:description: Instructions for setting up Xiaomi Mi Home (Mijia) bluetooth-based sensors in ESPHome.

:keywords: Xiaomi, Mi Home, Mijia, BLE, Bluetooth, HHCCJCY01, GCLS002, HHCCPOT002, LYWSDCGQ, LYWSD02, CGG1, LYWSD03MMC, CGD1, JQJCY01YM, MUE4094RT, WX08ZM
The ``xiaomi_ble`` sensor platform lets you track the output of Xiaomi Bluetooth Low Energy devices using the :doc:`/components/esp32_ble_tracker`. This component will track, for example, the temperature, humidity, moisture, conductivity, illuminance, formaldehyde, mosquito tablet and battery level of the device every time the sensor sends out a BLE broadcast. Contrary to other implementations, ``xiaomi_ble`` listense passively to advertisement packets and does not pair with the device. Hence ESPHome has no impact on battery life.

Setting Up Devices
------------------
Required:
- **mac_address** (MAC Address): The MAC address of the device.
- **bindkey** (string, 32 characters, case insensitive): The key to decrypt the BLE advertisements for encrypted sensor types
Optional with **name**, **id** (:ref:`config-id`) and all other options from :ref:`Sensor <config-sensor>`:
- **temperature**
- **humidity**
- **moisture**
- **illuminance**
- **conductivity**
- **tablet**
- **formaldehyde**
- **battery_level**
To find the MAC Address so that ESPHome can identify the device, you can create a simple configuration without any sensor entries:
.. code-block:: yaml
esp32_ble_tracker:
After uploading, the ESP32 will immediately try to scan for BLE devices. When it detects a new sensor, it will automatically parse the BLE message print a message like this one:
.. code::
Found device A4:C1:38:4E:16:78 RSSI=-78
Address Type: PUBLIC
Name: 'LYWSD03MMC'
It can sometimes take some time for the first BLE broadcast to be received. Once the device has been found, copy the address ``A4:C1:38:4E:16:78`` into a new platform entry like shown in the example configurations.
.. _obtaining_the_bindkey:
Obtaining The Bindkey
---------------------
To set up an encrypted device such as the LYWSD03MMC or CGD1, you first need to obain the bind key. The ``xiaomi_ble`` sensor component is not able to automatically generate a bind key, so you need to use the original Mi Home app to add the sensor once (there are `efforts <https://github.com/danielkucera/mi-standardauth>`__ to generate a bindkey without the need for packet sniffing, but it's not working correctly yet). While adding the device, a new key is generated and uploaded into the Xiaomi cloud and to the device itself. Currently a chinese server needs to be selected as the rest of the world doesn't support most of these devices yet. Once generated, the key will not change again until the device is removed and re-added in the Xiaomi app.
In order to obtain the bind key, a SSL packet sniffer needs to be setup on either an Android phone or the iPhone. A good choice for Android is the `Remote PCAP <https://play.google.com/store/apps/details?id=com.egorovandreyrm.pcapremote&hl=en>`__ in combination with `Wireshark <https://www.wireshark.org/>`__. A tutorial on how to setup the Remote PCAP packet sniffer can be found `here <https://egorovandreyrm.com/pcap-remote-tutorial/>`__. Instructions how to obtain the key using an iPhone are `here <https://github.com/custom-components/sensor.mitemp_bt/blob/master/faq.md#my-sensors-ble-advertisements-are-encrypted-how-can-i-get-the-key>`__. Once the traffic between the Mi Home app and the Xiaomi has been recorded, the bind key will show in clear text:
.. code-block:: yaml
packet: POST /app/device/bltbind
"data" = "{"did":"blt.3.129q4nasgeg00","token":"20c665a7ff82a5bfb5eefc36","props":[{"type":"prop","key":"bind_key","value":"cfc7cc892f4e32f7a733086cf3443cb0"}, {"type":"prop","key":"smac","value":"A4:C1:38:8C:34:B7"}]}"
The ``bind_key`` is the 32 digits "value" item in the above output which needs to be inserted into the config file.
