Your Voltello app and the Link device (LinkPro or LinkZB) communicate via our cloud, which means that once you've connected them, you can control from anywhere via the Voltello App. The Link device communicates directly with your solar devices, like your inverter, meter and battery, and then passes this information to the Voltello system so that automated controls can be applied. 

Take a look below at a simplified diagram of how your controls from the Voltello app are sent through to your inverter & other solar devices.
