Garage door control

Assuming you have a regular garage door opener and want to upgrade it with smart capabilities. For example to open and close the garage door from your smart phone, check the state if it is open or closed, and get a notification when it opens when you are away. Just add an ESP node with a relay and some magnet sensors and program it to do that.

Work in progress below.

Hardware

This project is based on the following components:

  • Lolin D1 mini
  • USB charger and cable
  • Relay module 5 V (link External link)
  • Magnet sensor, 2 sets (link External link)
  • Resistor 100 ohm, 2 pieces
  • Resistor 10k ohm, 2 pieces
  • Signal cable with 4 leads (link External link)

Programming of the ESP node is done with ESPHome.

Wiring

The components are connected to the ESP node according to the following wiring diagram.

ESP-node wired as garage door control with end stop sensors.

Programming

Adapt the following program to suit your installation and upload to the ESP node. Replace the listed strings in the code to suit your specific setup:

  • NODE_NAME
  • NODE_NAME_API_KEY
  • NODE_NAME_OTA_PASSWORD
  • WIFI_NAME
  • WIFI_PASSWORD
  • NODE_NAME_FALLBACK_WIFI
  • NODE_NAME_FALLBACK_PASSWORD
