The magnetic sensor and speaker wire are optional.
Wemo maker garage door sensor.
Wemo maker 79 99.
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.
Magnetic sensor 5 90.
There was already a 120v wall outlet and all the items needed to keep the wemo maker in a climate controlled environment.
I use ifff to pair the maker with my wemo light switch so i can use a long press on the switch to open my garage door.
It works excellent for that and the setup is very straight forward.
A while back a mate asked me to connect his garage door to his phone.
Garage door was closed or something similar how often.
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.
Wemo maker sensor triggered notify me.
I did coonect it to a sensor so it will show that the sensor has been triggered or not in the wemo app.
If you want to know when the garage door is open or closed then you will need them.
The switch is actually triggered when the door is closed.
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.
I used the wemo maker to operate my garage door opener.
If you just want to be able to open or close your garage door then the wemo maker will suffice.
Arduino uno rev3 board or likely any arduino will do 25.
