Logger is an Internet Appliance that monitors a 1-wire sensor network, and posts live data to a web site for display and analysis. For more information, contact Thunder Bay Electric.
