We measure in the field
Wireless IoT sensor networks, with no data cables and a few minutes' work per point: energy, temperature, pressure, air flow, vibration. Data captured at the source, where the process runs.
Efficiency starts with what you can measure. We turn data into action.
LemonLights is a Data Company: our sensors collect measurements at the source, and we turn them into clear numbers you can act on: quantitative and qualitative analysis of your industrial processes.

Measure, understand, decide!
We don't sell gut feelings: we build the chain that takes a physical quantity from the field to a documented decision. We handle every step, from the IoT sensor to the action.
We structure the data
A cloud pipeline turns readings into clean, reliable industrial time series, available in real time through dashboards and APIs.
We analyse with AI
Models and algorithms work on the time series; we deliver plain-language verdicts with the numbers to back them. Every alert names the machine, the time and the deviation in kWh.
From sensor to report, in four steps
-
1
IoT
Wireless sensors in the field read the quantities that matter — kWh, degrees, bar, vibration — and transmit them over LoRa.
LoRa -
2
Time series
Every reading lands in a per-machine time series, kept over time and exportable as CSV or via API.
-
3
Analysis
Models and algorithms compare every series with its expected profile and flag the deviations, in kWh and in euros.
-
4
Decision & action
Dashboards, alerts and plain-verdict reports: decide on the numbers and act on the process.
More data than any eye can read. That's what the AI is for.
Millions of readings a year per plant: four tasks are done by the models, below. The decision stays with you.
Anomalies in real time
Every endpoint produces thousands of readings a day. The models compare them continuously with expected behaviour and flag anomalies and drifts as they happen.
It anticipates, instead of recording
Forecasts on consumption, peaks and wear: maintenance comes when needed, power peaks are avoided beforehand, unplanned downtime becomes rare.
Correlations across departments
Energy, production, environment and maintenance on the same timeline: the cause of waste often sits in another department. A typical case: a compressor left running while the line is stopped.
It speaks plainly, it doesn't decide for you
The AI writes the first line of the report — the verdict — with the numbers underneath. The last word stays with those who know the plant. And it runs on our systems: no third-party AI services.
Energy efficiency is our trade. Electricity, our speciality.
LemonLights was born in industrial energy efficiency: we measure electricity machine by machine, compare it with what you pay and turn it into provable savings. The same method now covers compressed air, gas, water and production — but the heart is still the kWh.
Electricity, machine by machine
The core business: wireless wattmeters on every machine, real-time consumption, peaks, power factor and kWh per part. Efficiency starts here.
Savings proven, before and after
Every intervention — power-factor correction, load scheduling, out-of-threshold machines — is reported through specific KPIs: kWh per part, peaks avoided, less CO₂.
Compliance and incentives
Energy audits under Italian law, ISO 50001, energy-intensive user schemes, Transition 5.0: the measurement needed to prove efficiency and access the incentives.
Responsibility made cool
We work with manufacturers.
Every partnership has its own challenges and goals, but all the companies we work with chose to decide on data. Some have authorised us to say so:
