Exploring Smart Lighting Solutions for Existing Wall Switches

I’m currently exploring options to retrofit smart lighting into my home without replacing the existing wall switches. Most smart bulbs don’t fit my multi-bulb setups, and family members often turn them off, disconnecting them from control. I want to keep wall switches for ease of use but need a smart solution that works with them.

I’ve looked into replacing switches, but many require a neutral wire, which I don’t have. I also need a variety of switches—1 gang, 2 gang, 3 gang, 3-way, and 4-way—plus dimmers. Finding a single manufacturer with this range at a reasonable price has been challenging.

I found a device that seems promising but isn’t compatible with SmartThings. If only they had a ZigBee version! Does anyone know of a smart switch that works with SmartThings and existing wall switches? I’d love to hear your recommendations and experiences!

Thanks for your help!
