Govee Temperature/Humidity BLE Home Assistant Component

A custom component for Home Assistant that listens for the advertisement message broadcast by Govee Bluetooth Thermometer/Hygrometers.

Supported Devices

• Govee H5072
• Govee H5074
• Govee H5075

Installation

1. Install the custom component:

• The easiest way is to install it with HACS. First install HACS if you don't have it yet. After installation, the custom component can be found in the HACS store under integrations.

• Alternatively, you can install it manually. Just copy paste the content of the sensor.goveetemp_bt_hci/custom_components folder in your config/custom_components directory. As example, you will get the sensor.py file in the following path: /config/custom_components/govee_ble_hci/sensor.py.

2. Stop and start Home Assistant:

• Stop and start Home Assistant. Make sure you first stop Home Assistant and then start Home Assistant again. Do this before step 5, as Home Assistant will otherwise complain that your configuration is not ok (as it still uses the build in govee_ble_hci integration), and won't restart when hitting restart in the server management menu.

3. Add the platform to your configuration.yaml file (see below)

4. Restart Home Assistant:

• A second restart may be required to load the configuration. Within a few minutes, the sensors should be added to your home-assistant automatically (at least one period required).

5. If the entities are still not displaying data, a restart of the host device may be required.

Configuration Variables

Specify the sensor platform govee_ble_hci and a list of devices with unique MAC address.

NOTE: device name is optional. If not provided, deivces will be labeled using the MAC address

sensor:
  - platform: govee_ble_hci
    govee_devices:
      - mac: "A4:C1:38:A1:A2:A3"
        name: Bedroom
      - mac: "A4:C1:38:B1:B2:B3"
      - mac: "A4:C1:38:C1:C2:C3"
        name: Kitchen

Additional configuration options

Option	Type	Default Value	Description
rounding	Boolean	True	Enable/disable rounding of the average of all measurements taken within the number seconds specified with 'period'.
decimals	positive integer	2	Number of decimal places to round if rounding is enabled. NOTE: the raw Celsius is rounded and setting decimals: 0 will still result in decimal values returned for Fahrenheit as well as temperatures being off by up to 1 degree F.
period	positive integer	60	The period in seconds during which the sensor readings are collected and transmitted to Home Assistant after averaging. The Govee devices broadcast roughly once per second so this limits amount of mostly duplicate data stored in Home Assistant's database.
log_spikes	Boolean	False	Puts information about each erroneous spike in the Home Assistant log.
use_median	Boolean	False	Use median as sensor output instead of mean (helps with "spiky" sensors). Please note that both the median and the mean values in any case are present as the sensor state attributes.
hci_device	string	hci0	HCI device name used for scanning.
