MQTTBROKER

This driver acts as an MQTT broker for Hsyco. It can connect with many clients but can only receive messages without forwarding them.

HSYCO Configuration

Add the MQTTBROKER I/O Server in the I/O Servers section of the Settings and set its parameters:

Authentication

• Username: optional default username for clients
• Password: optional default password for clients

Authentication file

Under the hsyco root directory must be present a file named "mqttbroker.ini" which can contain a series of line, each line represents the credentials of a client and must have the following format:

E.g.

Client123:username=homesensor,password=abc123
