Change granularity of Hue dimmer switch button presses

I have managed to pair a Hue bulb and dimmer. I see there isn’t a simple way to connect the two WRT to dimming. I am creating a set of rules to manage it, but am finding that the dim/brighten buttons trigger a 30% jump each time. This seems pretty extreme. Is the granularity of dimmer button set somewhere in a config file?

Have you added these devices via the Philips Hue add-on or the Zigbee add-on? Either way, please open an issue in the relevant repository:

Thank you. I’ll do that. I’m using the Zigbee adapter with a Conbee 2.
