EFUN SH330W Plug
Model reference: FCC S7JSH330
Configuration (old version)
Tuya-Convert might not be possible for this device since the template was added (2020-09-09). 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.
Bought about a dozen of these in 2018/19, and all of them were flashable with Tuya-Convert.
