To enable long-term statistics for this sensor, and allow the use of the Statistics or Statistics graph cards, can you add this property?

state_class=SensorStateClass.MEASUREMENT

(Just realized this problem is present for a bunch of other IKEA environment sensors as well -- currently the statistics card only shows the temperature sensor but not humidity etc).
