KMC 70011 Support

[WayneManion]

I bought three KMC 70011 energy-monitoring smart switches from Amazon for less than $30.

I chose these because one of the reviews said there was an ESP8266 inside and that it works with Tasmota. I prefer Espurna, so I did some research and found out the 70011 uses the same power monitoring circuit as the Sonoff Pow. I dug through the Tasmota source and found the pin configuration inside the 70011. I added the following bit of code to hardware.ino:

#elif defined(KMC_70011)

    // Info
    #define MANUFACTURER        "KMC"
    #define DEVICE              "70011"

    // Buttons
    #define BUTTON1_PIN         0
    #define BUTTON1_MODE        BUTTON_PUSHBUTTON | BUTTON_DEFAULT_HIGH
    #define BUTTON1_RELAY       1

    // Relays
    #define RELAY1_PIN          14
    #define RELAY1_TYPE         RELAY_TYPE_NORMAL

    // LEDs
    #define LED1_PIN            13
    #define LED1_PIN_INVERSE    0

    // HLW8012
    #ifndef HLW8012_SUPPORT
    #define HLW8012_SUPPORT     1
    #endif
    #define HLW8012_SEL_PIN     12
    #define HLW8012_CF1_PIN     5
    #define HLW8012_CF_PIN      4

The device appears to work, power monitoring and all. I'm not terribly familiar with using Git, so I put the code here instead.

I should add that flashing these devices is pretty simple. There is some kind of ESP-12 module soldered to a larger PCB. Just connect 3.3V and GND to a power supply of some kind and Tx and Rx to a serial adapter and off you go. The button is connected to GPIO0, so pressing it when you turn the device on puts it into programming mode.

Thank you! Added it to the dev branch. Will be released with 1.12.4 soon.

This is staged for release.

I just bought 3 of these from Amazon as well. I backed them up, erase the flash, flashed the pre-built kmc firmware and nothing. I took a (1MB) backup and tried to flash it back and nothing. Tried to flash a second device and nothing when I plug it in or when it reboots after flashing connected to the ttl interface. Curiously, my plugs say KT-70011B-KMC V1.0 instead of the 1.2 that's in the wiki. Not sure where to start debugging. There's no serial output when running serial monitor in Arduino at any baud rate. I tried to flash both 1.13.5 and 1.13.5 and no joy. Do you recall what release of the board you received?

Hi mr. Manion, I saw in the amazon comments/review that you managed to flash the Xenon Touch switches. I have one of this (a 2 gang) can you send a wiring which to buttons do I have to push in while connecting to USB to bring it in flash mode? Many thanks in advance. Any help would be appreciated
