yes it is kilowatt-hours (kw) the kit is made by efergy. we have added electricity column to the database and the sensor data in (kw) is logged to database every 5 minutes and it is in agreement to what the kit display is showing in (kw). the display shows the consumption (kw) per day , week, month ,year but we can not adjust the tariff for our need and we believe it is hardcoded in the firmware. in order to get the cost per month we need to have the kw consumed during the month but we do not know how to do it within weewx.
