C320WS (V1.6)

Key dates

Release

May 2022 · estimate

How I calculated it: Month of TP-Link's own US press release (dated 2022-05-16) on the launch of the Tapo C320WS in the US. The release names the model, not a hardware version; V1 is the earliest hardware version on TP-Link's US download page for this model, and TP-Link states Vx.0 = Vx.6/Vx.8. TP-Link does not state an exact on-sale date; the release date is used as the launch month.
