Lumens are a standard unit, so they should be able to be compared, but there are a couple things that might complicate things:
- Directionality/shape of the beam (should be similar if the bulb shape is similar...)
- under what conditions you actually get that output; most Hue devices I see specify at 4000K, where they are normally brightest, but other manufacturers may vary
However, as mentioned above, to get smart control of them, you'd need something besides Caséta switches/dimmers (Lutron doesn't really have this use case in mind--they cut power, and even if you re-write, they don't send button events like many modern smart Z-Wave and Zigbee switches and dimmers do). I don't see any way Harmony could help either, but maybe I'm just not thinking imaginatively enough.
A Pico remote would work; I have many around my home doing something similar. So would any button device you can integrate into Hubitat and then program to turn on, off, dim, etc., the Hue bulbs as desired. Likewise with nearly any current smart switch/dimmer, remote/button device, scene controller, etc. that works with Hubitat and generates similar events you could use to automate.
You also don't necessarily need the controls for Hue integrated into Hubitat. I have several Hue control devices (Hue Dimmer, Hue Tap, Lutron Aurora, etc.), and they work fine as-is. (It's actually kind of nice to have in the event you update your hub -- something I've been doing a lot during the current beta -- and step into another room you expect to have motion lighting while it's rebooting!) Despite having written the CoCoHue integration and a way to get these events into Hubitat, I still don't really make use of that feature.
