Hi, I point out this silly note as it might ease the life of newbies like me.

The Wemos D1 Mini relay is a very handy dev platform to test espurna before flashing on less accessible devices, at least because you don't have to press buttons to flash it and there is a handy hardware reset button.

The D1 doesn't came with an equivalent of the Sonoff button, but it's easy to add it by connecting a pushbutton between GND and D3 (GPIO0), like I did in the attached picture.

In Espurna 1.9.5 you must esplicitely enable it for the Wemos, but leaving it enabled without having connected the button doesn't give problems, so IMO this may be added permanently.

Add in hardware.h inside #elif defined(WEMOS_D1_MINI_RELAYSHIELD)

#!arduino
    // Buttons
    // No buttons on the D1 MINI alone, but defining it without adding a button doen't create problems
    #define BUTTON1_PIN         0   // Connect a pushbutton between D3 and GND,
                                    // it's the same as using a Wemos one button shield
    #define BUTTON1_MODE        BUTTON_PUSHBUTTON | BUTTON_DEFAULT_HIGH
    #define BUTTON1_RELAY       1

Add in hardware.ino inside #elif defined(WEMOS_D1_MINI_RELAYSHIELD)

#!arduino
        setSetting("btnGPIO", 1, 0);
        setSetting("btnRelay", 1, 1);

Cheers.
Piero
