A simple API to control Philips Hue lamps with http GET requests.
The existing Philips Hue REST API requires a PUT request to control the Hue lights and groups.
I needed GET, so I made a simple API to translate from GET to PUT. It also supports the standard GET command so you can use hueget for both.
hueget suports controlling lights as well as groups. A group is a collection of a number of lights, which in the Philips Hue app appears as a room.
This is my first ever API javascript program, so if you see any way it can be improved, I'd be happy to receive your suggestions.
If you like this tool, consider buying me a coffee!
Flash your lights in the entire house when the doorbell rings. I have a Shelly1 as my doorbell. The doorbell connects to the Shelly1 SW input using a relay on the doorbell buzzer. Thus when the doorbell button is pressed, the Shelly1 sees an input, and calls a url, which flashes a group of lights for 15 seconds using the alert=lselect command. I use the Philips Hue app to determine what lights should be in the group.
Anything that can call a url when triggered - such as a Shelly Motion Sensor - can be used to turn the lights on and off again. Make sure the motion sensor calls a url to turn lights on, and a url to turn lights off. The Shelly Motion Sensor is ideal for this, as you can activate call urls for different motion triggers.
Toggle a light or group of lights from a button that sends a non-changing URL. The toggle command is perfect for any pushbutton controller that does not know (or can not know) the current light state, and only sends a non-changing static URL, such as a Shelly Button 1.
Flash lights in a room or in any group (zone, room) when someone comes home. The alert=lselect command is perfect to generate a 15 second long flash without any extra programming. Just call the URL from Apple HomeKit automations when a person arrives in your geofence.
I run hueget on my raspberry pi. To install the latest version with NPM:
$ npm install hueget
Or for the latest beta version:
$ npm install hueget@beta
You need to know where hueget was installed. Use find -name hueget.js to find the location of hueget.
I prefer to install locally. In my case, on my Raspberry Pi and using the default user pi, hueget installs in /home/pi/node_modules/hueget/
To update hueget to the latest version:
$ npm update hueget
The following examples assume you have hueget in a folder that your system can find. Update your PATH variables if needed. The following examples use a Philips Hue bridge IP address of 192.168.0.101. Adjust to match the IP address of your Hue bridge.
To see the help text, start hueget without any arguments as follows:
$ node /home/pi/node_modules/hueget/hueget.js
hueget shows the following response:
Missing option: "--ip"
USAGE: node hueget.js [OPTION1] [OPTION2]... arg1 arg2...
The following options are supported:
-i, --ip <ARG1> Philips Hue bridge IP address (required)
-u, --username <ARG1> Philips Hue api username (required)
-p, --port <ARG1> port number to listen on ("3000" by default)
Note that options can be entered in any order.
Example to run hueget on a raspberry pi to connect to a Philips Hue bridge with ip address 192.168.0.101, default port 3000, and with a Hue username of UBxWZChHseyjeFwAkwgbdQ08x9XASWpanZZVg-mj:
$ node /home/pi/node_modules/hueget/hueget.js -i 192.168.0.101 -u UBxWZChHseyjeFwAkwgbdQ08x9XASWpanZZVg-mj
The same again, but using port 1234:
$ node /home/pi/node_modules/hueget/hueget.js -i 192.168.0.101 -u UBxWZChHseyjeFwAkwgbdQ08x9XASWpanZZVg-mj -p 1234
A successful start of hueget (using the above command to specify ip address 192.168.0.100 and port 1234) will show:
hueget v0.7.3
commands will be sent to 192.168.0.101 with username UBxWZChHseyjeFwAkwgbdQ08x9XASWpanZZVg-mj
listening on port 1234
Ideally hueget will run all the time. You need a tool to start hueget when your system restarts. On my raspberry pi, I use pm2 (Process Management Module).
