Philips Hue
Philips Hue support is integrated into Home Assistant as a Hub that can drive the light platform. The preferred way to setup the Philips Hue platform is by enabling the discovery component.
Once discovered, if you have a custom default view, locate configurator.philips_hue
in the entities list ( < > ) and add it to a group in configuration.yaml
. Restart Home Assistant so that the configurator is visible in the Home Assistant dashboard. Once Home Assistant is restarted, locate and click on configurator.philips_hue
to bring up the initiation dialog. This will prompt you to press the Hue button to register the Hue hub in Home Assistant. Once complete, the configurator entity isn’t needed anymore and can be removed from any visible group in configuration.yaml
.
When you configure the Hue bridge from Home Assistant, it writes a token to a file in your Home Assistant configuration directory. That token authenticates the communication with the Hue bridge. This token uses the Address of the Hue Bridge. If the IP address for the Hue Bridge changes, you will need to register the Hue Bridge with Home Assistant again. To avoid this you may set up DHCP registration for your Hue Bridge, so that it always has the same IP address.
Once registration is complete you should see the Hue lights listed as “light” entities; if you don’t you may have to restart Home Assistant once more. Add these light entities to configuration.yaml and restart Home Assistant once more to complete the installation.
If you want to enable the component without relying on the discovery component, add the following lines to your configuration.yaml
file:
# Example configuration.yaml entry
hue:
bridges:
- host: DEVICE_IP_ADDRESS
Configuration variables:
- host (Optional): IP address of the device, eg. 192.168.1.10. Required if not using the
discovery
component to discover Hue bridges. - allow_unreachable (Optional): (true/false) This will allow unreachable bulbs to report their state correctly.
- filename (Optional): Make this unique if specifying multiple Hue hubs.
- allow_in_emulated_hue (Optional): (true/false) Enable this to block all Hue entities from being added to the
emulated_hue
component. - allow_hue_groups (Optional): (true/false) Enable this to stop Home Assistant from importing the groups defined on the Hue bridge.
Migrating from older configuration
In previous versions of the Hue component the configuration looked different:
# Example configuration.yaml entry
light:
- platform: hue
host: DEVICE_IP_ADDRESS
You will need to convert each bridge into an entry in the new configuration style. See above for an example.
Multiple Hue bridges
Multiple Hue bridges work transparently with discovery, you don’t have to do anything. If you prefer to configure them manually and use multiple Hue bridges then it’s needed that you provide a configuration file for every bridge. The bridges can’t share a single configuration file.
Add filename
to your Hue configuration entry in your configuration.yaml
file:
# Example configuration.yaml entry
hue:
bridges:
- host: BRIDGE1_IP_ADDRESS
filename: phue.conf
- host: BRIDGE2_IP_ADDRESS
filename: phue2.conf
Using Hue Groups in Home Assistant
The Hue API allows you to group lights. Home Assistant also supports grouping of entities natively, but sometimes it can be useful to use Hue Groups to group light bulbs. By doing so, Home Assistant only needs to send one API call to change the state of all the bulbs in those groups instead of one call for every light in the group. This causes all the bulbs to change state simultaneously.
These Hue Groups can be a Luminaire
, Lightsource
, LightGroup
or Room
. The Luminaire
and Lightsource
can’t be created manually since the Hue bridge manages these automatically based on the discovered bulbs. The Room
and LightGroup
can be created manually through the API, or the mobile app. A bulb can only exist in one Room
, but can exist in multiple LightGroup
. The LightGroup
can be useful to link certain bulbs together since.
The 2nd generation Hue app only allows to create a Room
. You need to use the first generation app or the API to create a LightGroup
.
Example:
To create a LightGroup
named Ceiling lights
that contains the lights 1, 2 and 3, execute the following command:
$ curl -XPOST -d '{"name": "Ceiling lights", "lights": ["1", "2", "3"]}' http://<bridge>/api/<username>/groups
The <username>
is the string that is used to register Home Assistant on the bridge, you can find it in the phue.conf
file in your configuration path. <bridge>
is the IP address or hostname of your Hue bridge.
You can find out the ids of your lights by executing the following command:
$ curl http://<bridge>/api/<username>/lights
Home Assistant will automatically detect your new LightGroup
and add it to the interface.
To support Hue Light Groups, your bridge needs to have at least firmware 1.13 (released on June 3, 2016).
More information can be found on the Philips Hue API documentation website.
Using Hue Scenes in Home Assistant
The Hue platform has its own concept of scenes for setting the colors of a group of lights at once. Hue Scenes are very cheap, get created by all kinds of apps (as it is the only way to have 2 or more lights change at the same time), and are rarely deleted. A typical Hue hub might have hundreds of scenes stored in them, many that you’ve never used, almost all very poorly named.
To avoid user interface overload we don’t expose scenes directly. Instead there is a hue.hue_activate_scene service which can be used by automation
or script
components.
This will have all the bulbs transitioned at once, instead of one at a time using standard scenes in Home Assistant.
For instance:
script:
porch_on:
sequence:
- service: hue.hue_activate_scene
data:
group_name: "Porch"
scene_name: "Porch Orange"
Service data attribute | Optional | Description |
---|---|---|
group_name |
no | The group/room name of the lights. Find this in the Hue official app. |
scene_name |
no | The name of the scene. Find this in the Hue official app. |
Note: group_name
is not linked to Home Assistant group name.
Finding Group and Scene Names
How do you find these names?
The easiest way to do this is only use the scenes from the 2nd generation Hue app. That is organized by room (group) and scene Name. Use the values of room name and scene name that you see in the app. You can test these work on the dev-service
console of your Home Assistant instance.
Alternatively, you can dump all rooms and scene names using this gist. This does not tell you which groups and scenes work together but it’s sufficient to get values that you can test in the dev-service
console.
Caveats
The Hue API doesn’t activate scenes directly, only on a Hue Group (typically rooms, especially if using the 2nd gen app). But Hue Scenes don’t actually reference their group. So heuristic matching is used.
Neither group names or scene names are guaranteed unique in Hue. If you are getting non deterministic behavior, adjust your Hue scenes via the App to be more identifying.
The Hue hub has limited spaces for scenes, and will delete scenes if new ones get created that would overflow that space. The API docs say this is based on “Least Recently Used”.
