Future Enhancements

Display & Feedback

  • Show HA entity states on the LCD — door/window sensor names when zones open
  • The second line can show all events in the past minute, like door closed, motion detected, etc..
  • Notification display — push HA notifications (doorbell, washer done) to LCD

Tones & Alerts

  • play single chime (tone 1) on vehicle detected when vehicle detector on
  • play two chime (tone 2) on person detected when person detector on

Presence & Automation

  • Auto-backlight — turn on backlight via motion sensor, off after timeout
  • Presence-based greeting — show personalized message when someone arrives home

Operational

  • Health check endpoint — expose HTTP /health for container monitoring
  • Uptime sensor — publish keypad uptime as an HA sensor
  • Serial reconnect — auto-reconnect if USB serial disconnects and reattaches

HA Automation Prompts

The following items need HA automations. Each section is a self-contained prompt you can give to your HA agent.

1. Door/window sensor names on LCD line 1

Create an automation that shows which doors/windows are currently open on the keypad LCD.

Trigger: Any binary_sensor with device_class "door" or "window" changes state.

Action: Collect all binary_sensors with device_class door/window that are currently "on" (open). Join their friendly names (truncated to fit) into a string. Publish via MQTT:

  • Topic: homeassistant/6160/message/1/set
  • Payload: the joined string (max 16 chars), or "All Secure" if none are open

Example payloads: "Front Door", "Front Dr,Garage", "All Secure"

2. Events on LCD line 2

Create an automation that shows recent events on the keypad LCD second line.

Trigger: State change on any binary_sensor with device_class "door", "window", "motion", or "occupancy".

Action: Publish the event to MQTT:

  • Topic: homeassistant/6160/message/2/set
  • Payload: friendly_name + " " + new state (e.g. "Front Door Open", "Hall Motion On"), truncated to 16 chars

Note: The keypad service auto-updates line 2 with the clock every minute, so events naturally expire after ~60 seconds.

3. Notification display on LCD line 1

Create an automation that pushes HA notifications to the keypad LCD.

Trigger: Event type mobile_app_notification_action or state change on specific notification entities (doorbell ring, washer/dryer done, etc.).

Action: Publish to MQTT:

  • Topic: homeassistant/6160/message/1/set
  • Payload: short notification text, max 16 chars (e.g. "Doorbell Ring", "Washer Done")

4. Vehicle detected chime (tone 1)

Create an automation that plays a single chime on the keypad when a vehicle is detected.

Trigger: A vehicle detection binary_sensor (e.g. from Frigate or a driveway sensor) turns "on".

Condition: Only trigger when a vehicle detection toggle/input_boolean is enabled (so chimes can be silenced).

Action: Publish to MQTT:

  • Topic: homeassistant/6160/tone/set
  • Payload: 1

5. Person detected chime (tone 2)

Create an automation that plays a double chime on the keypad when a person is detected.

Trigger: A person detection binary_sensor (e.g. from Frigate) turns "on".

Condition: Only trigger when a person detection toggle/input_boolean is enabled.

Action: Publish to MQTT:

  • Topic: homeassistant/6160/tone/set
  • Payload: 2

6. Auto-backlight via motion sensor

Create an automation that turns on the keypad backlight when motion is detected nearby, and turns it off after a timeout.

Trigger: A motion sensor near the keypad (e.g. hallway motion) turns "on".

Action: Publish to MQTT:

  • Topic: homeassistant/6160/backlight/set
  • Payload: ON

Second automation (off after timeout): Trigger: The same motion sensor turns "off". Delay: Wait 2 minutes (configurable). Action: Publish to MQTT:

  • Topic: homeassistant/6160/backlight/set
  • Payload: OFF

7. Presence-based greeting

Create an automation that shows a personalized greeting when someone arrives home.

Trigger: A person entity (e.g. person.brian) changes to "home".

Action: Publish to MQTT:

  • Topic: homeassistant/6160/message/1/set
  • Payload: "Welcome Brian" (use the person's name, max 16 chars)

Follow-up (clear after 30s): Delay: 30 seconds. Action: Publish to MQTT:

  • Topic: homeassistant/6160/message/1/set
  • Payload: "" (empty to clear)
