Need example code (Arduino) to 'set' and 'read' getPowerAlarm(); and setPowerAlarm(uint16_t watts); #42

Hello I can't seem to get the 'getPowerAlarm()' function to output a usable response. Does the returned value (boolean) in this case represent that the power alarm is 'triggered'? Or does it only signify that a value has been added to the 'setPowerAlarm' register? If you could point me in the direction of an example of working code for the 'get and set' Power alarm functions, it would be very much appreciated.

**forgot to mention that I am using a Chinese Arduino nano clone, all other functions work perfectly for my application so the only issue seems to be the configuration of the power alarm.

Thanks in advance. mjd
