As for oucher, you’d probably have to write your own program or script depending on how Dreame’s bump works. For Roborock it watches a logfile for bumper events, so I wouldn’t be surprised if you can find something similar in Dreame or even something like /dev/sensor1 that you can poll.
Only works for Roborock, right? Would love that for my bot, but it’s a Dreame.
