Fair point, and we’ll look into some easier ways to update a single attribute tag through the Device: Update Node.
Here’s another way that you may find easier to use: The bulk device update API endpoint supports adding, editing, or removing attribute tags one at a time. So instead of using the Device: Update Node, you could use the Losant API Node targeting the Devices: Patch resource/action. Demonstration workflow is attached.
The downside is that the bulk edit operation does not include the updated device(s) in the response, hence the Device: Get Node following the Losant API Nodes so that you can get the device with the updates applied.
