I have a detached garage and needed a way to tell if the garage overhead door was open or not without leaving the house.
There is a small issue with the code that I am unable to fix. When the door is open, there is a way for me to disable open door notification. when the door is closed, the open door notification reset. However after the garage door is closed, I m still able to toggle the disabled notification in the blynk app, which basically doesnt do anything however lets stay I forgot about it and somone else in the family used the garage door, i would keep getting door open notification with the disable option highlighted in blynk.
- hardware includes
wemos d1 mini micro controller
PC817 octo isolator for the relays
reed switch for door open or close feedback
Samsung S8 android blynk app
