Esp easy relay garage door.
1 make a circuit divider with 2 resistors.
If this one is too higher than 5v you will have 2 choices.
That s all a garage door opener does the wired button you likely have next to the door is a simple momentary switch.
Controlling your garage doors with an esp32 part 1.
The garage opener i bought is called boxer 3000 and it seems similar to almost all other openers on the market.
With the addition of a magnetic door sensor we get the added benefit of knowing whether the door is open or closed.
One for opening and another one for closing the garage door.
Always put the esp8266 gnd to the garage motor operner.
I added a pull down resistor 10kohm to ensure the pin is low when the board is powered up and the garage door not accidentally opened.
Setting up a garage door opener i recently installed an automatic door opener in my garage and of course i wanted to hook it up to my openhab system.
Smartthings triggers the relay which completes the circuit pushing the garage door opener button.

This is what i did.
Relays are simple electronics components that allow you to switch a high load using only a single pin on your board.
Garage door control.
Did you forget to close the garage.
When either one of them is turned on for a short period of time the close open action begins.
Learning programming made easy.
Four years ago i got to wire up a raspberry pi to a 2 channel relay and a couple of sensors and hook it up to my garage door openers.
One press starts or stops the.
I used an esp8266 nodemcu with a 5v relay connected normally open directly to the terminals on the back of the garage door opener unit.
2 install a separate magnet switch also attention to the polarity when connecting the relay board to the garage opener.
In this instructable we re going to recreate that momentary switch and with esp module make it web enabled.
The reason i wanted this was to be able to close my garage door remotely in case i left it open accidentally.

With shelly 1 when leaving home you can easily open and close your garage door without worrying that you may have left it open.
Since the relay i had available contained a 5v coil and the wemos board can only output 3 3v on a digital pin i used a transistor to switch the coil on the relay.
Every time the input signal switches on the current flowing through the coil induces a magnetic field that closes a contact.
Simple garage door the following is a possible configuration file for garage doors that are controlled by two relays.
