Correct, it seems there is something missing 😉 |

This is WIP and open for discussion. This addresses eclipse-archived#5099 by adding command options as an alternative to a state description. The implementation is naive and straigt forward. Command options will be rendered as push buttons by UIs and send the corresponding command value as a command to the channel. With this proposal, the state of the channel will not be represented in the UI, so ThingHandelers may not even update the state. Signed-off-by: Henning Treu <henning.treu@telekom.de>

This addresses eclipse-archived/smarthome#5099 by adding a command description with command options along with the state description. Command options will give a hint to UIs about the specific commands a channel provides. Command options could be rendered as a drop down and also represent the current state or rendered as push buttons to simply send a command to the ThingHandler. The infrstructure basically copies the StateDescription infrastructure with CommandDescriptionProviders and an `DynamicCommandDescriptionProvider` interface for bindings to hook in and provide dynamic command options.

There have been several discussions previously about channels which primary purpose is to send commands towards a device (i.e. the opposite direction of trigger channels). There are references in #4272 (comment), #3740 (comment), #4942 and probably some more. Also, there are numerous bindings which support this use-case.
While normal state channels so far have been a good fit for such use-cases, the bindings currently do not have any proper means to express the purpose of such channels and what commands/values are possible or expected: Bindings can only define state options, i.e. a mapping between discrete values and their labels in order to give clues to the UIs how they should be rendered. The same clue is missing for commands currently (which is not necessarily identical).
If there would be something like "command options", then UIs could use them to render the corresponding controls, e.g. buttons instead of the plain number or a drop-down.
