opcgw

opcgw is a Chirptack to OPC UA gateway, enabling communication between IoT devices managed by ChirpStack and industrial systems using OPC UA.

It implements an opc ua server, where opc ua clients can connect on, and a Chirptack client, used to poll the Chirptack server.

Introduction

The main goal of the Chirptack to OPC UA gateway is to allow connecting an SCADA to Chirptack, in order to collect metrics and send commands that will be enqueues on the device.

Some SCADA only understand Sparkplug” mqtt specification. On the other hand *Chirptack entities mainly relies on Chirptack generated ids, that are not really user friendly, which might lead to mistakes when configuring systems.

I wanted to control my LoRa watering valves, in my fruit tree orchards, via my SCADA, in order to optimize water use. I also wanted to learn rust. Therefore I decided to develop this gateway with this language.

Status

opcgw has reach a maturity level that allows to use it in production, with certain car. It does not implement all OPC UA features, but it is enough for my needs and it do the job.

Features

• Communication with ChirpStack server via gRPC API
• Implementation of an OPC UA server
• Management of device metrics via configuration file
