Not sure if you managed to get your Ring Floodlights going, but I just got mine working today. I'm brand new to Hubitat and after trying to figure out Home Assistant, I stumbled across this amazing community.
I just setup my Hubitat and one item on my list was the Ring Floodlight. I came across this post: Ring Floodlight Groovy Code
Using the groovy code from the article I was able to install it as a custom driver in hubitat. I setup a virtual device using the IP for my floodlight and to my surprise the groovy code ported without edit. I added my ring username, password, and device ID and am able to turn the floods on / off from Hubitat.
Warning - getting the Device ID from ring was a little tricky and the directions were not clear (at least for me as a noob). To do it, download an application called "Postman" which will let you call the RIng API. Make sure to setup a new environment in postman to define the global variables the postman script in the article needs. This will give you the device ID for your floods and whatever other ring devices you have on your account.
