You colud automaticaly get bindkey from Xiaomi Cloud by configuring xiaomi_account property in MIOT platform.

Sample configuration:

external_components:
  - source: github://dentra/esphome-components

sensor:
  - platform: miot_th
    # String (Required), device MAC-address.
    mac_address: "device-mac-address"
    # String, (Optional), device bind key. Will use "xiaomi_account" from "miot" if absent to automaticaly get the bindkey.
    bindkey: "device-bind-key"
    # String, (Optional), the name of sensor.
    name: "$name Temperature"
    # Sensor (Optional), Humidity, %
    humidity:
      name: "$name Humidity"

    battery_level:
      name: "$name Battery Level"
    # Sensor (Optional), Battey Voltage, V
    battery_voltage:
      name: "$name Battery Voltage"

Now signal strength of a BLE device (RSSI) is not a part of this component, but you could easily add it:

sensor:
  - platform: ble_rssi
    mac_address: "device-mac-address"
    name: "$name RSSI"
