HomeKit 1.2 kVA dimmer for powerful LED strips - has anyone used one?

Has anyone come across a Homekit-compatible dimmer with a load capacity of over 600W and preferably 1.2 kVA?

I have two sets of very powerful LED strips, each about 600W, which are said to work seamlessly with dimmers. Unfortunately, all the ones I have found have a maximum of 300W, so I would have to split the whole installation into 4 dimmers with some kind of synchronisation, which already smells of problems. The question is whether it is possible to handle this on one - max two?

You only need one dimmer plus additional RGB amplifiers which you need to power at the point of connection to the tape - you didn't specify which one?

White tape, not RGB.
