interface Philips Hue light bulbs from Julia
Functions to control Philips Hue light bulbs from Julia.
Uses JSON, HTTP, and Colors packages.
To access and control the bridge you need to know its IP address, and register and obtain a ‘username’ (a string of hex) which you can use in subsequent sessions.
For the very first run:
using PhilipsHueB = PhilipsHueBridge("192.168.1.2")initialize(B, devicetype="juliascript#user1")
You’ll now have to run to the Hue bridge and hit the button:
julia> initialize(B, devicetype="juliascript#user1")initialize(): Trying to get the IP address of the Philips bridge.initialize(): Found bridge at 192.168.1.2.initialize(): Trying to register juliascript#user1 with the bridge at 192.168.1.2...register(): Quick, you have ten seconds to press the button on the bridge!register(): Successfully registered juliascript#user1 with the bridge at 192.168.1.2register(): username is KbZxj8G5nBDsDYgqOmHicytLC-aTALLSEaJNinitialize(): Registration successfulyour username is KbZxj8G5nBDsDYgqOmHicytLC-aTALLSEaJNtrue
and the ‘username’ should also be stored in a field of B. Remember it!
testlights(B)
B now refers to your bridge, and most of the functions require this as the first argument.
In a subsequent Julia session, or if you already know your ‘username’, you don’t have to do this initialization, and can simply do:
using PhilipsHueB = PhilipsHueBridge("192.168.1.2", "KbZxj8G5nBDsDYgqOmHicytLC-aTALLSEaJN")testlights(B)
since you remembered that ‘username’.
You can now try:
isinitialized(B) # returns true if correctly initializedgetbridgeinfo(B) # returns a dictionary with information about the bridgegetlight(B, 1) # return a dictionary of information about light #1getlights(B) # return a dictionary with info about all lights on the bridgegetlightnumbers(B) # return array of the "logical" light numbers# set the color of light #1:setlight(B, 1, Dict("sat" => 128, "on" => true, "hue" => 20000, "bri" => 200))using Colorssetlight(B, 1, colorant"Pink")# set all the lights to the same settingssetlights(B, Dict("sat" => 128, "on" => true, "hue" => 20000, "bri" => 200))# quickly test lights for say 20 repetitionstestlights(B, 20)# cycle colors for all colored lights with delay 1 repetitions 10randomcolors(B, 1, 10)
To set the parameters of a light, pass a dictionary with one or more key/value pairs to one of the set functions. Typically this dict is something like this:
Dict{Any,Any}("bri" => rand(0:255), "hue" => rand(1:65000), "sat" => rand(1:255))
where “sat” and “bri” values are saturation and brightness from 0 to 255, and “hue” is from 0 to 65280 (?), where 0 is red, yellow is 12750, green is 25500, blue is 46920, etc. If any keys are omitted, that aspect of the light won’t be changed. Keys are strings, values can be numeric and will get converted to strings.
setlight(B, 1, Dict("on" => false))setlight(B, 1, Dict("on" => true, "hue" => 10000))setlights(B, Dict("sat" => 255, "bri" => 255, "hue" => 20000, "on" => true))setlights(B, Dict("sat" => 25, "on" => true))setlights(B, Dict("sat" => "25", "on" => true))
Using the definitions and conversions in Colors.jl, you can do things like this:
using Colorssetlight(B, 1, RGB(1, 0.3, 0.6))setlight(B, 1, colorant"Pink")
Note that light numbers are not necessarily consecutive, or numbered from 1. For example, if you have four lights, their numbers might be [1, 3, 6, 9]. You can use getlightnumbers() to get the numbers of lights connected to the bridge:
getlightnumbers(bridge::PhilipsHueBridge)
which returns eg:
[1, 3, 5, 6]
Get information for a specific light. For example:
getlight(B, 2)
returns (true,25,254,15000) - On, Saturation, Brightness, Hue
Get the bridge’s current registered IP address (which can usually be read from http://meethue.com using get("https://www.meethue.com/api/nupnp")):
getIP()
Get the current bridge configuration:
getbridgeconfig(B)
which returns a dictionary with keys such as “timezone”, “apiversion”, “paddles”, “whitelist”, and so on. You can obtain specific values:
getbridgeinfo(B)["apiversion"]
returns
"1.29.0"
A list of current approved apps and users is stored in the whitelist:
getbridgeinfo(B, "config")["whitelist"]

For example:
getlights(B)
