My Grove Smart Plant Care Kit had a problem with one of the wires coming loose from the water pump. I soldered the wire connection back to the pump, but it is not reacting when trying to water. The relay is clicking, the OLED screen is indicating that it is trying to water, but the pump is silent. Is there a way to determine if power is reaching the water pump?
Please connect the red/black wire from pump directly to 12v power supply/gnd and bypass the replay. if the pump does not work, the pump is dead. thanks.
