How to use the groov RIO EMU

Learn more about how this energy monitoring unit works with the newly published groov RIO EMU user's guide.

When introduced in 2020, the groov RIO series introduced a new kind of I/O product: edge I/O. Communicating data to other systems doesn't require a PLC, PAC, or IPC. Instead, this intelligent, distributed I/O includes security, data processing, and networking to meet the needs of IIoT projects independently.

Then we introduced the groov RIO energy monitoring unit (GRV-R7-I1VAPM-3), or RIO EMU for short, to bring the same level of connectivity to projects that require power and energy data acquisition and communication. Whether you're already using groov RIO for energy monitoring or still researching your options, the new groov RIO EMU User's Guide can help you understand its full capabilities and features.


This user's guide shows you how to assemble, configure, commission, and maintain a groov RIO EMU. groov RIO EMUs can monitor the electrical energy used in your facility and then deliver that data to online software applications, control systems, and business systems—using your existing wired or wireless Ethernet network. groov RIO EMUs give you the detailed, real-time data you need to analyze power and energy consumption and reduce energy costs.

The guide explains how to:

  • Mount and wire a groov RIO EMU
  • Complete the first configuration steps after you turn it on
  • Set up cybersecurity features
  • Connect it to a network or multiple networks
  • Configure groov RIO EMU to correctly measure your electrical load(s)
  • Enable MQTT 
  • Maintain your groov RIO EMU by applying firmware updates, performing periodic backups, and basic troubleshooting, including how to conduct an OptoRSS (Remote Support Service) session


How can RIO EMU help you?

  • Monitor category III 3-phase AC power up to 600 V in Delta or Wye configurations
  • Capture 18 data values per phase—voltage, current, true power, power factor, and frequency—plus 10 3-phase totals
  • Measure power and energy at the point of use to detect downtime predictors like high power consumption
  • Easily share real-time data with analytics software, databases, and dashboards using the built-in MQTT/Sparkplug client
  • Secure the system and data with user accounts, configurable firewall, TLS certificates, HTTPS, and VPN client
  • Quickly power for standalone operation with 802.3af PoE Class 0 switches or use 10-32 VDC line power

In addition to the user's guide, the following resources are also available to help you get started with this plug-and-play solution:
