Sync hue lights in multiple locations from a single controller

hue-sync

Sync Philips hue lights in multiple locations across the web. Users open a webpage, link to their philips bridge, and then cede control. The admin page can select single colors or send simple patterns to all clients currently connected.

Overview

Client

• ✅ Has tutorial to pair with bridge (for now, assume 1 bridge on a network)
• ✅ Can find bridge on network without user inputting IP
• ✅ Listens to a websox multiplexer living on AWS for light commands
• ✅ Pushes new light commands (e.g. level, hue, saturation) to all lights on paired bridge
• ✅ Can pause and resume control without disconnecting the app
• ✅ User can control overall/maximum brighness of lights
• ✅ App can push along hue, sat, bri, on/off commands
• Open Q: Should patterns be run locally or treated just like any other command and we just spam them down?
  • Answer: run locally

Controller

• ✅ Can push commands to a websox multiplexer
• ✅ Can select color
  • Either from palette or from a colorwheel
• Can run basic patterns like a rainbow fade, a hue wave, cycle through a palette, etc.
  • ✅ Can build a generic step/fade pattern with up to 6 colors

Dev Stuff

Client

• Ditched the python client. Going full browser.
• cd client/
• yarn install
• yarn start
• Open http://localhost:3000 if yarn doesn't do it for you

Controller

• cd admin/
• yarn install
• yarn start
• Open http://localhost:3001 if yarn doesn't do it for you

Manual Controller

• Send commands manually to the websocket-based "chatroom" running on AWS
• Install wscat via npm install -g wscat
• Connect: wscat -c wss://mmyh4hlyp8.execute-api.us-east-1.amazonaws.com/Prod
• Send messages like: {"message":"sendmessage", "data":"{\"hue\":33333}"}
• Useful for testing new client capabilities before controller development

Emulator

Download a Hue emulator here: https://steveyo.github.io/Hue-Emulator/

Fire it up with

java -jar HueEmulator-v0.8.jar

Throw a sudo infront of that if you want to develop on port 80.

Basic API Development

Find the IP address of the bridge. If you're using the emulator, it's localhost:8000.

To get a username, press the link button on your bridge/emulator then run the following within 30 seconds:

export HUEUSER=`curl http://localhost:8000/api -d '{"devicetype":"my_hue_app#hue sync"}' -X POST | jq -r '.[0].success.username'`

You can also use newdeveloper as a username for quick development with the emulator, but we will need to be able to generate one for the final project.

To check which lights are linked and their status:

curl http://localhost:8000/api/$HUEUSER/lights

To change the state of light 1 (yes, they're 1-indexed and not 0-indexed):

curl http://localhost:8000/api/$HUEUSER/lights/1/state -d '{"on":true, "hue":33333}' -X PUT
