Thanks a lot for your help.
Now I have created and published the driver and it is listed on the tab “My Device Handlers” as Published. But when I open the handler I am getting the following warning:
DTHs set to run locally, when used with incompatible devices, may cause local rules to not behave as expected. If this occurs, remove the local flags, re-publish the DTH, and re-save the rule.
When I open my SmartThings app and try to add the device, I still can’t find it in IKEA supported devices.
Do I have to do something more or how do I proceed?
