Zigbee, ZHA, dimmer for 600VA halogen light using transformer

Hi, Have a lot of build in halogen spots in the bath room. A lot, like 36 of them, each 10W.

The system today is using a 600VA old manual dimmer, controlled by a 220v switch. The dimmer is connected to 3 transformers, each of 120VA, called “120/1-KT”.

Have been looking for Zigbee dimmers able to control a old transformer type with a power of at least 360VA. I can actually do with 3 of a smaller type.

Anyone knowing a good model that will work using ZHA with a Conbee II
