Today I purchased a Yun Rev2. Initially all looked like it was working perfectly, however, after the heat relay(solid state) turns off, it does not turn back on when the status turns to heat again,
So the auto button is green, and the power button yellow. If I then click the power button to make it green, the heater will turn on, but then it doesn't turn off.
I've tried all the PWM ports.
Also tried different ports for the temp ds18b20
I'd really appreciate any hints.
