Introducing Growlink One

The Growlink One controller was designed to deliver the ultimate smart farm experience, featuring the highest quality components and processing power to coordinate hundreds of sensors and devices throughout your entire farm.

Growlink One controllers provide increased performance, capacity, productivity, and security to help meet the growing demands of high density sensors networks and sophisticated equipment control in a modern smart farm.

The base controller includes sixteen solid state relays with manual override switches for controlling external devices. Growlink controllers can be expanded with both wired and wireless I/O Modules for all sensor inputs and equipment control outputs.

The system is expanded as needed by simply adding additional controllers connected together through IP network. All control programs are executed from the controller. When you access the Growlink system onsite you you are communicating directly with the controller. When offsite you can access the controllers via the cload from a PC or Growlink iOS and Android apps.
