DemandFlow Supply FAN (%) stuck at 0

[dirixmjm]

While the "Exhaust FAN (%)" gives a correct value for the fan speed, the "Supply FAN (%)" seems continuously stuck at 0.
I am not sure this is because this value is not reported, or maybe the wrong register is called?

The info comes directly from the itho firmware and is represented on the add-on interface unchanged. This probably means that your device cannot measure it or that there is another reason why the information is not available.
