How to remove faulty sensor

I have several faulty fibaro door/window sensors and want to delete them from sensor list in homey.
Problems are, that they need to be activated by pushing the contact twice on the backside in deleting process. But Thats excatly the malfuntioning switch.

I have trashed the faulty fibaro sensors and installed some very good aqara sensors instead, but how to delete the old one now?
Tx in advance.

Start the deletion specification as normal. Now just wait. Homey automatically deletes the sensor after a period of time, even if the Fibaro button is not pressed. Please then check in the developer whether the sensor has actually been completely deleted.

Thanks Undertaker, it worked perfectly.
