Add cover entities

[cs33lm]

Thanks for your great contribution on this add-on and your support for the community!

I recently moved from node-red-contrib-home-assistant-websocket to using only this companion, as I wrote my own node red message bus for my KNX, Shelly and Zigbee Smarthome utilizing nodered/discovery to create entities. My goal was to use vanilla node red as much as possible, so websocket was the way. Working like a charm for all my binary_sensor, sensors and switches.

Are there any limitations to create cover entities as well as it is not possible (as stated in the README) to create them? Thx

There shouldn't be any limitations.

I have intentions to add all the Home Assistant entity types. It is just a matter of finding the time to do it. The first step is generalizing the payload sent to HA. Right now, only state and attributes exist and should be moved to a dynamic payload property depending on the entity type.

If you want to add an ad hoc version of the cover entity that functions close to the way the switch node does. I wouldn't be opposed to that, just know that its discovery/update format might change a little once the above changes go in.
