I use a sdm-120 modbus power-meter to monitor a home battery.
Every thing works normal except “Demand Period”.
This is on address Register 40003 , and according the manual should except values 0,5,8,10,15,20,30,60 minutes. Al values work except 0.
I’ve search around and think it might be related to float has a +0 and -0.
Tried to force a +0 or -0 via map transform but that is not working. Any suggestions what to try next.
