The ``xiaomi_lywsdcgq`` sensor platform lets you track the output of Xiaomi LYWSDCGQ Bluetooth Low Energy
|
|
devices using the :doc:`/components/esp32_ble_tracker`. This component will track the
|
|
temperature, humidity and optionally the battery level of the device every time the sensor
|
|
sends out a BLE broadcast. Note that contrary to other implementations, ESPHome can track as many
|
|
LYWSDCGQ devices at once as you want.

- **mac_address** (**Required**, MAC Address): The MAC address of the Xiaomi LYWSDCGQ device.
|
|
- **temperature** (*Optional*): The information for the temperature sensor.
|
|
|
|
- **name** (**Required**, string): The name for the temperature sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **humidity** (*Optional*): The information for the humidity sensor
|
|
|
|
- **name** (**Required**, string): The name for the humidity sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **battery_level** (*Optional*): The information for the battery level sensor
|
|
|
|
- **name** (**Required**, string): The name for the battery level sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.

Setting Up Devices
|
|
------------------
|
|
|
|
To set up Xiaomi LYWSDCGQ devices you first need to find their MAC Address so that ESPHome can
|
|
identify them. So first, create a simple configuration without any ``xiaomi_lywsdcgq`` entries like so:
|
|
|
|
.. code-block:: yaml
|
|
|
|
esp32_ble_tracker:
|
|
|
|
After uploading the ESP32 will immediately try to scan for BLE devices such as the Xiaomi LYWSDCGQ. When
|
|
it detects these sensors, it will automatically parse the BLE message print a message like this one:
|
|
|
|
.. code::
|
|
|
|
Got Xiaomi LYWSDCGQ 7A:80:8E:19:36:BA Got temperature=23.4°C, humidity=65.0%
|
|
|
|
Note that it can sometimes take some time for the first BLE broadcast to be received. You can speed up
|
|
the process by pressing the grey Bluetooth button on the back of the device.
|
|
|
|
Then just copy the address (``7A:80:8E:19:36:BA``) into a new ``sensor.xiaomi_lywsdcgq`` platform entry like
|
|
in the configuration example at the top.
|
|
|
|
.. note::
|
|
|
|
The ESPHome Xiaomi integration listens passively to packets the Xiaomi device sends by itself.
|
|
ESPHome therefore has no impact on the battery life of the device.
