OverviewThe Philips HUE lighting system is very cool Wifi control of your lighting full color lighting etc You simply replace yourregular bulbs with HUE bulbs and gain the an immediate improvement by having switched to LED lighting Open up theHUE app on your smartphone and you can have very precise control of onoff brightness and color (with color bulbs)of individual bulbs

Thats great but is having to dig out your phone is as bad as having to walk to the wall switch other than not have toget out of bed to turn lights onoff And who carries their phone when going for a midnight snack Using an voiceassistant like Amazon Echo (which I use) helps but you still have to proactively do something and you have to bewithin earshot of the device Wouldnt it be nice if the lighting was controlled for you turning on and off automatically Thats what well do in the project

For this project I decided to use boards in the Feather ecosystem Because it was going to need WiFi connectivityinteract with the HUE system I chose the Feather M0 WiFi It also needed to know what time it was (well see whylater) so I chose the DS3231 RTC featherwing To display some status output I added an OLED featherwing I make useof the A and C buttons on the OLED wing to provide a manual override of lighting for testing These can stack up (withthe OLED and sensor wings on top) with the right headers and a FeatherWing Doubler or Tripler I used the tripler inmy build since I had one sitting around unused

To round it out I built a custom feather wing with the sensors I needed and a NeoPixel for a status indicator

Custom Sensor WingThe off the shelf FeatherWings provide the computing power wifi timekeeping and status display (which isnt reallyneeded but is nice while working on the software) Whats missing is inputs to the system Specifically knowing whensomeone is in the room and how lightdark it is in the room I use this combined with the time of day to figure out howto control the lights

For motion sensing I use a basic PIR For light measurement I use a simple CdS photocell in a voltage divider

There are already excellent learning guides on photoresisters and PIRs so I wont redo them here

Notice that Im also using a NeoPixel This Ill use as an at a glance status indicator since the wifi Feather M0 doesnthave a Dotstar Even if it did the Dotstar could easily be covered depending on how the boards are stacked

As usual I started with the lower profile components the NeoPixel breakout and the photocell voltage divider Keep inmind that the photocell has to be clear of the PIR and able to see the ambient light


I replaced the header pins on the PIR with longer ones that would reach past the capacitors and into the holes on theproto wing


The PIR fits neatly between the photoresistor and neopixel


For this one-off unit I did simple point to point wiring largely on the underside of the board

Talking to HUE

Finding your HUE Bridge

Im using the Wifi101 library to handle communication and ArduinoJson library to handle json generation and parsing

Be sure thatyour WiFi modules firmware and SSL certificates are up to date See the Adafruit Feather M0 WiFi withATWINC1500 tutorial for details

To use the HUE restful interface to control lighting you first have to find out what to talk to

It starts by making a secure connection to wwwmeethuecom doing a GET from apinupnp If the result has a 200status the response body is parsed and the internalipaddress member is extracted Thats the IP on the local networkof the HUE bridge device

To access the API on your HUE bridge device youll need a user See the HUE Getting Started guide for details

Light groups

const char fetch_hue_ip() if (clientconnectSSL(wwwmeethuecom 443)) return NULL clientprintln(GET apinupnp HTTP11) clientprintln(Host wwwmeethuecom) clientprintln(Connection close) if (clientprintln()) clientstop() return NULL

char status[32] = 0 clientreadBytesUntil(r status sizeof(status)) if (strcmp(status HTTP11 200 OK) = 0) clientstop() return NULL

char endOfHeaders[] = rnrn if (clientfind(endOfHeaders)) clientstop() return NULL


if (rootsuccess()) return NULL



In addition to managing individual lights HUE allows you group lights The idea behind this is to group lights intorooms to allow you to control all the lights in a room at once from the hue smartphone app

While everything about your local HUE installation is discoverable through the RESTful API Ive simplified things a bitby hardcoding the group id that the device should control In a full installation each module would need to have itsroomgroup id set somehow In my final vision the name of the room the module is located in would be assigned froma central controller Thats beyond the scope of this guide though

The above code is from setup() It gets the IP of the local HUE bridge and then asks for the lights in the room thatsbeen set

Notice that I use the first (ie the 0th) element in the array of light numbers to stash the number of lights for lateriteration

hue_ip = fetch_hue_ip()if (hue_ip == NULL) while (true) light_numbers = lights_for_group(ROOM_ID)if (light_numbers == NULL) while (true)


Controlling lights

Once the list of lights is in hand they can be controlled

uint8_t lights_for_group(const char group_number) if (clientconnect(hue_ip 80)) return NULL


clientprint(Host ) clientprintln(hue_ip) clientprintln(Connection close) if (clientprintln()) clientstop() return NULL




if (groupsuccess()) return NULL



To keep things simple this just fires amp forgets assuming the lights will get set appropriately You can close thefeedback loop to some extent by querying the HUE some time later to verify that the change was made to the lights










