What I would like to achieve is to create the cover command only a given seconds and set the state of the cover accordingly.
Such as is, orders could be expressed as “closing at 30%” and action would last the corresponding time and the state would assume the position of the cover accordingly.
I am a beginner with yaml and nodered so I have still to find an already made solution or make it !
EDIT 1 : Here a good beginning :
Manage RF433 covers’ exact position with node-red and Home Assistant - Share your Projects! - Home Assistant Community (home-assistant.io)
EDIT 2 : Here a Custom Component that looks great for the purpose !
Custom Component: Cover Time Based - Share your Projects! / Custom Components - Home Assistant Community (home-assistant.io)
I managed to do it with my RFXTRX integration and gave my configuration files there.
