@ markwarren Sorry to get under your skin!
Since your using smart bulbs, a smart switch makes them useless if controlled with a smart switch.
Ask about a specific Switch and I'm sure a member of the forum will respond with some feed back.
We're not all mind readers here, we (or at least I) don't know what brands of smart bulbs you have nor if your using a hub or the brand of it.
We really do need more info about your system.
Maybe the easiest cheapest solution is to remove the switch.
