Transformation for Binary (Non-Text) Data?

I’m setting up some custom sensors that will be reporting their readings via MQTT. It would be easiest for my implementation if they sent data as IEEE floats and left it up to the MQTT clients to handle that encoding.

All of OpenHAB’s default transformations seem to want strings, not binary numbers. Is there a transformation that can ingest binary numbers, or will I need to have my sensors output decimal numbers as strings?

I’ve not tried it but if you use a Number Item and no transform (i.e. default) that should work. If not, you will need to use Strings.
