I get mad with the configuration of my capacitive Z-probe

Hi!
I get mad with the configuration of my capacitive Z-probe.
The probe is connected to E0 switch. It switches the E0 led on the duetwifi as it should. P0 changes to P1000.
On the web interface, in machine status, the Z stop does not change status, but the E0 status does when switching.
And further more I can't invert the E0 status.
What I am doing wrong? Could s.o. please give me a hint on this?
; Endstops
M574 Z2 S0 ; Set active low endstops
M574 E0 S1
M574 X1 Y1 S1 ; Set active high endstops; Z-Probe
M558 P4 I1 Z2 H3 F200 T5000 ; Set Z probe type to switch, the axes for which it is used and the dive height + speeds H5 F120 T6000
G31 P500 X0 Y0 Z2.5 ; Set Z probe trigger value, offset and trigger height
M557 X15:285 Y15:285 S20 ; Define mesh grid -
Which firmware version are you running?

M558
The "Z2" line in your M558 command is obsolete for versions of firmware after 1.19
M574 Z2 S0 is an Z endstop at the high end of the Z axis, active low. Do you have an endstop at the top of your Z axis?

Is this switching the Z endstop at Z max?
Finally your G31 command looks odd to me, I expect you will have the capacitive probe offset by X, Y or both, unless you are using the tip of the nozzle as a capacitive probe?

Don't rely on DWC - we just had the same issue recently.
Use M119 to check the endstop status instead.See https://forum.duet3d.com/topic/5873/switch-z-probe-not-inverting/31 and the rest of that thread as well!

A Z probe is not the same as a Z endstop! If you want to Z home the printer using a Z probe, you need to use different commands in your homing files. See https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z.
