What is a Remote Monitoring System?
(And Do You Need One?)
If you've searched for "remote monitoring system" you've probably already got a problem to solve — rising energy bills, equipment you can't keep an eye on, or a compliance deadline that's starting to feel very real. This guide explains exactly what a remote monitoring system is, how it works, and whether it's the right solution for your site.
What is a Remote Monitoring System?
A remote monitoring system is a network of sensors installed on equipment, circuits or building systems that continuously collect data and send it to a central platform — accessible from anywhere, on any device.
Instead of walking the factory floor with a clipboard, or waiting for a monthly energy bill to tell you something went wrong three weeks ago, a remote monitoring system shows you what's happening right now.
Modern systems like Enerlytix-Scout monitor:
Electrical energy consumption (kWh, cost, CO₂) at machine or circuit level
Current and voltage to identify power quality issues
Temperature in cold rooms, pipework or environmental spaces
CO₂ and air quality in occupied buildings
Machine utilisation — when equipment is running, idle or down
How Does it Actually Work?
Most remote monitoring systems follow the same four-step architecture:
01 — Sensors
Small devices are installed directly on the equipment or circuit being monitored. For energy monitoring, this typically means CT clamp sensors that clip around existing cables — no rewiring, no shutdown required.
02 — Wireless Communication
The sensors transmit data wirelessly. Many industrial systems use LoRaWAN (Long Range Wide Area Network) — a technology designed specifically for sending small amounts of data over long distances (up to 15km) without needing WiFi or your site's IT network.
03 — Gateway
A single gateway device receives the data from all sensors and forwards it to the cloud via a built-in SIM card. One gateway can handle hundreds of devices.
04 — Cloud Dashboard
Data is decoded and presented in a secure online platform — showing live readings, historical trends, alerts and reports that anyone with access can view from a phone, tablet or desktop.
Why Not Just Use Your Existing Meters?
Most sites already have an electricity meter — so why go further? The problem is that a single site meter only shows you total consumption, usually in 30-minute intervals. That tells you how much energy you're using, but not which machine, which process or which time of day is responsible.
It's like getting a phone bill that just shows your total minutes used, with no record of who you called or when. A remote monitoring system gives you the full itemised breakdown.
A remote monitoring system breaks that down to machine level. You can see that your compressor accounts for 34% of your total energy bill, that it's still running every Sunday morning when the site is closed, and that it's drawing slightly more current than it should be — which might indicate a developing fault.
Do You Need WiFi?
This is one of the most common questions we get — and the answer is no. Systems built on LoRaWAN technology, like Enerlytix-Scout, use a dedicated wireless network that is completely separate from your site's WiFi or IT infrastructure. A SIM card in the gateway sends data to the cloud directly.
Security — your operational data never travels through your corporate network
Simplicity — installation doesn't require IT sign-off or network configuration
Coverage — works in outdoor plant, remote buildings and basement plant rooms

Who Actually Needs One?
Manufacturers with energy-intensive machinery (compressors, motors, chillers, HVAC)
Food and pharmaceutical sites needing continuous temperature compliance records
Multi-site businesses wanting visibility across all locations from one platform
Organisations under compliance pressure from ESOS, SECR, ISO 50001 or net zero targets
Sites with unexplained energy costs or frequent equipment breakdowns
If your energy bill is more than £30,000–£40,000 per year, there is almost certainly waste that a monitoring system would find. Most sites recover the cost of installation within 6–18 months through energy savings alone.
