Hello @johnjoe_30 , will you please post your question in this thread? SwitchBot gets an open API! - #17 by tomw
Specifically, what are you running in to with the last step? The link instructs on how to find the required info. The "newly created Device" refers to the Hubitat device page.
Anyway, if you reply in the thread that I linked to you will be able to get help from the rest of the users and keep the discussion in one place.
