I have the same issues as @Olaf_Nekeman as well. ‘Network error’ from the SmartThings app. Http 200 through code, yet program isn’t started.
I’d say this is a SmartThings issue, not a Bosh issue. I also doesn’t work from the https://my.smartthings.com/advanced/devices page. Click on your dishwasher here and if you scroll down, you can test out all the commands and indeed the setStartstop doesn’t do anything … .
I contacted samsung and bosh support. And now we wait … .
