Are there any plans to extend the Fan Speed capability with an attribute (or other approach) to identify what
fanSpeed values are supported for a fan?
From what I’ve seen, most published Fan Speed device handlers implement the speeds 0-3:
As such, our Fan Speed tile in SharpTools.io is designed to cycle through these speeds, but we’ve had a few requests for devices that support other speeds - for example, a Bond powered device that supports a speed
4 = Max. Unfortunately, there doesn’t appear to be a way to identify which speeds a fan device supports from the reported device details.
Expand for notes on ST Schema Profiles
That being said, I noticed that the reference ST Schema profiles for Fans have options for a variety of different speeds. (Oddly, all excluding a 0 value for off in the example speeds)
|c2c-fan-controller-2speed||Switch, Fan Speed[1,2]|
|c2c-fan-controller-3speed||Switch, Fan Speed[1,2,3]|
|c2c-fan-controller-4speed||Switch, Fan Speed[1,2,3,4]|
Reference: SmartThings Schema Device Handler Types
There is prior art in the SmartThings Capabilities that supports this concept. For example, the Thermostat Mode capability includes a
supportedThermostatModes attribute which defines an array of valid
You can find other similar
supportedXXX type of attributes for Dishwasher Operating State, Dryer Operating State, Media Input Source, Oven Operating State, Thermostat Fan Mode and more.
Perhaps an equivalent supportedFanSpeeds attribute could be added so other integrations could better understand what fan speeds are supported.
Also tagging @bond-jacob and @bond-merck to see if they have any thoughts as it seems like something that would be helpful for SmartThings to add as it would make the device handlers for the various Bond products easier to use in other integrations.
