Use Relay To Control Garage Door

This can work alongside the existing buttons and remotes.

Use relay to control garage door.

Just follow the below simple rule. Output pins are connected to relays. The fibaro relay switch dry contact could be used in parallel with the existing push button contacts as shown in the blow picture. Relay 1 is wired in the standard way and is tied to my visor control.

Two digital pins of arduino are initialized as output to control the garage door and light. The vu offers usb power 5v which is required to power the relay. Relay 2 however is used only for the goodnight scene. Connecting it to vin or 3v will not work.

But i believe there is just one vu pin for the red relay cable on the nodemcu. In this case it will emulate the switch in the wall mounted or portable remote that you currently use to open the garage door. I should note that you should never install the relay board on a garage door which does not have safety features of stopping due to obstructions like vehicles objects or children. The board is all ready to go.

Connections are not difficult. A fibaro relay switch could be used to control the garage doors as described below. Garage shutter door and light are activated by user. If the door is closed the relay is open interrupting the pulse signal getting to the garage motor controller.

At the output of relay you can connect your light and door motor main power line. The input which is used for the garage door push button could also be used by fibaro relay switch to trigger the open close operation. The project also lets users send a command to the door thus enabling you to. If you want to use the same esp and you are just using relays to turn the sprinkler zones on and off you may want to consider instead using the konnected io code installed on the esp8266 to run those relays plus the momentary relay for the garage door.

The only thing left is to wire it to your garage door. Control monitor your garage door with esp8266 openhab a 5v relay the project consists of an esp8266 5v relay power supply resistors and leds. The elk relay wires between the relay 2 output and the garage motor controller. The esp8266 connects to your local wifi and runs a small web server that responds to simple http get post requests that will be sent to it via openhab.

Many garage doors have a beam that when tripped will stop the door. My garage door opener comes with 4 terminals. The two left most terminals are to control the. You can switch the d1 d2 power and ground pins as you see fit.
