Cepaos Gateway
A mini-PC on your network reads the equipment over an industrial protocol.
- 1
In Cepaos, go to IoT & Automation → Gateway and tap “Connect gateway”. You get an install command with a one-time token valid for 24 hours. If it expires, you lose it or reinstall the Raspberry Pi, generate a new one from the gateway page.

Prepare a Raspberry Pi 4 (or a mini-PC) with 64-bit Raspberry Pi OS Lite or Ubuntu Server 22.04+, wired to the winery network and with internet access. Paste the command: it installs the agent as a service in about 2 minutes.

Once the gateway shows as online, add the equipment in IoT & Automation → Connected equipment → New equipment and choose the Modbus RTU (RS-485) protocol.
- 4
On the equipment page, fill in the adapter configuration from the manufacturer’s manual (IP, Modbus registers, NodeIds or tags) and, if you will send commands, what each command writes and with which scale. Cepaos validates every field before saving and never invents registers.
- 5
Tap “Read from the equipment now” on the equipment page: the gateway reads every value on the spot and shows what the equipment answered or why it failed. Then open “View live” to follow the readings.
You need a Cepaos account with the administrator role.
Does the Gateway keep working if the internet goes down?
The agent runs inside the winery: it keeps reading the equipment and stores the events until the connection is back.
