I have bought a Düwi Z-Wave shutter switch (05436).
But when I add it to ips it says it’s a Z-Wave dimmer
Does anyone have this device and can you please tell me what I must do to enable this as a shutter switch in ips??

The düwi shutter acts as a dimmer. Dim the instance and the blinds move to the desired position :).
Actually, I’m using the shutter switch as two separate on/off switches.
Can you tell me how to do that with the instance? Could you perhaps provide me with a script example?
That behavior is not supported by the düwi firmware.
Then unfortunately I have bought two of them and can throw them in the trash bin right away :mad:
What is it what you are trying to achieve?
I’m using the shutter switch as two separate on/off switches.
Two (different) things:
I have an airco which can be controlled through two inputs. The inputs are potential-free (or dry) contacts. I want to be able to control those two inputs using Z-Wave. My intention was to use the contacts of the shutter switch because they are potential free. I can’t seem to find any other Z-Wave product which has potential free outputs.
I want to control my mechanical ventilation. It can be switched in low, med, high fan position. I wanted to use the shutter switch to control the med/high fan state. There aren’t much (if any?) other Z-Wave device around which have multiple output switches.
It has been 1,5-2 years since I first looked at Z-Wave, but it seems more and more that there still isn’t much variety in available hardware
I might be wrong with regards to adress your requirement, but using zw_dimset (id, int) you can make the device either power up the up or down terminal.
Knowing that 100% = 100% open (and 0% is closed) and also knowing your current value (e.g. 30%) you can power up the „down channel“ by issuing the command to dim 0%.
As far as I know the device however will latest after 2mins siwtch off all its terminals until the next command will be recieved.
Does this make sense?
Logically speaking I can find nothing wrong in your line of thoughts
It doesn’t however seem to behave in that manner.
When I dim to 0% switch 2 is always ‚made/connected‘. When I then dim to 100% switch ‚1‘ is briefly connected and then instantly the neutral position is achieved.
So I cán switch one of them but the other position behaves not logically
Fortunately for me, I thought of another way which actually dóés work:
Before I want to use the switch I do the following:
-ZW_SwitchMode(52515 /[Z-Wave Dimmer (NodeID 007)]/, true);
-ZW_SwitchMode(52515 /[Z-Wave Dimmer (NodeID 007)]/, true);
-ZW_SwitchMode(52515 /[Z-Wave Dimmer (NodeID 007)]/, false);
After this I know for certain that the switch will always be in neutral position.
I can then execute either
-ZW_SwitchMode(52515 /[Z-Wave Dimmer (NodeID 007)]/, true);
or
-ZW_SwitchMode(52515 /[Z-Wave Dimmer (NodeID 007)]/, false);
to switch either contact 1 or contact 2.
So luckily I now can use the shutter switch as a dual switch with potential free contacts
I’m writing this down here in case other people come accross the same problem and can read my solution. Not in the least elegant, but working nonetheless.
Update: I have installed the switches for the ventilation and the airco and everything is operating nicely.
For the ventilation I have a Düwi switch which turns the ventilation on/off. And a shutter switch for the fan speed.
Switch neutral --> low speed
Switch False --> medium speed
Switch True --> high speed.
For the airco I also have a Düwi shutter switch.
Switch neutral --> Airco off
Switch False --> Airco in Heating mode
Switch True --> Airco in Cooling mode
I am quite happy that the shutter switch can indeed be used as two separate potential free contacts. Mutual exclusive of course, but that’s not a problem in this case.
Thanks for documenting. I also put a link into the german language z-wave forum linking back to this thread.
