How to decode 433MHZ Soil Moisture Sensor - arduino

Question

I need to decode Soil moisture sensor using RXB7 and ESP32. I try several library, it can get data but not the correct one. Due to my knowledge on this 433mhz radio, I can't figure out.
Here's the detail I have about this Sensor, which work on RTL_433.
Here's its protocol detail on RTL_433:
https://github.com/merbanan/rtl_433/blob/master/src/devices/rainpoint.c
What I know about it:
It is OOK PCM at 500 µs rate (half-bit rate as it's Manchester)
A Transmission contains three packets with Manchester coded data, note that the pause is a constant pulse, strangely.
**Detail I get on RTL_433_SDR:

I have use this code(it's also manchester) and it can receive data but it's not the right value.
https://github.com/robwlakes/433MHz_Tx_Rx/blob/master/Receiver1.ino
Here's the output:
A9 10101001 FA 11111010 7C 01111100 FC 11111100 1B 00011011 7E 01111110 FD 11111101 1F 00011111 BF 10111111 FE 11111110 95 10010101
**The expected data is(correct one, as per RTL_SDR):
rainpoint_decode: : {96} aa 81 06 03 9f 04 02 20 07 00 4d 15**
Thus, I think it's the config parameters. I have no knowledge on this preamble, discarding bit...
I also try this one. It also can receive but wrong value:

Any suggestion?
Thanks;
