Migrate Cayenne Projects

Migrating Cayenne projects to Zafron is easy. Zafron is a drop-in replacement for Cayenne. The only thing you need to do is change the MQTT server hostname and the MQTT credentials. Learn More

Getting Started

The quickest way to get started is to use docker-compose. This will start the server and the database. You will need to provide the MQTT credentials in the docker-compose.yml file.

git clone https://github.com/asanchezdelc/zafron
cd zafron
docker-compose up -d

Navigate to `http://localhost:3000``

Build from source

git clone https://github.com/asanchezdelc/zafron
cd zafron
npm install

Run the frontend

npm run start

Run the backend

PORT=8080 node app.js

Test

Use mosquitto_pub or MQTT.fx to test/send data to the broker with the proper credentials.

mosquitto_pub -h localhost -t v1/thingscafe/things/device-d5f5/data/json -m "[{\"channel\":0,\"value\":1,\"type\":\"temp\", \"unit\":\"f\"}]]"
