I use Touch-MI Probe by hotends.fr
Is it possible to set a check that the probe is deploy ?

If the probe is not unlocked at G28, the HotBed hits the nozzle.

Configuration Z-probe:

#define TOUCH_MI_PROBE
#if ENABLED(TOUCH_MI_PROBE)
  #define TOUCH_MI_RETRACT_Z 1.0                  // Height at which the probe retracts
  #define TOUCH_MI_DEPLOY_XPOS (X_MAX_BED + 2)    // For a magnet on the right side of the bed
  //#define TOUCH_MI_MANUAL_DEPLOY                // For manual deploy (LCD menu)
#endif

according to this from their website;
==============
Before any manipulation, for your safety and that of your printer you must imperatively carry out a test of state of the sensor.

With the command 'M119' we can know if the sensor is working properly.

'PIN down' , the command must return a status OPEN

'PIN up' , the command must return a state TRIGGERED

If the state of the sensor is reversed, it will be necessary to modify the logic (true or false) of the endstop Z in the file configuration.h (Firmware Marlin)

#define Z_MIN_ENDSTOP_INVERTING false // set to true to the logic of the endstop.
#define Z_MIN_PROBE_ENDSTOP_INVERTING false // set to true to invert the logic of the probe.
============

if the probe is not deployed, it is in the triggered state.
If everything is properly configured, a Z home will think it is already home and do nothing.
So, what is not properly configured?

Very sorry.

Everything is alright

I had faulty Touch MI electronics.
The above problem occurs when the HIGH level is permanently at the Z-probe output.
