replace manual 4 step dimmer with 0-10V Shelly dimmer

[KaiKiste]

Hello,

I have a LED Lamp which is controlled by a manual dimmer (25% steps). I wanted to replace this dimmer with a shelly 0-10V dimmer to integrate it in the homeautomation. The situation is like that: the existing manual dimmer has 3 cables. as far as I could find out one cable is ground and the other 2 cables both have a voltage between 0-10V. together they have the full 10v and according to the dimmer the voltage shifts from one to the other cable. I could find out the dimmer is called a thyristor. 

So I do not know how to replace this dimmer with a device to control this over wifi.
