There is an ioBroker integration for the Deebot T9, which also allows you to read its position. You can then send the robot to a specific location. Using this, I configured ioBroker to send the robot to the trash can when it was done cleaning.
Additionally, ioBroker provides a data point for “dustbin removed.” When the dustbin was reinserted, I used that trigger to make the robot automatically return to the charging station.
Is it possible to make these data points available in the Home Assistant integration as well?
