FMB001 event id 253 received but there is no indicator what type or harsh is it?

@Christian,
sorry I never explore the source, what /model/.java should I check?

I have tried to set 1st server to Traccar and 2nd server to Wialon to make sure that the FMB001 config is correct, the result is:

Wialon able to receive io_253 as below, neither Traccar:

io_253=1, prior=1, event_io_id=253, total_io=42, io_239=1, io_240=1, io_80=5, gsm=5, io_21=5, io_200=0, io_69=1, io_1=0, io_113=100, io_263=1, io_30=0, io_31=41, io_33=253, io_35=37, io_37=5, io_38=4, io_759=1, pdop=1.1, io_181=11, hdop=0.8, io_182=8, pwr_ext=12.351, io_66=12351, io_24=6, cell_id=19293, io_205=19293, lac=3520, io_206=3520, pwr_int=4.104, io_67=4104, io_68=0, io_13=7, io_15=1000, io_36=951, io_52=35, io_260=1705, mcc=510, mnc=21, io_241=51021, io_199=0, io_16=63643000, io_12=2269002, io_4=0, io_389=63643, io_390=370, io_11=894447750000, io_258=281054072471516, io_259=281144265670635, io_14=2591315, iccid=8944477500002591315, vin=MHRRW1880NJ202703

compute attribute --> type -> Alarm

Harsh Accel
io253? (io253 == 1? "hardAcceleration" : null) : null

Harsh Braking
io253? (io253 == 2? "hardBraking" : null) : null

Harsh Cornering
io253? (io253 == 3? "hardCornering" : null) : null

Alarm Notification also set to them

what I missed?

This is an FMC130

no luck :(

If you have device model in Device settings, this computed attributes will not working because is already parsed from the server side.
