What is 1PowerControl?

The control layer between your switchboards and your decisions.

1PowerControl (1PC) is an industrial automation platform by E-MAAN Digital that connects Modbus RTU energy meters and power analyzers to a cloud dashboard for real-time energy monitoring, alarms and reporting. It is built for factories, commercial buildings, hotels, hospitals and data centres, and is part of the 1Suite product family alongside 1HRIS, 1FieldApp and 1WA.

Four pillars · one platform

Start with energy. Automate everything that consumes it.

Every pillar runs on the same gateway, cloud and dashboard, so adding the next one is a configuration, not a new project.

How it works

From switchboard to screen in four hops.

How does 1PowerControl collect energy data? Meters report over Modbus RTU to an on-site 1PC gateway, which publishes encrypted readings to the 1PC cloud, where they become dashboards, alarms and reports.

Energy meters connect over RS-485 Modbus RTU to the 1PC gateway, which sends data over MQTT and TLS to the 1PC cloud, feeding dashboards, alarms and reports.412.6PM-01315.3PM-02218.0PM-03RS-485 · MODBUS RTU1PC GATEWAYpoll · buffer · encryptMQTT · TLS1PC CLOUDstore · analyseDashboardsAlarmsReports
  1. 01

    Measure

    Modbus RTU energy meters and power analyzers on each incomer, feeder or machine. We reuse yours or install new ones with CTs.

  2. 02

    Collect

    Meters share one RS-485 bus. The 1PC gateway polls every register every second and buffers data if the internet drops.

  3. 03

    Transmit

    Readings leave over an outbound-only, TLS-encrypted MQTT link. No inbound ports, no VPN, no IT headache.

  4. 04

    Act

    Live dashboards, threshold alarms and scheduled reports for engineers, finance and management.

The dashboard

See every kilowatt, the second it moves.

  • Live demand against your contract limit, with alarms before you cross it
  • Per-phase current to spot imbalance and overloaded feeders
  • Cost per feeder, line or tenant, updated every second
  • Power factor and THD so penalties and failing motors show early

Outcomes

What changes when energy is automated.

Monitoring is only the start. The value comes from the decisions and automatic actions it makes possible.

  1. 01

    Cut maximum-demand charges

    Alarms fire before demand crosses your contract limit, so loads can be shed or staggered in time.

  2. 02

    Find waste you are paying for

    After-hours baseload, idle compressors and leaking air show up as clear patterns, not guesses.

  3. 03

    Make every department accountable

    Cost allocated to lines, floors or tenants each month, from metered data rather than estimates.

  4. 04

    Catch faults before failures

    Phase imbalance, low power factor and rising harmonics flag stressed motors and capacitor banks early.

  5. 05

    Report without spreadsheets

    Scheduled daily, weekly and monthly energy reports for management and sustainability (ESG) reporting.

  6. 06

    Prove the savings

    Before-and-after comparisons verify the return on every efficiency project you fund.

FAQ

Questions, answered

What is 1PowerControl?

1PowerControl is an industrial automation platform by E-MAAN Digital. It reads energy meters and power analyzers over Modbus RTU, sends the data securely to the cloud, and gives plant and facility teams real-time dashboards, alarms and energy reports. Energy monitoring is live today; solar, HVAC and BMS modules follow.

Do I need to replace my existing energy meters?

Usually not. If your meters or power analyzers have an RS-485 Modbus RTU port, the 1PC gateway reads them directly. Where a panel has no meter, we supply and install Modbus RTU energy meters with suitable current transformers.

How long does an installation take?

A typical site goes live within days, not months. After a site survey we wire meters onto an RS-485 bus, install the 1PC gateway, map the meter registers and commission the dashboard. Most of the work happens without shutting down production.

Is my plant data secure?

The gateway only makes outbound, encrypted connections, so no inbound ports are opened on your network. Data is transported over TLS, and dashboard access is restricted to the users you approve.

Which industries is 1PowerControl built for?

Factories and process plants, commercial buildings and malls, hotels, hospitals, data centres, cold storage and warehousing: any site with LV panels, high energy bills and a need to see where the power goes.
