I have a Dutch V4.0 version of the HS110 with the latest firmware installed.

I've set it up via the Kasa app and can turn it on and off through that.

When I go to the Energy Usage screen however a "Something went wrong." message is displayed, with all energy readings showing correctly (i think).

Only thing is that 'Current Power' shows only shows:  -.-- .

So i don't know what the current energy is........

I've tried factory resetting the device several times already. Is there anything else I can do? If not, where do I go for a refund/replacement etc?
