Does ESPHome ble_rssi only work for certain devices?

Hi everybody,

I wanted to give presence detection via bluetooth another show and set up an ESP32 with ESPHome. I added for different bluetooth MAC addresses; three of which are Android phones/tablets, one is a Xiaomi Mi Band 4.

The Mi Band 4 reports it’s status reliably, but neither of the Android devices show up at all. I got their BT MAC addresses from settings -> phone info -> state -> bluetooth address, so they are definitely correct. I also double-checked those two of three that I did not copy & paste. They are correct as well.

And even if those two weren’t, the third one was entered via copy & paste and definitely is/was correct from the start.

Is there a reason these devices do not register at all? The bluetooth relevant part of my configuration looks like this

esp32_ble_tracker:

sensor:
  - platform: ble_rssi
    mac_address: '000'
    name: "BT  MiBand"
    icon: "mdi:guy-fawkes-mask"
  - platform: ble_rssi
    mac_address: '111'
    name: "BT  GalaxyS9plus"
    icon: "mdi:cellphone-basic"
  - platform: ble_rssi
    mac_address: '222'
    name: "BT  GalaxyTab"
    icon: "mdi:tablet-android"
  - platform: ble_rssi
    mac_address: '333'
    name: "BT Mi10"
    icon: "mdi:cellphone-sound"
  - platform: xiaomi_hhccjcy01
    mac_address: 'C4:7C:8D:6C:5D:5F'
    temperature:
      name: "Pflanze AZ  Temperatur"
    moisture:
      name: "Pflanze AZ  Feuchtigkeit"
    illuminance:
      name: "Pflanze AZ  Licht"
    conductivity:
      name: "Pflanze AZ  Erde Leitung"
    battery_level:
      name: "Pflanze AZ  Batterie"

The Mi Flora (hhccjcy01) works fine as well. But currently, all android devices and the Mi Band4 are in the same room and only the Mi Band displays -67 DB, all other sensors are unknown.

Can this be fixed or is ble_rssi not supposed to be able to discover android devices? Thank you in advance for your input
