C120 (V1.6)

Key dates

Release

August 2023 · estimate

How I calculated it: The first firmware TP-Link's US download page lists for this hardware version (1.0.3 Build 230713, published 2023-08-07, marked there as the first firmware release) is used as the launch month; the model may have gone on sale shortly before. TP-Link's own US press release on the launch of the Tapo C120, with availability on Amazon, is dated later (2023-11-13).
