Unfortunately, SmartThings doesn’t provide a designation of how many speeds a fan supports as an attribute. Most SmartThings fan devices we’ve come across support the speeds 0-3, so that’s what the Fan Speed tile was designed around.
| Speed | Description |
|---|---|
| 0 | Off |
| 1 | Low |
| 2 | Medium |
| 3 | High |
This is one of the first SmartThings fan devices we’ve come across that supports a 4th speed (though it does seem to be a nice option!), so I’ve posted over in the SmartThings community and shared the post in the SmartThings developer Slack, but haven’t seen much feedback on it yet.
