I have 3x P110M smart plugs. Purchased from Amazon UK 22nd November 2023. Since install none of the smart plugs have reported energy usage history in the Tapo app. They show the Current Power but the Energy Usage never changes from <0.001kWh and Runtime stays at 0h. I have run them for weeks now without any data. I have tried resetting 2 of them by holding the button down for 10 seconds after I read this was a fix in another forum post, but this has not resolved the issue. I have deleted all the energy data on one of the reset units to see if that would kick it into action but that has not resolved it either.

The resolution if the reset does not work seems to be to return these plugs for a replacement but as they're so new I am expecting Amazon just to ship me another 3 of v1.0 and they have the same problem. I'm hoping there is something else to try. 

I notice the firmware (which it says is up to date) states it is 1.1.0 but a TP-Link articule about Energy monitor on P110 says the latest firmware is at least 1.6. These are the Matter plugs (P110M) so I understand the firmware version might be differnt for those but I wanted to point this out.
