Govee Temperature/Humidity BLE Home Assistant Component
NOTICE Jul, 15,2021:
Govee support has been added to Passive BLE Monitor integration as of version 4.1.0.
For any new users I would strongly suggest using that integration. BLE Monitor has better support Bluetooth support (including Intel NUC), more sensors and sensor discovery so there is no longer a need to list MAC addresses.
Existing users: I will continue to support this component for the foreseeable future but new development will likely only occur for Passive BLE Monitor integration. Sadly, you will not be able to use both components at the same time.
Thank you @Ernst79 for adding the Govee devices. Ultimately, it makes more sense for you, the end users, to have one component that does everything well and to pool development resources to ensure issues can be resolved quickly.
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 H5051 (BLE only)
- Govee H5072
- Govee H5074
- Govee H5075
- Govee H5101
- Govee H5102
- Govee H5177
- Govee H5179 (BLE only)
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_componentsfolder in yourconfig/custom_componentsdirectory. As example, you will get thesensor.pyfile in the following path:/config/custom_components/govee_ble_hci/sensor.py.
NOTE: the following instructions about setting device permissions are an edge case for a very specific set up. (If you do not understand it, do not worry about).
-
If running Home Assistant without root access the Bleson Python library used for accessing bluetooth requires the following permissions applied to the Python 3 binary. If using a virtual environment for HA, this binary will be in the virtual environment path.
NOTE: Replace "path" with the path to the Python3 binary (example: /srv/homeassistant/bin/python3)
sudo setcap cap_net_raw,cap_net_admin+eip $(eval readlink -f path)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 valid (as it still uses the build in
govee_ble_hciintegration), 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 two period may be required. If the period is set to a time greater than two minutes, at least four period may be required).
5. If the entities are still not displaying data, a restart of the host device may be required.
Troubleshooting and help
Any questions or support should be asked on this component's Home Assistant community post.
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, devices 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: KitchenAdditional component 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. |
temp_range_min_celsius |
float | -20.0 |
Set the lower bound of reasonable measurements, in Celsius. Temperature measurements lower than this will be discarded. Warning: temperatures returned by the Govee device that are outside of the specified range may not be accurate. It is not advised to change this value. |
temp_range_max_celsius |
float | 60.0 |
Set the upper bound of reasonable measurements, in Celsius. Temperature measurements higher than this will be discarded. Warning: temperatures returned by the Govee device that are outside of the specified range may not be accurate. It is not advised to change this value. |
