Sonoff switch garage door.
No idea how to retrofit.
Powerretain 1 makes the state of the door being open or closed be retained during a home assistant reboot.
This rule watches the tuyamcu packets for the garage door state open or closed via the magnetic reed switch attached to the door.
Remote control automate monitor home devices like lights temperature and more.
The door sensor reed switch is now power2.
Solder 2 lengths of small wire one on the input and one on the output these wires will connect to the switch contacts on your garage door motor.
It is an absolutely affordable wifi garage door opener that can be triggered to open or close the garage door through your smartphone instead of leaving your car.
Connect female end of jumper wires to gpio 14 and ground.
This rule toggles the fake relay on the tasmota gui and can be monitored via the power1 mqtt topic.
Use a usb cable for power.
Now here is the garage door binary sensor for the reed switch.
After setting up the wifi data the device will restart.
The rest is the save as when flashing sonoff.
Plug the microusb cable to the nodemcu and while pressing the flash button plug in the usb into your computer.
Also note that again yours could be named sonoff and mine is named sonoffgarage.
These are going to the reed switch and will tell you if the garage is open or closed.
Here sonoff 4chpror2 wifi smart switch is a worthy investment.
