Take control of your Kessil X-series lighting from your phone with the compact Kessil WiFi Dongle. It plugs directly into a compatible fixture's K-Link port and connects to the Kessil WiFi app, giving you a simple way to shape the light over your aquarium without adding a separate controller on display.

Why aquarists choose it

• Build a real daily schedule: set color and intensity through the day, including gradual dawn and dusk transitions, and use acclimation settings when introducing a new fixture or livestock.
• Manage multiple lights: connect compatible K-Link fixtures with the appropriate separately sold cables, then control a group from one dongle signal instead of adding wireless hardware to every light.
• Small footprint: the dongle plugs into the light, while an optional extension cable can help position it for reception in a canopy or crowded installation.
• Keep the fixture flexible: wireless control is a separate accessory, so the light itself remains useful if your control setup changes.

Compatibility and setup

Designed for K-Link equipped models including the A360X, A360XE, A360X Refugium, and A500X. Plug the dongle into a K-Link port on a powered fixture, install the Kessil WiFi app, and use the included QR code sticker during pairing. A 2.4 GHz WiFi connection is supported. For a multi-light system, choose the appropriate K-Link cables for the fixtures. The A160WE and A80 do not plug directly into this dongle; ask us about the proper controller or signal-converter arrangement before ordering it for those lights. The AP9X has built-in WiFi control and generally does not need this accessory.
