Fix zero reading if ActivePower if not checked before checking Current #18

Open pm73 opened 5 years ago

pm73 commented 5 years ago

I noticed that if I read only "getApparentPower()" and "getVoltage()" there will by always zero returned by "getApparentPower()".
It seems that "_power" is not updated automatically other than by "getActivePower()" (or by functions which run "getActivePower()" like "getCurrent()" "getReactivePower()" or "getPowerFactor()").

This change makes sure that the "_power" value is updated and it fixed issue for me.

How to reproduce issue:
Try to measure "getApparentPower()" without checking other values.
