position setting not working

[kratas]

Hi,

I currently use this accessory to control the blinds
https://github.com/kotborealis/home-assistant-custom-components-cover-time-based-synced
however, I have now found out from the log that this add-on will probably become non-functional in version 2025.9, see

Detected that custom integration 'cover_time_based_synced' registers an entity service with a non entity service schema which will stop working in HA Core 2025.9

and unfortunately this add-on has been unmaintained and not updated for years now, I tried this one now, because of the ability to detect the status of what position the blind is now drawn, based on the relay switching based on the given time (this is an absolutely great and important feature for me automation), but unfortunately I came across a thing that I couldn't solve in any way.
Capturing down and up work with status signaling 0-100% perfectly, but what doesn't work is the option to set the exact position, any option to set a given position, for example:

action: cover.set_cover_position data: position: 15 target: entity_id: cover.test_my_cover

is not taken into account and is not implemented, it always ignores the set position and continues to extend or retract the blind until the very end, i.e. either 0 or 100%

Please, is this problem somehow solvable and is there a possibility to fix this defect?

Thanks
