Here is a prototype of my new project. This is a WiFi garage door opener made using the wemos D1 mini module, a relay and the blynk.io platform, working great so far! The only concern I have is if the power goes out it might switch the relay by itself and open the garage door when I am not home. 8

The code for this project is really simple but if someone wants me to share it just please leave a comment. It also includes a function for a reed switch so that you can see if the garage door is closed in the dashboard, I am planning on adding a reed switch to my project soon as well.
Is it not possible to reverse the wiring of the relay so it is normally closed instead of normally open? Wire it so that whatever the default function without power keeps the door closed
How will the garage door open if the power goes out you dummy
I thought about making a more refined version of this project with some less problematic coding and a 3d prinder enclosure and selling it online, do you guys think it’s a good idea?
So test that
Connect the WeMos to the same ups the garage door is connected to
so, don’t install it!!!
What is the point in ability to open garage door in London while driving by the sea in Malibu???
O.K. we know it is possible, but why would we want it??
I assume you mean the relay gets activated when the Wemos module boots up? The solution is to use a pull down resistor go Ground (or pull up, depending on what you want the default behavior to be) so that the pin that controls the relay doesn’t “float around” while booting.
