Local tuya problem with creating sensor that measures w

Hello ned help
I have install LocalTuya and have no problem with creating swithes (on and off) for my smart plugs this works fine.
When I check attribut for my switches it show correct values. When I then create a sensor for any of this switches I creted it will not show consumerized watt!
It shows 0W and Attribut Raw state 0.

Anyone that can help?
