NorthQ Watt Calculator for two NorthQ Power Meters

Hello, I recently bought my second NorthQ Power Meter for calulating the total heating wattage. To see the wattage of my first Power Meter (whole house) I use the app NorthQ Watt Calculator. But that, it seems, can only handle one Power Meter.

Does anyone have a suggestion how to see the wattage from my second Power Meter?

best regards

I have the same issue, did you find any solution for two meters?
