The problem
Most sites can't see what their equipment is doing.
Your data is trapped in different vendors' systems
Breakdowns are discovered after they happen
Energy waste stays invisible until the bill arrives
How it works
From machine to insight in three steps.
- Step 01
Acquire
En-Stream gateways collect data from any PLC, meter, VFD or sensor.
- Step 02
Communicate
Data travels encrypted to the platform over Ethernet, Wi-Fi or GSM.
- Step 03
Analyze & Optimize
AI spots trends, predicts failures and sends alerts before issues become downtime.
Platform
One energy management platform for every reading on site
Watch power move from solar, grid and generator into your facility, live. See which source carries the load at any moment.
Compare what you use with what you generate. Spot the gaps that drive up your bill.
Track boiler gas, fuel and compressed air next to electricity. One view for every utility on site.
Measure CO₂ emissions from every energy source. Report progress with data you can trust.
Set your own alarm conditions for any reading. The right people are notified the moment something drifts.
Build views for each role, from plant floor to management. Each team sees the readings that matter to them.
Connectivity
Works with the PLCs, meters and VFDs you already have.
En-Stream is vendor-agnostic. Legacy and modern equipment connect without costly revamps.

FAQ
Energy monitoring FAQ: questions buyers ask us.
Do I need to replace my existing equipment?
No. En-Stream gateways connect to the PLCs, VFDs, motors, meters and sensors you already run, including legacy equipment.
Which gateway is right for me?
The ES-IGW-B1 collects data from existing meters and controllers. The ES-IGW-E1 adds analog and digital inputs, CAN bus and relay outputs for sites that need direct sensor inputs and equipment control.
Which protocols do you support?
MQTT, HTTPS, Modbus TCP and RTU, Ethernet, RS485, RS232, CAN bus, and digital and analog I/O (0–20 mA / 0–10 V). Gateways connect to the platform over Ethernet, Wi-Fi or GSM.
Hosted or on-premises?
Both. Use En-Stream's hosted platform, or deploy on your own on-premises servers.
How is our data secured?
Data is encrypted in transit with TLS and encrypted at rest. Role-based access limits what each user sees, and audit logs record every action.
How long does installation take?
Most sites take 1–3 days on site: mounting gateways, wiring meters over RS485 or Modbus, and commissioning. Dashboards go live in the first week. Larger plants and multi-site rollouts are installed in phases, so production never stops.
Do you work outside Pakistan?
Our engineers install and support En-Stream across Pakistan. For sites outside Pakistan, contact us to discuss remote deployment.
What is an industrial energy monitoring system?
It measures electricity and other utilities at the meter, machine and source level in real time, then shows where energy goes, what it costs and when something drifts. En-Stream does this with its own gateways and an AI-powered platform.
How much does an energy management system cost?
It depends on the number of meters and machines, which gateways you need, and whether you choose hosted or on-premises. We size every quote to your site and send it within 2 working days of a 30-minute call.
Can I monitor solar, grid and generator together?
Yes. The Energy Flow view shows power from solar, grid and generator into your facility live, and Consumption vs Generation compares what you use with what you produce.
Can En-Stream track compressed air, boiler gas and fuel?
Yes. The Utilities view tracks boiler gas, fuel and compressed air next to electricity, so every utility on site is in one place.
How does predictive maintenance work?
En-Stream watches readings from motors, VFDs, pumps and other equipment. Its AI spots trends that come before a failure and alerts the right people early, so you can plan maintenance instead of reacting to breakdowns.
Can I report CO₂ emissions?
Yes. CO₂ Tracking measures emissions from every energy source on site, so you can report progress with measured data instead of estimates.
