Hello Christophe75, You can enable the cleaning mode for a GPOD (not GP1-GP2-GP4) module when you hold the left or right navigation buttons for 5 seconds. When you see a cleaning icon, all the user buttons are disabled. So no press will be detected. The module will return to normal operation after 1 minute. you are welcome, Vel007 ---

Or you can program a button on a GP1-2-4 to block all the other modules ---
