The switch is actually triggered when the door is closed.
Wemo maker garage door sensor.
If you just want to be able to open or close your garage door then the wemo maker will suffice.
The wemo alerts will appear on the lock screen.
Darlington npn transistor 1 50 or a relay 2 5 i like the darlington as it is cheaper and solid state and easier to wire up but depending on your specific garage door a relay may be a better solution genie garage doors have a lower contact voltage and a darlington can not bring it close enough to ground to.
Arduino uno rev3 board or likely any arduino will do 25.
I ran both the magnetic door sensor wiring added the 22 2 wiring for length as well as a cat5 cable i had connected to the garage door opener ports red white on the garage door to my master closet.
Seeing most garage doors have terminals on them to connect up a push button switch it is pretty easy to connect up a smart device that can trigger the door when we did this the only option in our region was using a wemo maker.
There was already a 120v wall outlet and all the items needed to keep the wemo maker in a climate controlled environment.
The magnetic sensor and speaker wire are optional.
Garage door was closed or something similar how often.
Magnetic sensor 5 90.
I did coonect it to a sensor so it will show that the sensor has been triggered or not in the wemo app.
Speaker wire 21 42.
It works excellent for that and the setup is very straight forward.
Wemo maker sensor triggered notify me.
I used the wemo maker to operate my garage door opener.
Wemo maker 79 99.
A while back a mate asked me to connect his garage door to his phone.
