    Arlec Grid Connect PC191HA Series 4 (BK7238 / T1-2S-NL)

    Close-up of a circuit board with a push button and a T1-2S-NL module on a white base PCB held in a hand with two black TIANBO relays and electronic components Label of an ARLEC PC191HA smart plug with energy meter, showing specs and compliance marks

    Unsuccessful with CloudCutter.

    Device configuration, as extracted from Tuya:
    - Wi-Fi LED on P8
    - Button (channel 1) on P24
    - Relay (channel 1) on P26
    Device seems to be using T1-2S-NL module, which is using BK7238.
    Device internal platform - T1, equals BK7238.
    And the Tuya section starts at 2052096 (0x1F5000), which is a default T1/XR806 and some T34/BK7231N offset.

    Close-up of a green PCB with an IC and SMD parts, including resistors marked 889.

    Looks like the Series 4 uses a BL0942 for energy measurement.. not identified above?
