I newly added a Tapo P410m (outdoor plug) to HomeAssistant via TP-Link Integration.
I didn't use the Matter connectivity.
P410m =
"Solar power monitoring – Detects the direction of electricity and is suitable for both balcony power plants and household appliances"
That is exactly why I want to use it.
The Plug is shown in HA.
If energy is consumed it shows positive values like other plugs (for example P110).
But, If my Plug-In Solar starts generating power, the values change to negative ones and in HA it shortly showed them I believe, but now it just shows as"unknown" for "energy (W)"

I can confirm, I just encountered the exact same problem with my Tapo P410M
