Energy management software

JETNIPAT Energy

See where your electricity goes. JETNIPAT Energy reads your meters over RS-485 or the network, keeps the history on your own server, and turns it into live dashboards, electricity-cost estimates, reports and alerts you can open from any browser on your network.

JETNIPAT Energy dashboard
Live dashboard: total power, today's energy against yesterday, the bill so far and 15-minute demand against your target.
Electricity cost and demand page
Estimated PEA TOU bill with on/off-peak energy, demand charge and Ft, updated through the billing cycle.
History page with load curves
Compare meters over any period, see peaks and totals, and export to CSV.
Solar page
Solar production against total use by the hour, self-use, baht saved and CO₂ avoided.
EnPI page
Energy per unit produced against a baseline, with savings tracked over time (in the spirit of ISO 50001).
Reports page
Daily and monthly reports as PDF or Excel, with on/off-peak energy and demand.
TV display (kiosk) page
A full-screen live display for a TV or control room — no login needed on the screen.
Meter management page
Add and manage Modbus RTU / TCP meters from the web, test the reading, and organise them.

Screenshots show sample data from a demo plant.

Live monitoring of many meters

Reads many meters over RS-485, Modbus TCP or a gateway at the same time. Meters on one RS-485 line take turns automatically.

Electricity cost and Demand

Estimates the PEA TOU bill so far and for the whole cycle, tracks 15-minute demand against your target and warns before it is exceeded. Rates are editable.

History and comparison

Pick meters, values and periods, compare meters side by side, see peaks with the time they happened, and export CSV.

Alerts where you already are

Alerts by LINE, Telegram and email when a value goes out of range or a meter goes offline, with a daily energy summary.

Reports on a schedule

Daily and monthly PDF / Excel reports, sent automatically by email, LINE or Telegram.

Solar tracking

Production, self-use, export, baht saved and CO₂ avoided — included in the reports.

EnPI and savings

Energy per unit produced, baseline model and cumulative savings — a practical tool for energy-management programs.

TV display

Rotating full-screen pages for a TV or control room. Screen links are view-only and can be revoked at any time.

Any Modbus meter

Ready-made profiles for common meters, and a web editor to add other models from the manual's register map — with a test read before you save. Virtual meters add or subtract meters (whole plant, department, unmetered load).

Modbus toolkit for engineers

Modbus Studio

Everything a field engineer needs to talk to a Modbus device: find it, read its registers, convert the numbers, log them and forward them to the cloud. Works on a laptop with no internet and no monthly fee.

Modbus Studio dashboard
Live values, trend chart and gauges built from the device profile.
Modbus Studio scan page
Scan a Modbus TCP network or find RTU devices on an RS-485 line.
Modbus Studio register map
Read registers, convert data types, swap byte and word order — and write values.
Modbus Studio device profiles
Tag tables for common meters and sensors, with live values. Make your own and share as JSON.
Modbus Studio data logger
Time-series logging to a local database, with history charts and CSV / Excel export.
Modbus Studio cloud gateway
Forward readings to an MQTT broker, including the ThingsBoard format.

Screenshots show a simulated three-phase meter.

Find the device

Scans a whole Modbus TCP subnet at once, or finds RTU devices on RS-485 with automatic baud rate, parity and slave ID detection.

Register map

Read function codes 01–04, convert 16/32-bit integers and float32, swap byte and word order, and write with 05, 06, 15 and 16.

Live dashboard

KPI cards, a trend chart and gauges, built automatically from the tags of the chosen device profile.

Device profiles

Save a device's tag table once and reuse it. Import and export JSON, and use the built-in library of meter and sensor profiles.

Data logger

Logs time series to a local SQLite file with automatic clean-up, and exports CSV or Excel.

MQTT cloud gateway

Forwards readings to any MQTT broker, with TLS, per-tag topics and a ThingsBoard payload format.

Simulation mode

Try the whole program with a built-in virtual meter — no hardware needed.

Offline and bilingual

Thai or English, light or dark theme. License keys are checked offline — no cloud account and no monthly fee.

Before You Ask

Frequently Asked Questions

Do I need the internet or a cloud account?
JETNIPAT Energy runs on your own PC or server and keeps the data in a local file; you open it from a browser on your network. Modbus Studio works fully offline. Sending data to a cloud (MQTT) is optional.
What hardware do I need to connect my meters?
Meters with an RS-485 port need a USB-to-RS-485 adapter or an RS-485-to-Ethernet gateway; Modbus TCP devices connect over the LAN. See our RS-485 wiring guide and Modbus gateway comparison.
Will it work with my meter?
Both programs work with devices that speak Modbus. Ready-made profiles are included for common meters and sensors, and other models can be added from the register map in the manual, with a test read before saving. Send us your model and we will confirm.
Can I try it before I buy?
Yes. JETNIPAT Energy gives a 30-day trial with all features, and the Lite edition of Modbus Studio is free.
Can you install and set it up for us?
Yes. Our engineers can fit the meters, wire the RS-485 bus, install a data logger and set up the software as part of our Energy Management System service.
