Hello. I have a similar problem. I added the Smartthings skill to Alexa and it only discovered my N950 soundbar. But i cannot manage to add my A/C. I have tried to disable and re-enable the skill. Not working.
Update: Seems to be a problem relatet to this type of device. Altough i can fully control the device from smartthings app, it does not show up in Alexa App.
But i found an answer here.
- login to https://account.smartthings.com
- find your aricon under the devices list
- Click the Edit button on the bottom of the device details page
- Change Type from “Samsung OCF Air Conditioner” to “SAMI Samsung Air Conditioner” and hit Save (don’t worry, you’ll be able to switch it back)
- Now refresh
- Your Aircon from SmartThings will show up and you can assign it to a room. However you won’t be able to control it (all settings are grayed out)
The A/C now shows up in Alexa App but i cannot open the device page. Seems it is not supported yet.
