Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ignition

  • Requires real engineering to implement; it is a platform rather than a finished application
  • Steep learning curve, and Inductive Automation runs its own training programme because of it
  • Self-hosted and self-supported by default, so plant IT carries the availability burden
  • Module-based pricing means the entry figure is rarely the final one

Wattwatchers EMS

  • Requires hardware installation at each monitoring point, increasing total cost of ownership
  • Built for small to medium portfolios; scaling to large portfolios may present usability challenges
  • Limited to energy monitoring; not a comprehensive building management system

Answered from the vendors’ own pages

Ignition: What does Ignition cost?

It publishes per-server module pricing with unlimited clients, tags and connections, so cost does not scale with how many people use it.

Wattwatchers EMS: What data does Wattwatchers monitor?

Wattwatchers measures consumption at the device or circuit level in real-time, identifies equipment inefficiencies, and streams data through cloud dashboards for detailed energy consumption pattern analysis.

Source
Ignition: Why does unlimited-client licensing matter?

Traditional SCADA is licensed per tag or per screen, which turns adding an operator terminal into a purchase. Ignition removes that ceiling.

Wattwatchers EMS: What web-based tools does Wattwatchers provide?

Wattwatchers provides Fleet Management for fleet overview and device health, an Onboarding tool for smartphone-based device configuration, and a Dashboard for customers to view sites and data.

Ignition: Is it a finished application?

No, it is a platform. Screens, tags and logic are built for the specific plant, which is real engineering work.

Wattwatchers EMS: What is the mydata.energy app?

mydata.energy is Wattwatchers' mobile application available on iPhone and Android that provides real-time energy management and monitoring for homes and small businesses.
