Description

An energy display is an easy way for a user to view all the information collected by the sensors around their home. This application needs to support multiple protocols such as Zigbee and IEEE802.15.4 in order to be able to share the information with all the sensors around it. The Sigfox protocol could also be included in the features of this display.
