The Brultech ECM-1240 is a whole home energy monitor that uses current transformers (CT's) in your home's electrical panel. Brultech provides some nice example installtions on their website. The ECM-1240 communicates back with a computer via an RS-232 port or an optional XBee wireless card to communicate on a Zigbee mesh network. You can see different Brultech communication options on their page here.
The Efergy Elite is a home energy monitor that uses circuit transformers (CT's) in the home's electrical panel to measure current entering your home. The current transformers plug into a transmitter that transmits (up to 230' at 433 MHz) energy data to an energy dashboard. The homeowner selects the voltage the home uses and a simple (simple because power factor is omitted) power calculation results in the home's wattage consumption.
Installation is very simple but an electrician should be contacted for those uncomfortable working around electricity.
The TED 5000 is a home energy monitor that monitors your entire home's electricity consumption. Unlike energy monitors that mount on your home's electrical meter, the TED 5000 uses current transformers (CT) and a measuring unit (MTU) to mount inside of your home's electric panel. Installing the TED 5000 is straight forward but an electrician should be used for those uncomfortable working with electricity.
The Kill-A-Watt EZ is the big brother to the Kill-A-Watt. It has all the features of the Kill-A-Watt but also includes the ability for users to energy their kWh rate so they can see what appliances cost them to operate (without having to do the math themselves). Power cost information is retained by a battery backup.
The PowerCost Monitor (PCM) is a whole home energy monitor that "reads" your electrical meter on the outside of your home.
The Black & Decker EM100B Energy Saver Series Power Monitor is the PowerCost Monitor manufactured by Blue Line just rebranded by Black and Decker. It looks like Black & Decker is no longer branding this product. The only tool under the energy category of the home and office section of their website is the thermal leak detector.
The UFO Power Center by Visible Energy is a power strip on steroids. It acts as a power strip, home energy monitor and electric appliance timer all in one.
From the UFO Power Center How It Works section:
The eMonitor by Powerhouse Dynamics is a whole home circuit-level energy monitor. There are 3 different versions of the eMonitor: 4-14, 4-24, and 4-44. The second number after the dash represents the number of circuits that can be monitored.
From the eMonitor website:
"Powerhouse Dynamics has created a Total Home Energy Management solution that lets you manage all uses – and sources – of energy in your home. Total Home Energy Management:
EcoDog's FIDO home energy monitoring system monitors individual circuits in your home at your electric panel and uses power line communication to get the data back to your computer. Unlike other monitoring systems that send data over the internet, this data is is sent to a software program that resides on your Intel-compatible PC running Windows (not too easy if you have a Mac). This means there is no monthly fee for software hosting, but also means it may be difficult to access your home's energy data from a mobile app or another computer.
The Energy Owl is a home energy monitor that attaches to the meter outside your home and displays data through a PC interface.
