Somfy RTS shutter via rfxtrx status/proportional


I have Somfy RTS shutter set in my HA.
As of today, I can open, close and stop.
I would like to be able to set intermediate position without using “my” position.

i.e. set 30%, 50% or 70% open.

I guess that would be a time based action i.e. 30 seconds for fully open thus 15 seconds for 50% etc…

Did anyone perform this configuration so far ?


Did you try Custom Component: Cover Time Based - Share your Projects! / Custom Components - Home Assistant Community (

Thanks for your reply.
I’m trying but facing other issues like missing commands for open / close / stop as I do have a single object.

Most likely I’m missing some knowledge on HomeAssistant.
cover_time_based is expecting switches to control cover and I do have a cover object.

i.e. I do have only the object “cover.chambre_1_fenetre”.
vs expected
open_switch_entity_id: switch.wall_switch_right
close_switch_entity_id: switch.wall_switch_left
close_switch_entity_id: switch.wall_switch_left

will try to get some help on this customization

looks like I will have to create a script for each action on each cover :frowning:

Too bad that this customization doesn’t support naively cover objets
