Part of the PowerCost Series, the PowerCost Sensor Sensor & WiFi Bridge enables you to see your electricity usage in real time anytime from anywhere. This helps you be aware of and understand how your activities affect your energy usage. Many independent studies have proven that just knowing what you use can save you as much as 9%. Homes with electric heat and hot water experience even greater reductions, 14% & 17%. Why wait for the electricity bill - see in real time, exactly how much electricity you are using and make informed adjustments. Better information = better decisions = reduced energy usage = cleaner environment - It's that simple! The system consists of Blue Line's patented optical sensor unit, which gathers electricity usage information from your electricity meter and sends it to the PowerCost WiFi Bridge and then to EnergyCloud. You can track your usage over time and see trends. You can subscribe to one or more of our analytics cloud application partners to get a deeper analysis of your electricity usage patterns including right down to the appliance level. Now, not only will you know how much electricity your are using, but you can also determine where you are using it and how much it's really costing. EnergyCloud provides on-demand secure access from anywhere on the web including from your mobile devices. All of our CloudConnector devices, such as the WiFi Bridge, and our EnergyCloud application utilize the same level of encryption as your bank so your data is very secure.
