WhatsApp Bridge for Home Assistant

A professional, seamless integration to send WhatsApp messages through the Bahmcloud Bridge. This integration supports multiple profiles, dynamic entity-based selection, and broadcast capabilities with native Home Assistant support.

🚀 Installation

1. Install the Add-on

The Bahmcloud WhatsApp Bridge Add-on must be running for the integration to work:

Navigate to Settings -> Add-ons.
Click Add-on Store -> Three dots (top right) -> Repositories.
Add your Bahmcloud Repository URL.
Search for "WhatsApp Bridge", click Install, and Start.

2. Install the Integration

You can install the integration component via three methods:

HACS (Recommended): Add this repository as a "Custom Repository" in HACS and click Install.
BCS (Bahmcloud Store): Search for "WhatsApp Bridge" in the BCS interface.
Manual: Copy the custom_components/whatsapp_bridge_integration folder into your /config/custom_components/ directory and restart Home Assistant.

👥 Configuration & Profiles

Add your WhatsApp accounts via the Home Assistant UI:

Go to Settings -> Devices & Services.
Click Add Integration and search for WhatsApp Bridge.
Follow the setup to add an Account Name (e.g., "Work") and your Phone Number.
Repeat this process for as many accounts as you need.

Resulting Entities

The integration automatically creates sensors for your UI:

sensor.whatsapp_account_name: An entity for each individual account.
sensor.whatsapp_broadcast_all: A global entity to message all accounts at once.

🛠 Usage

Action: `send_message`

This integration registers a service/action to send messages.

Fields:

Recipient: Select an account from the dropdown, choose the "Broadcast" entity, or manually type a phone number.
Message: The text content you wish to send.

YAML Example:

action: whatsapp_bridge_integration.send_message
data:
  recipient: "sensor.whatsapp_rene"
  message: "The garage door is still open!"

⚠️ Important Notes

Phone Numbers: Always use the international format without + or 00 (e.g., 49... for Germany).

Local Network: The integration communicates locally with the Add-on on port 3000.

🤖 Node-RED Integration

The integration is fully compatible with Node-RED. Since it uses native entities, you can use the standard Action (Call Service) node.

Example: Smart Window Warning

Notify yourself if a window or door has been left open for 15 minutes.

Trigger: Use a State Trigger or Device node.
Logic (Change Node): Use JSONata to create a dynamic message:

Set: msg.payload
Value (JSONata): payload.to_state.attributes.friendly_name & " has been open for 15 minutes!"

WhatsApp Node (Action Node):

Action: whatsapp_bridge_integration.send_message
Data (JSON):

{
   "recipient": "sensor.whatsapp_broadcast_all",
   "message": "{{payload}}"
}

Manual Tool Calling

To send a message to a number not saved as a profile, simply pass the raw phone number to the recipient field in your Node-RED JSON:

{
  "recipient": "491701234567",
  "message": "Direct alert to external number."
}

✨ Features

Dynamic UI: Accounts are automatically added to the recipient dropdown.
One-Click Broadcast: Special entity to reach all configured profiles instantly.
Manual Fallback: Clean UI remains flexible; type any number to bypass profiles.
Developer Friendly: Designed for easy integration with Node-RED and HA Automations.
