NetSmart “Web Bridge” for Online Access to data:

The Current Cost NetSmart WebBridge connects the EnviR Monitor directly to your router using an Ethernet cable, automatic uploading data to the website. You will be able to monitor your electricity use from any Internet connected computer or web-enabled phone or tablet. Included is one power supply capable of powering both the bridge and the EnviR display, a 4′ Ethernet cable, and 10″ display-to-bridge connector. The online monitoring is FREE for one channel, but if you want to monitor multiple channels we have a subscription service.  This allows for you to have a real-time online dashboard to observe the systems energy monitoring.  Using the Web Bridge through Current Cost allows you to have access to your data through their open API, so you can retrieve your data and use it with other applications if desired.  This hardware is specifically targeted to the Current Cost Website.  We have detailed Technical Instructions for Connecting the Web Bridge to  and for further connecting it to the free service (to parse the online data to your heart’s content).

Web Bridge Upgrade

For customers who are tracking their energy usage using a web bridge and want to upgrade their web bridge to monitor multiple channels (beyond the first free channel) we have a remote upgrade option.   This option only works for web bridges purchased after September 2011.   Web bridges purchased before that date must be manually mailed in (to England) for a flash upgrade.  There are two options, the NetSmart (3 additional channels for a total of 4), or the NetSmart Pro (9 additional channels for a total of 10).   You can purchase the upgrade here, but will need to send in a photograph of the serial number on the back of your web bridge so that we can proceed with the upgrade.
