Reading 1-10v wall dimmer with an Arduino

I would like to use the existing wall dimmers in my house to control an led strip light, but the dimmers only have two wires coming from them.

At first my idea was to make a voltage divider to split the 1-10v into 0.5-5v, but I just don't really know what to wire the two wires to.

The dimmers i have are these:

Does anyone know how to use read the value from those dimmers?

Many thanks in advance, David Koster

These dimmers are connected to the house mains supply. They have four connecting wires.

Connecting them to an Arduino would require that all components be contained in insulated housings to prevent contact with any and all wiring, including the LED strips themselves. This sounds an unwise project in general.

Yes, there are four, but the two main wires are only connected to the switch in the dimmer, they do not do anything else.

The only thing I want is to do is read the position from the dimmer with an atmega328,since it's a '1-10v' dimmer I don't think i'd need to insulate everything. I just don't really know what the wires are supposed to connect to and how they're supposed to be read.

Inevitableavoidance: Yes, there are four, but the two main wires are only connected to the switch in the dimmer, they do not do anything else.

I would not be too sure about that!

Looking at the datasheet, I have to suspect that the two wires connected to the mains circuit supply power to the rest of the device, presumably by shunting part of the current whilst turned on.

How else could the device generate 0 to 10V?

Well, I am, i opened one up.

That's the problem, i have no idea.
