Jeg har tidligere hatt driver til denne, men ikke nå. Noen som vet?
Maybe a driver in this channel will do the trick? https://callaway.smartthings.com/channels/c8590ba0-f045-4be7-a0ef-0a238ad6d211
The link you shared is the one that you will use AFTER you have subscribed to the channel. Someone who is not yet subscribe to the channel will get an error 403 if they try to use that link. 
If you want to share a channel link, you need to use the URL that has either “invite“ or “bestow“ in it. That will be the invitation link from the first place where you found out about the channel.
Perfect, thank you🙂
