It is recommended to use a Hue Bridge when connecting Hue bulbs to Hubitat Elevation for optimal results. Even though Hue bulbs use a Zigbee connection and can talk directly to your hub, they may interfere with the routing of the Zigbee network traffic when connected directly to Hubitat Elevation without a bridge. Once connected through the Hue Bridge Integration app, your bulbs can be used just as if they were directly paired with your hub.
While Hubitat Elevation can control your Hue Bulbs and Hue Groups, it is not possible to create Hue Groups or Hue Scenes from the Hue Bridge Integration, so your first step is to configure your Hue Bridge and Hue bulbs from your Hue mobile app.
From the sidebar of your hub, select Apps and press the Add Built-In App button.
Choose the Hue Bridge Integration from the list of built-in apps
Select Done to continue with the Hue Bridge Integration setup
Discovery of your Hue Bridge(s) will begin.
Select your Hue Bridge from the drop-down menu.
You must now authorize communication on the local network with your Hue Bridge. This requires that you physically press the round button on top of your Hue Bridge. Once that is complete, return to the hub and press Done to continue to Hue Bulb Discovery.
Hue Bulb Discovery will find new and existing bulbs on your Hue Bridge. Select Refresh Bulb Discovery if your new bulbs are not automatically discovered.
Add your Hue Bulbs from the list by checking the box next to the bulb name. Select Done when finished.
Your Hubitat Elevation Hue Bridge Integration supports Hue Groups. It's recommended to use Hue Groups with your Hue bulbs to avoid a so-called "popcorn effect" where lights that should operate in unison, instead do so in a seemingly random order. This effect is completely eliminated by the use of Hue Groups.
Select Find Groups from the Hue Integration app to begin the discovery of Hue Groups.
Select from the available list of Hue Groups. If you are a HomeKit user, there will be additional groups that start with the letters hgrp. Ignore these groups as they are internal to the HomeKit integration with your Hue Bridge. Select only Hue Groups you created in the Hue app.
Select Done when finished. Your Hue Groups will now show in your Hubitat Elevation Devices list and may be used in Rule Machine automations, controlled from your Hubitat Dashboard, etc.
