MQTT Servers#

GbbOptimizer uses multiple MQTT servers to communicate with inverters and integrations. The server assigned to your installation depends on the PlantId prefix.

How to Determine Your Server from PlantId#

The PlantId prefix (first letter) indicates which server your installation uses:

  • PlantId starting with J (e.g. J1234) -> server gbboptimizer10-mqtt.gbbsoft.pl
  • PlantId starting with a digit (e.g. 1234) -> server gbboptimizer-mqtt.gbbsoft.pl

Port and Encryption#

All MQTT servers use:

  • Port: 8883
  • Encryption: TLS/SSL
  • Authentication: PlantId (as username) and PlantToken (as password)
