Smart Plug HS110 Consumption Characteristics are always 0
I have added a HS110 to my network.
It is used to control my TV. In TP-Link's own app, it is shown to be drawing around 45w (current power).

However, inside Eve, its consumption level is always 0 (and it is saying that the outlet is not even in use)...
