3 Door Garage Opener via ESP8266

[nickjmassa]

The hardware setup is a bit janky, but works great. I eventually plan to 3d print a bracket in the box for the relays and ESP8266. Garage doors are triggered by a simple close of the wire loop via relays. Microcontroller is a HiLetGo ESP8266 NodeMCU 12E.

• Black wires go to ground from reed switch or DC- on the relay.
• Red wires go from VIN to DC+ on relays that provides 5v.
• Yellow wires go from GPIO to relays (door trigger).
• Green wires go from GPIO to reed switches that indicate the door is closed.
• Red/Blue wires on the connector side bridge the relay to the door opener circuit

D1 GPIO5 - North Trigger
D5 GPIO14 - North Sensor
D2 GPIO4- Center Trigger
D6 GPIO12 - Center Sensor
D7 GPIO13 - South Trigger
RX GPIO3 - South Sensor
