Making your garden smart has never been easier than with the Calex Smart Outdoor collection. The Calex Link picks up the local WiFi connection (2.4 GHz) and distributes it via Bluetooth Mesh with at least one Calex Outdoor device in the garden. The Calex devices are interconnected and spread the strong connection as long as they remain within each other's range. This way you can significantly expand the range of your garden without compromising the connection. The Calex Link is fully integrated with the Calex Smart App and also works easily via Amazon Alexa, Google Home and Apple's Siri.
