@dagloom Ok, now we are getting somewhere.
In UIFLow You can't connect the ENVIII sensor to PortB. ENVIII is an I2C device and has a red connector, PortB is for analog devices and has a black connector.
Both ENVIII sensors have to be connected to PortA via the PAhub2 and then you need to make sure in the config that there are set to the individual PaHub ports not the Cores ports.
The you need GUI labels to show the incoming data from the ENVIII sensors.

The 1to3 mini hub is only usable if the I2C devices have different I2C hubs and the PortBHub is only usable for devices with the black "analog" connector.
