Indeed, the idea of a decoder, converter and validator is that you can separate decoding binary data (i.e. bytes to voltage), converting units (voltage to temperature) and validating measurements (remove outliers).
We’re dropping the converter and validator in V3 as they’re not being used; you can put conversion in the decoder, and it makes more sense to drop/filter out invalid values higher upstream.
The requested feature is really being able to transform binary data to another binary format, right? You don’t really want to manually convert your binary payload to CayenneLPP in JavaScript right, just to update the Cayenne dashboard?
What is the goal? Let’s see if we can find a sensible solution that leads to that!
