My wonderful PioT relay board has recently developed a fault with one sticking relay. All four relays have operated fine for months, but one of them now intermittently gets stuck "on". When the GPIOs are switched, I see the indicator LEDs switch on and off accordingly, but one of the relays sometimes gets stuck in the "on" state, no longer switching along with the GPIO and indicator LEDs.
When the relay gets stuck on, a sudden shock (hefty tap) to the case containing the board will return the relay to its normal state. It then continues to operate as normal for a while, but then sticks again a few days later.
Is there anything you ModMyPi guys can do please? Looking back, it's 15 months old, and has operated perfectly until recently.
Need some help with your shiny new breakout board, or something not working right? Let us help you here!
