The `mitemp_bt` sensor platform allows one to monitor room temperature and humidity. The [Xiaomi Mijia BLE Temperature and Humidity sensor with LCD](https://www.amazon.com/Temperature-Humidity-Xiaomi-Bluetooth-Screen-Remote/dp/B079L6N6PC) is a small Bluetooth Low Energy device that monitors the room temperature and humidity. As only a single BLE device can be polled at the same time, the library employs locking to make sure this is the case.

Depending on the operating system you're running, you have to configure the proper Bluetooth backend on your system:

- On a [generic Docker installation](https://www.home-assistant.io/docs/installation/docker/): Works out of the box with `--net=host` and properly configured Bluetooth on the host.

- On other Linux systems:

- Preferred solution: Install the `bluepy` and `btlewrap` library (via pip). When using a virtual environment, make sure to use install the library in the right one.

   - Fallback solution: Install `btlewrap` library (via pip) and `gatttool` via your package manager. Depending on the distribution, the package name might be: `bluez`, `bluetooth`, `bluez-deprecated`

- Windows and MacOS are currently not supported by the btlewrap library.

Start a scan to determine the MAC addresses of the sensor:

Check for `MJ_HT_V1` or similar entries, those are your sensor.

To use your Mi Temperature and Humidity sensor in your installation, add the following to your `configuration.yaml` file:
