Background
I have RTS wooden blinds from 247Blinds in the UK, paired with a Somfy TaHoma Smart Hub and for the last year or so have been controlling them through schedules in the tahoma app.
In daily usage, we’ve tended to leave the blinds down, but just roll the louvres between open and closed. As the app doesn’t expose the tilt property, my workaround has been to have the somfy “MyPosition” as fully down, with louvres tilted horizontally, and then use schedules to call “MyPosition” in the morning, and “Close” at sunset.
This has worked fine, and through the tahoma overkiz integration I’ve been able to use HomeAssistant to close the blind, and call: tahoma.set_cover_my_position
to invoke “MyPosition” on demand, keeping the blind down, but louvres open.
Issue
Recently HA has said I can’t use both the built in Overkiz and third party integrations, so I removed the third party integration in favour of the built in kit.
Now I’m struggling to find a way to set the cover tilt position. The integration has all manner of promising looking service calls around cover.open_cover_tilt
and cover.set_cover_tilt_position
but neither of these does anything when I call them. Changing the call to cover.close_cover
results in the targeted blind closing correctly, but I can’t find a way to separate the louvre tilt, or invoke “MyPosition” from the built in integration, so cannot reopen it without raising it fully.
Attempts to workaround
For now, I’m using HA to close on demand, and the TaHoma app to set “MyPosition” each morning, but I’d like to move these blinds back into the control of HA, as that allows me to switch positions based upon occupancy, light levels, weather, room usage, etc.
TL;DR
Does anyone know how to use HA to target the tilt position of a Somfy RTS tilt/lower venetian blind?
