Old device is not removed when you change an installed device's slot

If you change the device slot for an installed device and click apply the old device is not removed

Well, this is really by design with the current UI, which works in terms of slots rather than device types.

Slots were intended to be the simplest implementation mechanism behind the scenes, and the UI hides these from the user. The service/UI can determine a unique device by looking at the combination of beer/chamber/function. If adding a new device matches an existing device with the same beer/chamber/function then the existing one is removed.

(On a related note, the service can also check that the same hardware hasn't been multiply assigned. E.g. assigning the same OneWire address temp sensor, or actuator to multiple functions.)
