Olá eu tenho (3) treis sonff duplo .. todos treis estão com o mesmo problema do "Faisal Juma" só que eles perdem a conecsão com a rede.
Hi, you can fix it if you put a 10Kohm pull up resistor between "button1" pin and VCC. Hope this helps
Perhaps ITEAD con fix this via software setting the GPIO to INPUT_PULLUP
