The green screw terminal comes firmly inserted into the relay. With your hands or a spudger, pull the screw terminal out of the relay's case. This part may require some extra force to pull it out. |

Using a flathead screwdriver, unscrew each of the screw terminals. |

With the STEMMA male header cable, push the white cable into the left screw terminal. Screw the terminal screw clock-wise to fasten the cable. Make sure to give it it a very gentle tug to make sure it's securely attached! Repeat the above steps for the black header cable and the right screw terminal. Ignore the red (power) header cable. |
Push the screw terminal back into the relay.
Plug the JST PH 3-pin header into the PyPortal's D3 port. |
The PyPortal needs constant power to receive commands from Adafruit IO. The relay has an always ON port which does not get toggled by the PyPortal.
Plug a power adapter (at least 5V 2A) into the relay's always ON port.
Connect the PyPortal to the power adapter's MicroUSB cable. |
Connect the power adapter of the appliance to one of the two normally OFF ports on the relay.