Getting the WeatherOk we dont really care about the weather I use DarkSky to fetch the weather data for the day but ignore everythingother than the sunrise and sunset times Using that information along with the time of day from the RTC the systemcan determine if its day or night

boolean fetch_sunrise_sunset(long sunrise long sunset) if (clientconnectSSL(apidarkskynet 443)) return false


clientprint(Host ) clientprintln(apidarkskynet) clientprintln(Connection close) if (clientprintln()) clientstop() return false

char status[32] = 0 clientreadBytesUntil(r status sizeof(status)) if (strcmp(status HTTP11 200 OK) = 0) clientstop() return false

char endOfHeaders[] = rnrn if (clientfind(endOfHeaders)) clientstop() return false


if (rootsuccess()) return false



return true

boolean update_sunrise_sunset()


The Darksky api takes url arguments for the location units as well as data items to exclude In this case I have itexclude as much as possible to minimize the size of the response body

Note that fetch_sunrise_sunset returns times in seconds be relative to the start of the day That then gets converted toDateTime objects for use later

long sunrise_seconds sunset_seconds if (fetch_sunrise_sunset(ampsunrise_seconds ampsunset_seconds)) return false if (sunrise) delete sunrise sunrise = new DateTime(0 0 0 sunrise_seconds 3600 (sunrise_seconds 60) 60 0)


return true


Using Adafruit IOFor fun I decided to log some things to AdafruitIO

motion startendlight level when motion is detectedwhen lights are turned onoff

Feeds are created in the preamble

We make use of those feeds in loop() For example

Setup MQTTdefine AIO_SERVER ioadafruitcomdefine AIO_SERVERPORT 1883const char MQTT_SERVER[] PROGMEM = AIO_SERVERconst char MQTT_USERNAME[] PROGMEM = AIO_USERconst char MQTT_PASSWORD[] PROGMEM = AIO_KEY


if (motion_started) motion_feedpublish((const char)started)) photocell_feedpublish(light_level)) else if (motion_ended) motion_feedpublish((const char)ended))



Keys and suchYou should never ever put keys and other confidential information in code I have all mine in environment variablesand I use a shell script to put them in a header field that gets included If you use this approach just be careful to addthat header file to gitignore

This will result in a file that looks like

Set any env vars needed to build

rm secretshecho define WIFI_PASS $WIFI_PASSWORD gtgt secretshecho define WIFI_SSID $WIFI_SSID gtgt secretshecho define HUE_USER $HUE_USER gtgt secretshecho define DARKSKY_KEY $DARKSKY_KEY gtgt secretshecho define AIO_USER $AIO_USER gtgt secretshecho define AIO_KEY $AIO_KEY gtgt secretshecho gtgt secretsh

define WIFI_PASS define WIFI_SSID define HUE_USER define DARKSKY_KEY define AIO_USER define AIO_KEY


Putting it all together





if (motion_started) motion_feedpublish((const char)started)) photocell_feedpublish(light_level)) pixelsetPixelColor(0 16 0 0) else if (motion_ended) motion_feedpublish((const char)ended)) pixelsetPixelColor(0 0 0 0) pixelshow() displayprintln(buf) if (is_motion) displayprint( ) else displayprint(No) displayprint( Motion Light )


This starts by reading the motion detector and light sensor Then if weve passed midnight we update the sunrise andsunset times for the new day A flag is used to note that theyve been updated so that it will only update once per day(ie the first time the hour is 0 Once the hour passes 0 the flag is reset for the next day

Next motion startend is detected It looks for a change in the state of the PIR To do this it tracks the previouslyobserved state When the new state differs theres a state change

If motion just started or ended it posts to the motion feed on AdafruitIO and changes the color of the NeoPixelappropriately If motion started it also posts the light reading to the light level feed

Relevant information is also displayed on the OLED

The crux of the process is at the end of loop() This is the code that decides if the lights should be turned on or off

Lights are turned on if

the on button is pushed ormotion has started and

its rather dark in the room orits dark outside

Additionally if the current time is between the (for now) hardcoded get up and got to bed times the lights are turnedon at full brightness otherwise (ie you should be asleep but are up for a snack or drink) they turn on at 10brightness

Lights are turned off if

the off button is pushed ormotion has stopped

In any other case the lights are not changed As you can see the trigger for changing the lights is the push of one ofthe control buttons or a change in motion state

displayprint( Motion Light ) displayprintln(light_level) displayprint(is_between(ampnow sunrise sunset) Light Dark) displayprintln( out now) displayprint(You should be ) displayprintln(is_between(ampnow ampwakeup ampbedtime) awake asleep) displaydisplay()

if (digitalRead(BUTTON_A) || (motion_started ampamp (light_level lt 50 || is_between(ampnow sunrise sunset)))) control_feedpublish((const char)on)) update_all_lights(light_numbers true is_between(ampnow ampwakeup ampbedtime) 100 10) if (digitalRead(BUTTON_C) || motion_ended) control_feedpublish((const char)off)) update_all_lights(light_numbers false 0) delay(400)
