Control Roborock S7 -> how to only vacuum (not mob)


I have a Roborock S7 MaxV Ultra, and I really loved to control it over OpenHab. Sadly I’m only able to use it with activated mob feature (means vacuum plus water cleaning). Although, I set the parameter


to 200 as described here, it selects a mode where a the mop is used (what I do not want).

Tested with:

// Set mob mode to "Off"
events.sendCommand("Roborock_S7_Water_Box_Mode", "200");
// Vacuum kitchen

Does somebody have an idea how to solve this problem?
Thanks in advance!
