The Device: Create Node requires using the ID for referencing the recipe. You could look up the recipe ID by providing a name to the Device Recipes: Get endpoint in the Losant API Node but that would require the addition of several new nodes, not to mention adding an awful lot of overhead to each and every request. You’d also have to ensure that no name searches could match multiple recipes (for example, “my great” matching “my great recipe” and “my great device recipe”). I’d recommend biting the bullet and just using the ID.
Alternatively you could maintain a map of recipe names to IDs as an object in globals, but you’d have to update this object every time a recipe was created, deleted, or had a name change. You could then use the {{lookup}} helper to retrieve the ID given a full name match.
