Can I link the HomeWizard  EnergieLink from the HomeWizard (Gateway) to the Link?

It is not possible to connect an EnergyLink to the Link at this moment. For insights into energy consumption, look at HomeWizard Energy. (dutch only)

How to measure energy with the Link?

It is possible to see the energy consumption of a single outlet or device by connecting an 'Smartwares Connected Energy Socket SH8-90901' to your Link. With this product you can measure the energy consumption of devices up to 3500W.
