Aqara Wall switch double rocker Power consumption


I’m brand new in home assistant and nearly total newbie on zigbee protocol.

I just installed an Aqara switch double rocker without neutral(WS-EUK02 : lumi.switch.l2aeu1
). It’s associated with A Sonoff Zigbee Dongle 3.0.

I can manage the switch by itself which is the main purpose butall power informations (voltage, consumption etc.) remain at 0 or unknown.

Is there anything to do to get them ?
