So I am developing an app integrating Philips Hue smart lights. I am using Hue SDK in swift 4. I want to show available groups in a Table View just like the bridge, and then allow the selection of a group to apply light state changes to. I cant find any documentation anywhere on groups, so any sample code or resources would be soooo appreciated!

The Philips Hue Swift documentation shines again by its absence

This is how you get all the groups from the selected bridge:

    let groups = bridgeController?.bridge.bridgeState.getBridgeResources(of: .group)

And this is how you send a lightstate to a group, i.e. group '0', which is all lights:

    let lightState: PHSLightState = PHSLightState()
    lightState.on = true
    lightState.brightness = 254

    let group: PHSGroup = bridgeController?.bridge.bridgeState.getBridgeResource(of: PHSDomainType.group, withIdentifier: "0") as! PHSGroup

    group.apply(lightState, allowedConnectionTypes: .local, completionHandler: { (responses, errors, returnCode) in
        // do something
    })

  • Oh my lord! Thank you so very much! Made my weekend! – Matt Foreman Mar 30 '18 at 19:56
  • Back again! Just wondering what the best route is to change the colors of lights within a group. Your code allows me to change the color of the whole group, but I have a script to randomly change the colors every 5 seconds. What would you recommend to change the colors of each light within the group to a random color every 5 seconds? Thanks so much! – Matt Foreman Mar 02 '19 at 18:48
  • At the moment I am not working with the HUE SDK, but probably I would take all the lights from a group, throw them in an array and do the things.. – Matthijs Apr 12 '19 at 11:18
  • Is it possible you could send some pseudocode for that? – Matt Foreman Jul 25 '19 at 17:59
