Lamps plugged into outlets controlled by smart switch-- need wiring advice

If I understand your question, you can do it if you change the wall switch so that it is no longer a load control switch and doesn’t control the outlets at all. All it will do is send a message to the smartthings hub which will then send a message to the bulbs.

A popular switch for this purpose is the go control/Linear WT00z accessory switch which is not intended to control a load. Although it says it will work only was zwave bulbs, since you are using SmartThings, it will also work with zig be bulbs or hue bulbs connected to the hue bridge because the switch passes message to the hub and the hub passes the message to the bulb. :sunglasses:
