| Mercedes charge coupler stop | Works Cloud | charge_coupler_stop service ends charging and releases cableSaved copyWHAT Adds mbapi2020.charge_coupler_stop, which sends the ChargeCouplerStop command.

| Mercedes EQB 250+ | Partly works Cloud | Partly in Home Preclimate switch shows state but does not start or stop | Pre-climate start/stop from Apple Home failed; server returned ProcessingFailedSaved copy… how do I export the debug log and more details from the sensor "car"? A more detailed description on the issue itself: I installed the custom component MercedesMe 2020 and successfully added my EQB 250+. In the HomeKit Bridge I added the entities locks and switches which provide two devices to my Apple Home, the door lock and the preconditioning.
