I received an Automation & Irrigation hat for Christmas. I have an 8-relay board that I've connected. During the test (Settings tab, Acutator Test) - all of the relays perform the test except Relay1_8. There is a quick blue blip on the counter, then it turns yellow for a fraction of a second and back to zero.

On the Hardware Settings tab, it's configured for GPIO 20. I've made no changes to the hardware settings after using the v11 dropdown preset HW Config.

The only other item I have connected to the Hat is a BME280 sensor, which is working OK.

Is there something I can do to get relay #8 working? Or to test further?

Thanks.
