Configuring Power Measurement on ANTELA Smart Plug CB2S with BL0942 IC

Another ANTELA Smart Plug
Flashing works fine. I soldered RX TX GND 3.3V to a serial usb adapter. I reset the device by touching the EN pad with a wire connected to ground.
This is what the flasher tool tells me:
these things all work so far.

Device configuration, as extracted from Tuya:
- WiFi LED on P8
- Button (channel 1) on P26
- Relay (channel 1) on P24
Device seems to be using CB2S module, which is using BK7231N.
And the Tuya section starts, as usual, at 2023424

How do I get the power measurement BL0942 ic work? I don't know how to find the correct pins for the ic.
It seems to be different than other antela plugs. The reset pad is named EN instead of RES.

You just need to add "startdriver bl0942" to startup command or autoexec.bat

>>21409630 Thank you. Works fine now.

Why does the openbeken firmware don't send the frequency of the BL0942?
