Modbus connection problem LG Energy Storage System
#1
Hi, i am facing problems with reaching a LG energy storage system

1. I have no errors in the log but the data is not automatically updated when they change, only when i update the connection setting (persistant or not connection makes no difference)
2. I have two items i need help to map:

HEMS_R_FAULT_MSG
1150 = 32 bits bitmask (for 25 error codes)
1151 = 32 bits bitmask (for 3 error codes)

HEMS_RW_POWER_METER_ACTIVE_POWER
1162+1163 = 4 bytes big-endian (x100) 

i checked the modbus part on the website but i can't find it :-)
