*cb* stands for *centibar* and is (I believe) a measure of the soil water tension or the level of moisture held in the soil. Davis soil moisture sensors read in centibars. Strictly speaking I guess that fields that contain Ecowitt soil moisture data should be moved from *group_moisture* to *group_percent*, though given there is no real need for inter-unit conversion (à la temperature or speed) and they use the same default format there is not much to be gained. True, the default unit label is different but that can be easily overridden.
