This note describes what the IoT Bridge Plugin sends and to where. It is not a separate agreement: the Plugin is covered by the ChromaChecker End-User License Agreement (the "EULA"). It is published because the Plugin talks to a message broker that you choose, which may be on another machine.
1. What this Plugin does
IoT Bridge connects WiFi and Zigbee sensors — temperature and humidity sensors, signal towers — to CC Capture through an MQTT broker. Readings arrive as messages and become environment values inside the application.
2. Where it connects
| Protocol | MQTT (the paho-mqtt client) |
| Broker | whatever host and port you configure |
| Default | localhost:1883 — a broker on the same workstation |
| Zigbee | a USB coordinator on a serial port, when one is used |
The default keeps everything on the workstation. Any other setting does not. If you point the Plugin at a broker on another machine, sensor readings, topic names and the workstation's client identifier travel to that broker over your network, and whoever administers it can read them. If you point it at a broker outside your premises, they leave your premises.
The connection uses the credentials and transport security your broker requires. ChromaChecker does not operate a broker for you and does not receive these messages.
3. What is stored
The broker address, port and your connection settings are stored in the workstation's application settings. Measurements taken from sensor readings are stored with the job they belong to, the same as any other measurement.
4. No third-party processors
ChromaChecker introduces no third party here. The broker is yours, or your supplier's, and its terms are between you and them.
