Tank senora to Venus GX

I'm trying to get the water tank level sensors connected to the Venus GX. But how.... I can't really get any information out.

I have activated the analog tank sensor on the Venus GX.

The level sensor has two connectors and ground. See picture. b15370ea-3fec-4450-9e94-de98d88756f5.jpeg

On the bottom right picture of that document it shows only two connections (on of which seems to be ground).
I would think you should use the G and ⏚to go to the Venus GX.
Did you choose European 0 - 180 Ω ?

I tried that, yes the settings are European.

Do you have a multimeter to check at the terminals of the sender?
You should be able to measure between 0 -180Ω depending upon the position of the float.
Start at the sender end and then fault find back, you should have similar resistance range at the Venus end of the cable. Once we know that the sender is presenting a resistance to the Venus, we can work from there.

Between the two pins, I get 183
But nothing between the ground and a pin.

But if connect the ground from the Venus on the G and tank 1 on
The Venus give me 0,0% in tank level. And a sensor resistance of 0Ω. See picture.

But can it be reversed so it's 0Ω when is full and 183Ω when it is empty?
