Hi Derek,
I’m using some 12V roller blind motors I found on eBay and used them with fabric from some Ikea roller blinds.
The blinds work well as they have adjustable limit switches for fully open and fully closed positions.
The Qubino interface operates the motor perfectly and has learnt the transit time, so intermediate positions are possible.
Initially I was very pleased but as you will have read the ST does not reliably operate the interface even though it appears to have correctly assigned the Z-Wave Metering Dimmer driver. After a few operations the ST just loses control and although I have played around with delay values in the code I cannot improve matters.
