Changing brightness of light group up/down not working

I am trying to change the brightness of my light group using a Philips Hue Dimmer. I can get it working if I automate each light on it’s own but wanted to streamline a little.

The lights are turning on/off all the same time but I cannot get the dimmer to work. I’ve tried both using a value % and a set value but it doesn’t change the brightness.

I should add that I am trying to control Tuya wifi bulbs with LocalTuya integration so maybe I had sone something wrong in the initial setup of the devices?
