I've released a small update, v1.9, to the child app as well as an optional (cosmetic-only) update to the parent app. The most notable change in the child app is that I've now added the ability to activate Hue Bridge scenes if you're using my CoCoHue app as a Hue Bridge integration. This is as an alternative to manually specifying bulb/group settings or using Hubitat scenes, both of which are already (and still remain) options in the app. I find activating Hue scenes via the Bridge is much faster than specifying settings through this app (or Hubitat scenes) for each bulb/group.
You can just use CoCoHue for scenes if you want (there's no requirement to integrate bulbs or groups if you don't want to, and you could leave CoCoHue polling disabled in that case). However, there are other benefits to using this, like being able to use a Hue Bridge group in Dimmer Button Controller and having startLevelChange and stopLevelChange available to you, which Hubitat's integration implements only for Bridge bulbs. This makes the "dim/brighten while held" options work for Hue groups, so you can leave individual bulbs out of the equation entirely here with Hue scenes and Hue groups.
Fair warning, I will probably re-write the app sometime soon, and I'm not sure existing instances will be able to be upgraded (I won't break this app, but it might be like Rule Machine where you can see and modify old rules but not create new ones under old versions, and if you're obsessive about having everything the same version, this may bother you). I might implement Hue scenes directly into the app without the need to create a Hubitat device for them (open to suggestions if anyone would find that useful). My main goal would be to revamp the UI or at least the (messy) code that currently creates it. No timeline, just a heads-up. I'm going to re-create as much as I can on this version though, now that I've got all my Hue lights, groups, and (some) scenes set up via CoCoHue.
