In 2022, I developed a Desktop application for controlling LIFX smart light bulbs. In the later part of 2023, I modified the application to control Philips Hue bulbs instead as I stopped using LIFX in favor of Philips Hue. While it has basic controls for power and color, it can also adjust the bulbs on more advanced levels, such as sun position, outdoor brightness, and weather alerts. It utilizes my Tempest personal weather station for controlling bulbs based on outdoor brightness, lightning, or precipitation.
Main Features
- Basic Philips Hue Bulb Control
- Connect via the Philips Hue bridge directly on the LAN or use the Philips Hue Cloud API. Or, use both (prioritizes LAN and falls back to Cloud API).
- View discovered bulbs (ids and label), connection status, and power status
- Change a bulb's color
- Toggle a bulb on or off
- Flash a bulb to identify it
- Fail Safe
- Timed cycle cache so when an attempted bulb adjustment fails (such as flashing for a weather alert), the program will try again when the bulb reports online within a certain amount of time
- Cycles run in a queue and ensure relevant bulbs are not currently running a cycle before one begins. This ensures cycles do not cancel each other out except for high priority ones (like weather alerts) cancelling lower priority ones (like sun brightness changes).
- Statuses
- View how each component is currently controlling bulbs in the app, such as the current sun / cloud cover brightness, Kelvin, and active weather alerts.
- Conflict Resolution
- When bulbs are set to adjust both for cloud cover and sun, they will take whichever component specifies the brighter setting.
- Sun Control
- Control the brightness of specified bulbs according to current sun position at a configured geo coordinate
- Set minimum and maximum brightness levels
- Kelvin / Warm Light Control
- Control the warmth of configured light bulbs according to the current time
- Set minimum and maximum Kelvin degree values
- Set the hour at which bulbs should reach minimum (warmest) Kelvin, and hour at which they should change back to the coolest Kelvin.
- Sun Brightness Control
- Control the brightness of specified bulbs according to current sun brightness read from a Tempest personal weather station
- Set minimum and maximum brightness levels and at which lux values registered by Tempest those brightnesses should be used.
- The app uses a special exponential algorithm for determining brightness so it is better adapted for indoor brightness
- Lightning / Precipitation indications
- Turn on a bulb to a specific color when lightning or precipitation is in the near-term forecast or has been detected by a Tempest personal weather station. And turn the bulbs back to their original color when the lightning / precipitation is gone. Useful for turning a bulb on at night to drown out lightning flashes when sleeping.
- Weather Alerts Control
- Configure certain bulbs to flash for new weather alerts from the National Weather Service. Bulbs can be specified according to an alert severity level: extreme, severe, moderate, or minor.
- Configure certain bulbs to also flash-cycle active weather alerts every 5 minutes to give you a reminder
- Have bulbs turn on and flash every minute when an extreme alert (such as a tornado warning) is in effect
- Alerts have their own colors depending on the alert (and the app gives a chart and will list active alerts)
Technologies Used
- Electron.JS (JavaScript, Node.js, HTML, CSS)
- AdminLTE website template
- electron-store settings saver for electron
- suncalc astronomical data calculator
- luxon, later, and momentJS date/time libraries
- weathered for connecting to the National Weather Service
- node-hue-api for controlling Philips Hue bulbs
- node-fetch-commonjs for general HTTP requests such as to the Tempest weather API
