1.3 UNOnext WiFi connection method (MQTT)
If the owner is unable to set up RS485 cables for UNOcentral and UNOnext due to certain
reasons, UNOcentral can also use the MQTT connection to receive information from UNOnext's
sensors and linked ventilation equipment. The set up requirements are as follows:

Purchase UNOnext WiFi and correctly set WiFi and MQTT parameters.

UNOcentral must be switched to MQTT mode, and the MQTT parameters and UNOnext
information must be correctly set.

Switch Mode: Refer to 2.1.1.1A System Management to switch.
