Hi Andy
Sadly the kinetic switch is the only product in our lineup that isn’t compatible with smartthings.
This is due to ST not supporting the Zigbee Green Power standard as part of their platform.
With regards to the dimmer, we’d need to know a little more about how it’s wired, master or slave mode, what load you have connected etc, as this will ultimately affect its ability to pair properly.
Please open a support ticket at:

One of our team can investigate the specifics of your install and get to the bottom of it for you.
Regards
Andy
