LEDVANCE SMART PLUS PLUG EU

LEDVANCE SMART PLUS PLUG EU based on BK7231T chip (WB2S). Can be flashed with esphome kickstart via tuya-cloudcutter. On publish date you need to use ESP-Home beta to build bk72xx targets. voltage_divider and current_resistor are estimated.

sensor:
  # PC191HA includes a BL0937 chip for measuring power consumption
  #     and BL0937 is a variation of hlw8012, but using inverted SEL pin functionality

    model: BL0937 # note that the model must be specified to use special calculation parameters

      number: P26
    cf_pin: # current or voltage (ele_pin: 7)

    update_interval: $update_interval_seconds # How often to measure and report values

    # PC191HA measures and returns Voltage OR Current according to the value of sel_pin,
    #     but it can change the value of sel_pin periodically
    initial_mode: "VOLTAGE" # reports VOLTAGE or CURRENT

    # Adjust according to the actual resistor values on board to calibrate the specific unit
    voltage_divider: "4456" # LOWER VALUE GIVES LOWER VOLTAGE
    current_resistor: "0.00045" # HIGHER VALUE GIVES LOWER WATTAGE
