can't see my fake Xiaomi temp sensor

Hi team,

I planned to develop my own BLE sensor, giving temperature and humidity, based on a nRF52 chip. I make my own sensor, just for fun.

I managed to deal with service datas, and get a advertising very similar to the one given in https://github.com/custom-components/ble_monitor/blob/master/protocol.md

> HCI Event: LE Meta Event (0x3e) plen 37                   #31 [hci0] 2.914649
      LE Advertising Report (0x02)
        Num reports: 1
        Event type: Connectable undirected - ADV_IND (0x00)
        Address type: Random (0x01)
        Address: FA:BE:32:DD:0D:36 (Static)
        Data length: 25
        Flags: 0x06
          LE General Discoverable Mode
          BR/EDR Not Supported
        Service Data (UUID 0xfe95): 5020aa0105360ddd32befa0d1004b2007502
        RSSI: -46 dBm (0xd2)

The only difference I can notice is the address type.

I installed ble_monitor through HACS, on a Home installation, in a python virtual env on a ubuntu server.

Here is the HA logs output:

The sensor is present (FA:BE:32:DD:0D:36), but not data appears in HA.

I probably missed something, but where?

Thanks for your job and support. Vincent

Yes, for sure. Right now, I’m working on a private git repo, but later, I will publish it on a framagit or github.
