ESPHome Wiegand Reader for Garage Keypad 🔑

Let’s automate your garage! 🚗

Tired of fumbling for keys or remote controls? It’s time to upgrade your garage with a smart keypad! In this guide, we’ll show you how to build a custom solution using an ESP8266 D1 Mini, a Wiegand keypad, and the powerful ESPHome framework. 🛠️

Understanding the Code 💻

Before we dive into the hardware, let’s break down the ESPHome code:

YAML

esphome:
  name: garage-keypad

esp8266:
  board: d1_mini

# Enable logging
logger:

# Enable Home Assistant API
api:

ota:
  platform: esphome
  password: 

wifi:
  ssid: "YOUR_SSID"
  password: "YOUR_PASSWORD"

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid:   1. www.makeriot2020.com www.makeriot2020.com "Garage-Keypad Fallback Hotspot"
    password: "FALLBACK_PASSWORD"

captive_portal:


wiegand:
  - id: mykeypad
    d0: D1
    d1: D2
    on_tag:
      then:
        - homeassistant.tag_scanned: !lambda 'return x;'

This code sets up a basic ESPHome configuration for a D1 Mini, enabling WiFi connectivity, logging, and communication with Home Assistant. The magic happens with the wiegand component, which reads data from the keypad and sends it to Home Assistant. 🪄 Additional information can be found on https://esphome.io/components/wiegand.html
