Hi all, I searched through the forum for quite some time today and learned quite a lot. But I seem to be unable to find an answer to my problem. I have a Homey Bridge and a Qubino 3-Phase smart meter. In flows I can define variables, i can assign values to variables by e.g. timestamp. However, I just cant manage to calculate the difference of two variables and assign it to a third one. TotalConsumption = DayEnd - DayStart.  
Am I missing something or as calculation not supported in the “standard” flows?

Kind Regards,  
Kay
