In numerous cases,it appears that SmartThings provides only partial support of a number of Zwave Command Class (See: https://graph.api.smartthings.com/ide/doc/zwave-utils.html). For example, the listing indicates only V1 and V2 of the Notification class is supported, even though the ZWave Command Class specification is up to Version 6. This is just one of many examples.
I’m wondering - is it correct that SmartThings doesn’t support all the class versions, or is the issue merely that the documentation is outdated? If it is outdated documentation, how do we find out what really is supported in the latest implementations?
