Installing iRobot Roomba Combo Essential 2?

Anyone managed to install an
iRobot Roomba Combo Essential 2 with the integration? Never had any problems with other models (three of them), but there is no information on how to get it into the pairing mode.

The integration finds it on the correct IP, but the instruction on the next step: “Press and hold the Home button (or both Home and Spot buttons) on iRobot until the device generates a sound (about two seconds), then submit within 30 seconds.” does not work.

Any clues on how to activate pairing mode on this unit?
