Key capabilities#

  • Real-time status: Generator operating state, voltage, frequency, and load
  • Exercise scheduling: Set weekly exercise schedules remotely via app or web
  • Fault alerts: Push notifications and email alerts for faults and service reminders
  • Runtime logging: Historical runtime, start events, and exercise records
  • Maintenance reminders: Oil change, filter, and coolant service intervals
  • Multi-platform access: Web portal, iOS app, Android app

OnPoint service notes#

During annual maintenance visits, our technicians verify OnCue Plus connectivity and confirm that the monitoring module is communicating with Kohler's cloud servers. We check that exercise schedules are active, alert contacts are current, and historical logs match the physical runtime meter. For customers who prefer independent monitoring, we can install Gen-Tracker or Omnimetrix alongside or instead of OnCue Plus.

Frequently Asked Questions

Which Kohler generators are compatible with OnCue Plus?
OnCue Plus is natively integrated with all current-production RCL residential liquid-cooled generators (24RCL through 60RCL) via the RDC2/DC2 controller. It also works with KCS Series industrial ATS units equipped with the MPAC 1500 controller when paired with a Kohler generator. RCA air-cooled residential units require the optional OnCue Plus monitoring module for connectivity.
How does OnCue Plus compare to Generac Mobile Link?
Both platforms offer web and mobile app access with real-time status and alerts. OnCue Plus provides deeper integration with Kohler's RDC2/DC2 controller, including direct exercise scheduling and detailed fault code reporting. Generac Mobile Link uses Wi-Fi connectivity while OnCue Plus supports both Wi-Fi and cellular options depending on the installation.
Can OnCue Plus help with NFPA 110 compliance documentation?
OnCue Plus logs every exercise event, runtime session, and fault occurrence with timestamps. This data can be exported for NFPA 110 compliance reporting, providing the exercise frequency and duration documentation required by the authority having jurisdiction (AHJ).
Does OnCue Plus work with non-Kohler generators?
OnCue Plus is designed specifically for Kohler generators and ATS equipment. For mixed-fleet monitoring, third-party platforms like Gen-Tracker or Omnimetrix provide OEM-agnostic monitoring via Modbus or dry-contact integration.
