What is this Ecowitt Entity?

Trying to understand and setup usage of the entities of Ecowitt Integration and don’t know what this one is supposed to represent.

It’s for the soil moisture probes. It ends in “ad”.
I attached screen shots of the entity IDs and entity. The entities ending in pro_soil_ad_#. What are they? It had appeared as default they were disabled but enabling them gave me no more a clue what they represent.


Thanks,
Ed

It is the unscaled value.
Try reading this…:
start [Wiki - Fine Offset Ecowitt Ambient Weather Stations (and clones)] (meshka.eu)

there is a section about the WH51.

Ready to help if I can.
