Hello! That’s my frist “Give to the community”
I have a special situation in my home, and I bet it’s very common, especially in Europe.
My doorbell switch is on a wall in the street, and my Video Doorbell (a Great Reolink Video Doorbell) is about 1,5meters from the closed gate. So, because of the lack of support from reolink, to have an external “call” switch, i had to make my own.
As in the image.
Step 1 - Your warranty is now void!
Step 2 - Wire a line to the switch and use a screw hole as ground.
Note (After a direct connection to the wall switch, the wire was more than 12 meters and sometimes failed to activate)
Step 3 - use a man-in-the-middle
Note. For the WEMOS D1 Mini i had used a code that forces more volt’s from the GPIO that probably some day will kill it, but thats prototyping!
I used the interior pullup resistor.
Step 4 - The code with a safeguard.

And thats my liitle project!
I didnt make any automation on Homeassistant for now.
bye!!
