Hi all

Can anyone help with stopping mains voltage triggering notification being sent via pin D6? Every time I hit the downstairs light switch the wemos thinks its a trigger. is it interference or the power supply to the Wemos?

Try a 1000uF and .01uf cap across the 5v or 3.3v power supplied to the Wemos
