COMMUNITY EDITION · FREE

Plant data.
Live in minutes.

Import one VM, create one account, and watch live signals, trends and history in your browser and on the desktop. No licence key. No cloud. Just your data, moving.

Boot the VM.
A line is already running.

Every Community VM ships with a simulated production line, so you see live values, trends and alarms before you wire a single device.

THE PLATFORM

From sensor
to decision.

Most plants stitch together a driver here, a historian there and a dashboard on top. Meelmo is one environment, from the first sample to the last chart.

Bring your signals together

Configure connections, organize tags into acquisition groups and browse symbols on supported drivers.

ACQUISITION

An engineering workspace

Inspect signals and quality, configure acquisition, and organize the views you use to investigate data.

DESKTOP ENGINEERING

Build operator screens

Compose browser-based HMI pages in a visual studio, with reusable widgets and signal bindings.

BROWSER HMI

Keep the context

Record values with quality and timestamps, then review recordings without losing the context of the original samples.

RECORDING & HISTORY

Investigate behaviour

Inspect acquisition timing and quality. Use measurement cursors and statistics to look more closely at recorded signals.

DIAGNOSTICS & ANALYSIS

Make data accessible

Connect applications to live and historical data through the platform’s data-access interfaces.

OPEN DATA ACCESS
SPEAKS YOUR PLANT’S LANGUAGE

Plug into the equipment
you already own.

The Community Edition includes eight drivers. Siemens, Allen-Bradley, Beckhoff and Mitsubishi drivers come with the Standard and Professional editions.

  • Modbus TCP
  • OPC UA
  • MQTT
  • MTConnect
  • IEC 60870-5-104
  • BACnet/IP
  • DNP3
  • Simulator
UP AND RUNNING

Three steps.
No installer wizard.

The VM installs Meelmo by itself on first boot. You answer three questions at the console; it does the rest.

01 / IMPORT

Open the VM

Import the OVA into VMware, or attach the QCOW2 disk to QEMU/KVM. Two vCPUs and 4 GB of memory are enough.

02 / ANSWER

Create your account

Pick a username, a password and your time zone. One account signs in to the machine, the Desktop and the web HMI.

03 / EXPLORE

Watch it move

Open Meelmo from the desktop or from any browser on your network. The simulated line is already streaming and recording.

ARCHITECTURE

Different interfaces.
A shared data foundation.

The acquisition node, desktop engineering client and browser HMI have distinct responsibilities. Recorded history and data access connect them without making the website part of your runtime.

Acquisition managed by the node.
Engineering and operator experiences kept distinct.
Live and recorded data available in context.

Platform responsibilities

Node / AgentOwns acquisition and exposes the control plane.
Desktop engineeringConfiguration, commissioning and data analysis.
Browser HMIOperator pages and visual authoring.
HistorianRecorded samples and historical queries.
Data accessInterfaces for applications and integrations.
DOCUMENTATION

Read before you run it.

The setup guide gets the VM running on VMware, QEMU/KVM or Proxmox. The user manual covers the Desktop, the operator HMI, building screens and automation.

GOOD QUESTIONS

Before you ask.

Is it really free?

Yes. The Community Edition needs no licence and has no time limit. It covers up to 32 tags and one connected client at a time: the scale of a machine, a skid or a test cell. A Standard or Professional licence adds more drivers, more tags and more clients.

What do I need to run it?

VMware Workstation, VMware ESXi, QEMU/KVM or Proxmox on an x86-64 machine with UEFI. The download page offers the VM as an OVA for VMware and a QCOW2 disk for the others. Give the VM two vCPUs and 4 GB of memory, and a bridged network if you want to reach it by name from other PCs.

Can I connect real equipment?

Yes. Point any of the eight included drivers (Modbus TCP, OPC UA, MQTT, MTConnect, IEC 60870-5-104, BACnet/IP, DNP3) at your devices. The simulated line is there so you can explore before you do.

Where does my data go?

Nowhere. Meelmo runs entirely inside your VM; this website is not part of your runtime. The request form below only collects what we need to send you a download link.
