Hi there, I have qubino roller shutters in all my house and I want to set the position to 0,25 or 0,5 %. I have found out, that the app just allows me to set parameter to whole percents. So just 0%, 1%, 2%, … 99%, 100% 0% is closed and 100% is opened. I set parameter to 0,01 to express 1%. That works. When I go lower to 0,005, this does not work. To explain further. There is a lot of wind in my area and the blinds just do not handle so much wind and make noise. If I open it just by little, it is better. But if I open it 1%, it opens so much the light from streetlight shines to my eyes. So I have to adjust it manualy and it really is not feasible to do every day. Thank you for your tips and help.

That isn’t possible and is a device limitation (or rather a Z-Wave limitation), the Z-Wave command used goes from 0 - 99 (0x00 - 0x63) where 0 = closed and 99 = opened, there are no decimals possible (or in z-wave terms “precision”) for this Z-Wave command class. ---

Thank you. Nevertheless, I am pretty upset. I spent thousands of euros on smart home and it does not do such simple task for me ☹ ---

Well, (I think) You will have a hard time to find _any_ electronic roller shutter that supports decimals in their percentage control (high precision) as the amount of people needing this kind of precision is pretty much negligible. ---

Also, it seems you’re blaming your home automation system for something that sounds like an issue with your blinds. ---

No problem with the blinds. Problem is with the technology and it cannot open to desired position. I can open it manually to that position, but that is why I installed smart home in the first place. ---
