Mercator Ikuü features a range of products, some of which need a hub. The Mercator Ikuü Wi-Fi range doesn’t need a hub, products can simply pair directly to your Wi-Fi router. The Mercator Ikuü Zigbee range does require a hub, but you also get the additional benefits of Zigbee. It doesn’t matter if a product is Zigbee or Wi-Fi, all Mercator Ikuü products work together and appear in the app together.