To startup pm2 running so it auto-starts on pi reboot, use this command and follow the instructions from pm2: $ pm2 startup
To start hueget with pm2, and have it daemonized, monitored and kept alive forever:
$ pm2 start /home/pi/node_modules/hueget/hueget.js -- -i 192.168.0.101 -u UBxWZChHseyjeFwAkwgbdQ08x9XASWpanZZVg-mj -p 3000
Check that hueget has started:
$ pm2 status
Save the pm2 config so that hueget automatically loads when the server restarts:
$ pm2 save
Managing hueget in pm2 is straightforward:
$ pm2 status
$ pm2 start /home/pi/node_modules/hueget/hueget.js.js -- -i 192.168.0.101 -u UBxWZChHseyjeFwAkwgbdQ08x9XASWpanZZVg-mj -p 3000
$ pm2 save
$ pm2 stop hueget
$ pm2 restart hueget
$ pm2 delete hueget
$ pm2 describe hueget
For more information about pm2, see https://github.com/Unitech/pm2
If you have Homebridge, and the homebridge-hue plugin, look at the users section of the hue config. You will see the Hue bridge MAC address folowed by the Hue bridge api username
"users": {
"ECB5FAFFFEFFFFFF": "yourPhilipsHueBridgeUsername"
},
The username will look something like this:
UBxWZChHseyjeFwAkwgbdQ08x9XASWpanZZVg-mj

Groups are collections of lights, and are used for Rooms and Zones in the Hue app.
The hueget server supports a special toggle command, which does not exist natively in the Philips Hue bridge. This toggles (changes the state) of a specified light or a group, allowing you to toggle the light/group state with a single URL.
Syntax:
- Toggle light 1: http://192.168.0.101:3000/api/yourPhilipsHueBridgeUsername/lights/1/toggle
- Toggle group 2: http://192.168.0.101:3000/api/yourPhilipsHueBridgeUsername/groups/2/toggle
The API is transparent to all Philips Hue keywords. It expects all name=value pairs to be separated by a comma. If any comma is required inside a value, eg: for the xy command which expects a value array, then you must url encode the comma to %2c.
The full JSON response for a light looks like this:
{"1":{"state":{"on":false,"bri":198,"hue":5360,"sat":192,"effect":"none","xy":[0.5330,0.3870],"ct":500,"alert":"select","colormode":"xy","mode":"homeautomation","reachable":true},"swupdate":{"state":"noupdates","lastinstall":"2021-08-21T01:50:00"},"type":"Extended color light","name":"Standard Lamp","modelid":"LCA001","manufacturername":"Signify Netherlands B.V.","productname":"Hue color lamp","capabilities":{"certified":true,"control":{"mindimlevel":200,"maxlumen":800,"colorgamuttype":"C","colorgamut":[[0.6915,0.3083],[0.1700,0.7000],[0.1532,0.0475]],"ct":{"min":153,"max":500}},"streaming":{"renderer":true,"proxy":true}},"config":{"archetype":"floorshade","function":"mixed","direction":"omnidirectional","startup":{"mode":"safety","configured":true}},"uniqueid":"00:17:88:01:08:ff:ff:ff-0b","swversion":"1.90.1","swconfigid":"35F80D40","productid":"Philips-LCA001-4-A19ECLv6"}}
The full JSON response for a group looks like this:
{"name":"Lounge","lights":["9","1","2"],"sensors":[],"type":"Room","state":{"all_on":false,"any_on":false},"recycle":false,"class":"Lounge","action":{"on":false,"bri":0,"hue":7800,"sat":138,"effect":"none","xy":[0.5302,0.392],"ct":153,"alert":"select","colormode":"xy"}}
The most common action keywords for state or group are: on, bri, hue, sat, effect, xy, ct, alert, colormode, mode (lights only). More keywords exist, see the API documentation.
Turn a light on or off. On=true, Off=false. Valid for light or group. A group also supports all_on and any_on.
The brightness value to set the light to. Brightness is a scale from 1 (the minimum the light is capable of) to 254 (the maximum).
The hue value to set the light to. The hue value is a wrapping value between 0 and 65535. Both 0 and 65535 are red, 25500 is green and 46920 is blue.
Saturation of the light. 254 is the most saturated (colored) and 0 is the least saturated (white).
The xy values represent x and y coordinates of a color in CIE color space. The first value is the x coordinate and the second value is the y coordinate. Both x and y must be between 0 and 1, and will be rounded to 4 decimal places by the Hue bridge, eg: 0.666666 becomes 0.6667. If the specified coordinates are not in the CIE color space, the closest color to the coordinates will be chosen.
