    Super, thanks!
    How can set kWh to switch 1 (sw1) and switch 2 (sw2) and all switches (sw1+sw2)?
    What the code in Sonoff Dual R3?
    Can you help me?

    I just noticed that this trick does not work for this sensor, so then just create a template sensor in Home Assistant. Check the article again. I have added it.

    Hi, Just gotten my Dual R3 and flashed wit exactly the same config as above (wifi stuff changed).
    Flashing was fine, however after hard reboot I get a unsuccessful boot loop with:


    No matter if I flash esphome or tasmota32solo1.bin, the result is the same.

    Board version is 1.6 and the esp32 is the D0WD V3, so I do not understand what is the actual issue.

    I thought it may be power related so I also tried a more powerful power supply.

    Still no luck

    Any pointers?
