CoRE - Get peer assistance here with setting up Pistons

Hi all,
I’m a self confessed noob, but have created a couple of pistons that work pretty great for my needs!
One area I’m struggling with are with Lightwave RF devices (light switches).

I can control them from within the smartthings app using @adamclark_dev’s integration found here:

However, in Core pistons, the switches are completely unresponsive.

Can anyone instruct me on how best to diagnose this please?
I did a search, but came up with nothing, so apologies if I missed the answer.

Thanks!
