Broadlink sp2 show 0 wat

hii all
i am trying to get power consumption from broadlink sp2 switch
i use hassio
i put the broadlink_power.py in my config\custom_components\sensor
also the config is:

  • platform: broadlink_power
    name: tvled
    host: !secret tv_light
    mac: !secret tv_light_mac

but not luck, i can see the sensor but power consumption is 0 wat all the time.

maybe @Danielhiversen you can help?
any one else?
thank you
