groov Box

The groov Box is Opto 22’s Internet of Things (IoT) and operator interface appliance that provides visualization, data handling, and connectivity to automation systems, software, databases, and devices of all kinds.


With browser-based groov View, easily see and interact with data from sensors and automation systems, cloud applications, databases, web services, and more. Securely view the interface on any brand device, from a smartphone to a computer. groov View includes user authorization, trending, events, and notifications.

Data Handling

The key to IoT usefulness is getting the data out of where it’s trapped and into the systems and software where it’s needed. Built into the groov Box are Node-RED, an IoT rapid application development environment, and RESTful APIs to groov Data Stores. Add a groov Enterprise license and also use Ignition Edge® with OPC-UA drivers to Allen-Bradley® and Siemens® PLCs, plus MQTT/Sparkplug for efficient and secure industrial data communications.


Connect to all kinds of devices and systems to monitor and control them and move data between them.

  • Modbus®/TCP devices and Opto 22 groov EPIC and SNAP PAC controllers
  • Cloud applications, IoT platforms, on-premises databases, and external web services
  • Connect to Allen-Bradley and Siemens PLCs using OPC UA.
