I have this hex code F0C2CA89012A04008C0000000000000000000000 from the device. This hex code shows the value of the water drops.

In my python code

msg = F0C2CA89012A04008C0000000000000000000000
msg_counters = bytes.fromhex(msg)[5:20] 
# output: b'*x04x00x8cx00x00x00x00x00x00x00x00x00x00x00'      
msg_counters_int = int.from_bytes(msg_counters)
# output: 218157641024778742068286256301735936    
bin_string = '{:0120b}'.format(msg_counters_int)
print(bin_string)

this print the value of bits. These bits shows the value of water

001010100000010000000000100011000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

00101 = 5
01000 = 8
00010 = 2

I’m trying to convert the code to PHP and I’m stuck in int.from_bytes from python. I don’t know how to convert the value.
In my PHP code

$a = hex2bin("F0C2CA89012A04008C0000000000000000000000");
$b = substr($a, 5, 20);
// output: b"*x04x00Œx00x00x00x00x00x00x00x00x00x00x00"

I tried to use unpack functionality but it doesn’t show the correct value
