Hi Mikael,
Here is a link to the Shutter DC custom device handler: https://github.com/kjamsek/SmartThings/blob/master/DeviceHandlers/Qubino/FlushShutterDC/FlushShutterDCDeviceHandler.groovy
I have been using it now for a few days with the new module and it does seem to be working OK.
However, I have two issues left to solve.
The first is that as the DH is not a switch or dimmer, the SmartLigting smartapp can no longer have scheduled routines that include the blinds, as it did when the default z-wave dimmer DH was used. I need to find a way of scheduling the blinds.
Second, the new DH is not seen by Alexa as a valid smarthome device, so voice control is also no longer possible as it was when using the default z-wave dimmer DH . I am not certain what the problem is but I am suspicious that Alexa rejects the blinds DH from voice control because the Open and Close commands make it appear to be a smartlock, which I know is not possible to voice control for security reasons.
Anyone have ideas for scheduling blinds and making voice control work?
