Retrieve information (mqtt) ESP ECU APS DS3 patience4711

Hello everyone!
I use an APS DS3 microinverter connected to two 410w panels and for remote reading, I came across this GitHub post https://github.com/patience4711/read-APSystems-YC600-QS1-DS3 and since I love tweaking things, and at the bottom of my drawer I had a wemos left D1 mini and an old CC2531 usb dongle I said to myself go go! no need for the gateway sold by APS!
Everything is ok on the wemos side, I managed to pair my DS3, I put them up on the web page, but as far as the mosquitto settings are concerned on the esp, put aside by @ip, port and username/mdp , I don’t really know how to configure the rest, there are several formats offered and on HA nothing is detected on the MQTT side.
I admit to being a newbie in this area. I searched the internet in FR/ENG but I found nothing…
If anyone has done this before, I’d like some explanation.
sorry for my English
