Difference between dual video doorbells E8203, T8203 and S330

I have the Dual video doorbell model T8203 (wired). Bought last November, 2022.
In the Eufy app it shows that same number.
On Eufys website, that model doesn’t exist. Only ones shown are the E8203 (Wired) and E8213 (battery powered) in the “differences between all eufy doorbells” webpage. Even the S330 doesn’t show up. But I assume the S330 are renamed versions of the E series.

Anyone know the difference the T and E versions of the dual video doorbells? And is the S330 the same model?
