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 spreads it in the middle of Bluetooth Mesh with at least one Calex Outdoor device in the garden. The Calex devices communicate with each other and the strong connection as long as they remain within range of each other. This way, you can considerably expand the range for your garden without this being at the expense of the connection. The Calex Link is fully extended with the Calex Smart App and works easily via Amazon Alexa and Apple's Siri.
