Slow response between Z-wave controller and wifi light bulbs

Hi, I have Home Pro (old version) and Wiz smart lightbulbs which connect to the router, and then to Homey Pro. If I use Wiz’s own remote they respond quickly. I bouth a z-wave 8-button controller (Namron), which is compatible with Homey, and it works, but it takes 2-3 seconds for the lights to respond.
Is there anything I could do to improve this?
Thanks :slight_smile:

Hi again, anyone who could help with some suggestions?
