Hi,
I have a Somfy Tahoma integration with HA. But I am unable to use the silent(or whisper) close of my cover. In the Tahoma app I do have this option (the feather icon). How do I use the silent mode in HA automation?
Silent run is basically a throttling of the speed. The slower it closes the less noise it makes 
regards
I am currently working on rewriting the TaHoma integration. Could you possibly log an issue here? -> https://github.com/imicknl/ha-tahoma
I am not sure how to support this from within Home Assistant, but maybe we could add a custom service to set the position in a silent way. I have seen multiple covers with the possibility to open / close the cover in a silent way.
