The Wifi Smart Socket EU (SPL-W-TY-PM-EU-RY-L) by Sky-Lighting has been available under various brand names since around August 2022, for example at Action DE, Amazon.de and Calex. There is a variant with 10A at a maximum of 2500W and another with 16A at a maximum of 3680W, which are usually integrated into the smart home using the Alpina Smart, Calex Smart, Hema Smart, LSC Smart Connect or Smart Life app.

Principle of operation
The plug type is E+F and the socket type is F, while energy measurement is performed using a BL097. The connection to the Tuya cloud is carried out using the CB2S radio-frequency module by Tuya, which has a BK7231N microcontroller by Beken.
Firmware flashing
It is not possible to disconnect from the Tuya cloud using CloudCutter, as the pre-installed firmware version 1.1.17 with class oem_bk7231n_plug has already been patched against the known vulnerability.
Therefore, OpenBeken must be flashed via the serial interface (GND, 3V3, TX1, RX1). Here you will find instructions and pictures on how to open the case as well as flash the firmware.

Firmware difficulties
Am I correct in understanding that the calibration depends on the model, or does it have to be done individually for each device? If someone has determined generally applicable values, would they be willing to share them?
