I’m trying to control several low voltage (5V) AC signals with the Grove 8 channel SSR relay and the relay stays open even though I’ve indicated them to close. The relay channels also stay open even when there is not power connected to the relay. I’ve ran the the sample code and the LEDs on the relay light up as expected. I’m controlling the relay with a Seeeduino V4.2 which is powered by clean 5V source. What am I doing wrong? Thank you
what happened if you power up the relay and enable them?
