Virtual Temperature Sensor still has math error when calculating differential temperature in Fahrenheit (F).
For example, a differntial temperature of 1 C does not equal a differntial temperature of 33.7 F.

Internally the device works with Celsius. The difference can not be simply calculated correctly by the aquaero because of a necessary formula (°C = (°F - 32) * 5/9) and further calculations.
That will not change in the future since it is way to complicated too integrate this in a useful manner.
