Wall switch with Wemos D1 mini

[sunilammanabrolu]

Hi Xose,

I am a big fan of your work and use espurna to control Wemos D1 mini boards in my home connected to few lights and plugs.

I am trying to make the Wemos D1 mini work with a single channel relay connected to D1 pin and a wall switch connected between D3 and GND.

This is my hardware.h

#elif defined(WEMOS_D1_MINI_RELAYSHIELD)

// Info
#define MANUFACTURER        "WEMOS"
#define DEVICE              "D1_MINI_RELAYSHIELD"

// 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_SWITCH | BUTTON_SET_PULLUP
#define BUTTON1_RELAY       1

// Relays
#define RELAY1_PIN          5
#define RELAY1_TYPE         RELAY_TYPE_NORMAL

// LEDs
#define LED1_PIN            2
#define LED1_PIN_INVERSE    1

// When Wemos relay shield is connected GPIO5 (D1) is used for relay,
// so I2C must be remapped to other pins
#define I2C_SDA_PIN         12  // D6
#define I2C_SCL_PIN         14  // D5

The problem now is if the wall switch is in ON position and the board is reset, it never boots up. I have to change the switch to off position to boot it up again

I see this weird line in serial monitor with switch in on position and the board reset

Also if the switch is in off position and the deice is reset, this same line repeats 3 times before the normal boot up

Complete log with switch in off position

I do not know what I am doing wrong. Please help me with this. I hope I have made my problem clear

If GPIO 0 is shorted to GND during boot up, the device will go into program mode, to fix this attach your switch to a different GPIO pin, by default this function was meant for a momentary switch such as a button.
Don't forget to set the new GPIO Pin in your hardware.h file.

Thanks. I used D1 and D2 and it works great. Thank you
If I want to use a 4 channel relay with 4 wall switches, which pins can I use?

This issue can be closed anyway. Thnaks for the support

Can you share you code? How you control led strip with espurna using wemos d1 mini? Or its not about led strip? What you mean when you say lights?
