Home Assistant Garage Door Keypad

This project allows Home Assistant to host a publically exposed page allowing someone to enter a sequence of digits like those old RF garage door keypads.

Setup

1. Copy/merge the contents of the /config folder into your own. Additionally:

   • This project requires Home Assistant Packages turned on in configuration.yaml
   • Update your secrets.yaml file to include an garage_door_code_webhook_id entry

2. Update the automation in /config/packages/garage_door_keypad.yaml:

   • Update the notify.notify service calls (or remove them if you don't want notifications)
   • Update the garage-open service (do a Ctrl+F for "WEBHOOK_ACTION")

3. Set the value of the input_text.garage_door_code entity in Home Assistant

4. Create an NFC tag with a URL that points to:

   https://YOUR_HA_INSTANCE:PORT/local/garage_door_code/index.html?webhook_id=YOUR_GARAGE_DOOR_CODE_WEBHOOK_ID
   

5. And you're done! ✅

Notes/Use

• The interface is mobile-specific — it's tested on Chrome/Android10, and Safari/iOS14
• The interface features dark/light mode
• In your Home Assistant instance, you can modify the keypad code via input_text.garage_door_code. If you set it to a blank value (empty string), the system will be "disabled" and no codes will work.
• The timer.until_garage_door_code_can_be_used controls a server-side cooldown (so that nobody can rapidly brute-force the codes) — if you change its duration, make sure to change the COOLDOWN constant in script.js
• Because the webhook ID is placed in the URL, it is PUBLICALLY EXPOSED TO ANYONE THAT HAS ACCESS TO THE NFC TAG! The automation doesn't allow you to perform any other actions with the webhook ID, as long as you make sure you don't use it in place of other webhooks that expose other services.
