Notice: Nov 7 2016 14:00 EST.
WELserver.com is operational again after about 12 hours of data downtime.

An update was installed overnight that was not compatible with the server's Operating System version. It caused all scripts to go ofline. The update has been removed and the server should be back to normal operations.

If any WEL user perceives less than "standard" performance, they should contact me (phil.malone@welserver.com) and let me know what's different.

Thanks for your patience.

Simply put, the WEL (or Web Energy Logger) is a cost-effective way to map the energy flows in your home or office. It can help verify the performance of a solar thermal system, calculate the efficiency of a geothermal installation, or even prove that your home really is "Net Zero".

Not only does the WEL give you a window into your own energy environment, but you can be part of a bigger green community and share your live system-snapshot and trend-charts on the WEB in real-time.
