Connectivity & protocols

From field protocol to cloud endpoint.

Every vendor has its own idea of an interface. mini-OTG deals with that on site and gives you one secure, configurable route into the platform you already run.

Discuss your integration
Three-layer architecture

A bridge, not another platform.

The gateway ends the local protocol, normalizes the signals you asked for, and delivers them to infrastructure you own.

Equipment scope

Built around what is already installed in Europe.

The manufacturers below are examples of what turns up on site. Treat them as context, not as a compatibility list: we qualify exact models during integration.

Local configuration

Install. Configure. Deliver.

An installer opens the gateway’s local web server, picks the connected equipment, maps the values you want, and enters your endpoint and credentials. No portal of ours in between.

Equipment

Select profile

Model, port, bus address, variables.

Gateway

Set policy

Sampling, mapping, buffering, security.

Cloud

Enter endpoint

A broker, WebSocket or API that you own.

Integration starts with your stack

Bring the equipment list and cloud contract.

We will go through the interfaces, the payload your platform expects, and what has to happen for commands to travel back the other way.
