I'm in the process of a kitchen reno. Using Halo 4" RL460WHZHA69 lights, along with a GLEDOTPO controller for the under cab. lights.
I wanted to create a simple dashboard today that has on/off/dimmers and CT sliders.
Using this from user @adamkempenich I was able to group the lights, then assign the group to the virtual dimmer/child app.
However, when I created a single "All Kitchen Lights" on/off/dimmer, it... for whatever reason... doesn't want to control the on/off/dimmer of the under cab lights, and instead wants to constantly change the CT of the kitchen lights.
Mind you, I'm trying this with only the UC controller and a single kitchen light on at the moment, but I thought it wouldn't matter much.
