Tuya-Convert might not be possible for this device since the template was added (2020-10-06). All new Tuya devices have firmware preventing flash but it is still possible to Tuya-Convert old stock devices without connecting them to the Tuya app.
The text on the back reads:
Type 120 Wi-Fi Smart Socket Model: Oittm WS01 Rated Current: 15A-20A(Max) Rated Voltage: AC110-125V/50-60Hz Rated Power: 2000W Wireless Frequency: 2.4GHz Wireless Standard: IEEE802.11 b/g/n
There is a blue LED that is independently controlled, a red LED that goes on and off with the relay, the relay/switch controlling power to the outlet, a momentary button, and an HLW8012 IC that can retrieve RMS voltage, current, power (watts), power factor, and more. The IC was determined by opening the device and inspecting the PCB. The PCB also had ““KS606 WIFI 2017/3/21”” or ““KS606 power 2017-3-22 Ver 1.1”” silkscreened on it in a few places.
Through manual template creation, I found that this ESP has an identical pinout and behavior to the Sonoff POW V1. I found this relation via the shared usage of the HLW8012 power monitoring IC
