* Shine on, you, crazy diamond !
Strange, but in Sonoff Basic red led does not show relay status, as on TH10/TH16. But there is a pin labeled LED on connector for external RF module. And it lights up red led.
After fixing electrodragon SPDT double relay board it is time to add some addition functionality.
Board has 4 leds – power, eps status, 2 relay status but when cover is on – they are hidden.
So i decide to make it visible.
