@cechurat Hi Tomas,

Should HMI designer be opened from the tray monitor or via the HMI design program it self?

I still can't see the REXYGEN extension, or does this version work differently?

Not on a Monarco, but I moved a Pi 5 off the SD card onto an M.2 drive through a HAT for a small data logger and it has been steadier than the SD card ever was. It boots straight from the drive once the boot order is set in raspi-config. The only thing I would watch is the power budget when the HAT stack is also feeding other boards.
