The garage door remote usually operates with 12v but gets the job done with 5v as well.
Esp8266 12e relay garage door opener.

Putting the lid back on and everything is hidden from view.
And it s never been easier for diyers to make their own home automation components.
Always put the esp8266 gnd to the garage motor operner.
I also use openhab home automation and included mqtt to be useful with that.
Smartthings triggers the relay which completes the circuit pushing the garage door opener button.
Nodemcu is powered by a microusb 5v and steps it down to 3 3v for the esp8266.
Not long ago you had to shop online for smart home gizmos but now even the home improvement stores have a pret.
Connections for the circuit are given.

L298d motor driver module has an inbuilt 5v supply but if you are using l293d ic then you have to make a 5v power supply circuit using 7805 ic.
Esp8266 wifi garage door remote.
Dht22 am2303 temperature humidity sensor.
By accessing pin vin we can still get 5v out to supply power to the 5v relay and the garage door remote.
If this one is too higher than 5v you will have 2 choices.
Connecting it to vin or 3v will not work.
You can switch the d1 d2 power and ground pins as you see fit.
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.
You can control anything with your phone nowadays.
My garage door opener comes with 4 terminals.
The vu offers usb power 5v which is required to power the relay.
The reason i wanted this was to be able to close my garage door remotely in case i left it open accidentally.
The two left most terminals are to control the.
But i believe there is just one vu pin for the red relay cable on the nodemcu.
Complete circuit diagram for smart garage door opener is given below.
Use your multi meter to check the input of your garage door.
1 make a circuit divider with 2 resistors.
2 install a separate magnet switch also attention to the polarity when connecting the relay board to the garage opener.
I haven t been able to get the fake light to indicate if the garage door is open just yet.
The shelly is connected to the garage door opener s logic board to toggle the state and also received 24v of power from it.
We use our garage more like a main entrance to the house because using the actual front entrance tracks a lot of dirt into the house due to the poor layout.
Warning it will oscillate if you fallow the other tutorials i tried the transistor and also using the opto isolator connected to ground but both pull the esp too close to ground it shorts out and will keep resetting itself.
In this project we will use an esp8266 with cayenne to control a garage door opener.
During the rainy season here on the west coast of canada it s even worse.