When sending the xy array, you must url encode the comma to %2c (or %2C). Here is an example for "xy":[0.25,0.52] :
- Set light 31 to xy of [0.25,0.52]: http://192.168.0.101:3000/api/yourPhilipsHueBridgeUsername/lights/31/state?xy=[0.25%2c0.52]
The Mired (micro reciprocal degree) color temperature of the light. Ranges from 153 (6500K) to 500 (2000K). To calculate the mired, use the formula mired = 1000000/K, where K is the desired color temperature. Example: 6500K = 153 mired, calculation 1000000/6500 = 153.8
The alert effect, this is a temporary change to the bulb’s state, and has one of the following values:
- “none” – The light is not performing an alert effect.
- “select” – The light is performing one breathe cycle.
- “lselect” – The light is performing breathe cycles for 15 seconds or until an "alert": "none" command is received.
Note that this contains the last alert sent to the light and not its current state. i.e. After the breathe cycle has finished the bridge does not reset the alert to “none“.
The dynamic effect of the light. Supported values:
- “none” - No effect
- “colorloop” - Cycles through all hues using the current brightness and saturation settings.
Indicates the color mode in which the light is working, this is the last command type it received. Values are “hs” for Hue and Saturation, “xy” for XY and “ct” for Color Temperature. This parameter is only present when the light supports at least one of the values.
Indicates if a light can be reached by the bridge.
The duration of the transition from the light’s current state to the new state. This is given as a multiple of 100ms and defaults to 4 (400ms).
Increments or decrements the value of the brightness. bri_inc is ignored if the bri attribute is provided. Any ongoing bri transition is stopped. Setting a value of 0 also stops any ongoing transition. The bridge will return the bri value after the increment is performed. Range -254 to 254.
Increments or decrements the value of the sat. sat_inc is ignored if the sat attribute is provided. Any ongoing sat transition is stopped. Setting a value of 0 also stops any ongoing transition. The bridge will return the sat value after the increment is performed. Range -254 to 254.
Increments or decrements the value of the ct. ct_inc is ignored if the ct attribute is provided. Any ongoing color transition is stopped. Setting a value of 0 also stops any ongoing transition. The bridge will return the ct value after the increment is performed. Range -65534 to 65534.
Increments or decrements the value of the xy. xy_inc is ignored if the xy attribute is provided. Any ongoing color transition is stopped. Setting a value of 0 also stops any ongoing transition. Will stop at it’s gamut boundaries. The bridge will return the xy value after the increment is performed. List of xy values. Max value [0.5, 0.5].
Exact use unknown. Looks like it reflects an operating mode. Observed values are: homeautomation
See the API documentation.
For full details of the control capabilities, please see the official Philips Hue API reference. An alternative unoffical reference, somewhat outdated, also exists.
You need to know the light id or the group id of the light or group you wish to control. Go to http://192.168.0.101:3000/api/yourPhilipsHueBridgeUsername/lights respectively http://192.168.0.101:3000/api/yourPhilipsHueBridgeUsername/groups. You will see a JSON responce that looks like this (truncated here for brevity, only lights is shown. Groups is similar):
{"1":{"state":{"on":false,"bri":198,"hue":5360,"sat":192,"effect":"none","xy":[0.5330,0.3870],"ct":500," ...
Copy and paste the response into a text editor and format as JSON (or use an online JSON display tool). Then search for the name of the light (as shown in the Home app) in the text response, here I searched for "Desk lamp":
... ,"type":"Extended color light","name":"Desk lamp","modelid":"LCT012", ...
Go backwards in the text until you find the keyword state, this is at the start of the JSON text for the light. The light id is the number immediately before state. In this case, my light id is 31:
... ,"31":{"state":{"on":true,"bri":100,"hue":65396 ...
Use the same method for groups to find the group id of the room you wish to control. Note that group id 0 is a special group containing all lights in the system, and is not returned by the ‘get all groups’ command. Group 0 is not visible, and cannot be created, modified or deleted using the API, but group 0 can be controlled by the API.
