I have a similar setup with some GE smart switches that I installed which are controlling my Hue smart bulbs (like you they are not actually physically controlling anything, they are just wired hot all the time as are the hue bulbs). The GE switches are working fine for me in this scenario. I chose them as I also wanted to control some ceiling fans (in the same gang box) and GoControl does not make a fan switch with z-wave in it. However, their accessory switch does have a z-wave radio in it and it would work in your case. I also went with the GE as the GoControl switches have pigtails attached to them and in some places in my house jamming all those wires and wire nuts back into the box would have been a challenge. The GE wire in from the back. The GE have blue LED’s in them and the GoControl have green, if that matters to you.
However, I am using the Smart Lighting app to control my setup rather than a SmartThings automation. I just created a Toggle effect in Smart Lighting where the switch will turn on all the lights if it gets pressed (by sending the appropriate Z wave command to the ST hub)…and then I made it so that ONE of the lights turning on is the “switch” which will tell the wall switch to turn on. This works really well. Basically 2 different SL effects for each light/switch combo I have setup (currently I have this working in five different rooms).
Here’s my thread I started a while back where I discuss what I did and the choices I made if you care to read through it.
