In the last days, port number 2 of my brewpi spark 2 is activated every few seconds.
If I activate it, it works correctly, but when it should be without power, every few seconds it is activated for about 1 second.
At first, it is seen that the relay from the top left, turns on giving power to the glycol pump. After changing the relay that is in port 2 for another, it is observed how the relay of the lower left pare starts to turn on every few seconds.
Can I perform any test or maintenance to know if it is a hardware or software problem?
