The ``xiaomi_cgg1`` sensor platform lets you track the output of Xiaomi CGG1 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 CGG1 device every time the
|
|
sensor sends out a BLE broadcast. Note that contrary to other implementations, ESPHome can track as
|
|
many CGG1 devices at once as you want.

Configuration variables:
|
|
------------------------
|
|
|
|
- **mac_address** (**Required**, MAC Address): The MAC address of the Xiaomi CGG1 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 CGG1 devices you first need to find their MAC Address so that ESPHome can
|
|
identify them. So first, create a simple configuration without any ``xiaomi_cgg1`` 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
|
|
CGG1. When it detects these sensors, it will automatically parse the BLE message print a
|
|
message like this one:
|
|
|
|
.. code::
|
|
|
|
Got Xiaomi CGG1 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_cgg1`` 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.
