tried to integrate it, but still cant find it by HA. or connect by ble scanner below is their protocol.

my data looks like this
| mac: 64:cf:d9:39:c4:0c | YUNMAI-SIGNAL-C | -86 dB | 0.0 s | 29.7 s | 02 01 06 03 02 10 13 03 02 12 58 09 ff 0c c4 39 d9 cf 64 00 00 | s |

The link you gave explains that this sensor needs to read characteristics, which means that it needs a connection. This is not possible in BLE monitor.
But apparently you also found some passive data. Looking at the passive data, 2nd row, 2nd column = mac address 2nd row, 7th column = name (YANMAI-SIGNAL-C) 1st row, 6th column = flags and data.
So, lets look at this last data
02 01 06 03 02 10 13 03 02 12 58 09 ff 0c c4 39 d9 cf 64 00 00
02 01 06 = flag
03 02 10 13 = Incomplete List of 16-bit Service Class UUID
03 02 12 58 = Incomplete List of 16-bit Service Class UUID
09 ff 0c c4 39 d9 cf 64 00 00 = manufacturer specific data.
Looking at the last manufacturer specific data (That is where usually the data is.
09 = length
ff = manufacturer specific data
0c c4 = company id
39 d9 cf 64 00 00 = data
So, let try to see if the data makes sense.
39 in hex is 57 in decimals (weight?) d9 in hex is 219 in decimals cf in hex is 207 in decimals 64 in hex = 100 in decimals (can be battery)
You can try to see if these bytes make sense to you, but I'm afraid you will need a connection to read the data.
oh i see well then.... looks like i need something more talkable than younmai....
39 in hex is 57 in decimals (weight?) (my is about 115kg), maybe physical condition d9 in hex is 219 in decimals cf in hex is 207 in decimals 64 in hex = 100 in decimals (can be battery) (true)
d9 or cf is unknown for me
